1
00:00:00.040 --> 00:00:02.480
<v Speaker 1>Hey everyone, and welcome back for another deep dive.

2
00:00:02.879 --> 00:00:04.400
<v Speaker 2>Yes, welcome back.

3
00:00:04.559 --> 00:00:05.960
<v Speaker 1>Today we're picking some locks.

4
00:00:06.280 --> 00:00:08.320
<v Speaker 2>Ooh that sounds fun.

5
00:00:08.439 --> 00:00:11.119
<v Speaker 1>It is fun. It's actually a really fascinating topic. I mean,

6
00:00:11.160 --> 00:00:14.560
<v Speaker 1>who doesn't love a good lock exactly? So we're talking

7
00:00:14.640 --> 00:00:17.839
<v Speaker 1>all about locks and locksmithing. And we've got a great

8
00:00:17.879 --> 00:00:20.600
<v Speaker 1>source for this one, Yes we do. It's the Complete

9
00:00:20.679 --> 00:00:23.559
<v Speaker 1>Book of Locks and Locksmithing by Bill Phillips.

10
00:00:23.760 --> 00:00:25.160
<v Speaker 2>This book is awesome.

11
00:00:25.359 --> 00:00:28.199
<v Speaker 1>Yeah, and even in the forward, Greg Mango, who's a

12
00:00:28.280 --> 00:00:31.960
<v Speaker 1>veteran locksmith, calls it a treasure trove of information, so

13
00:00:32.640 --> 00:00:35.159
<v Speaker 1>he's not a line. We're in good hands with this one. Yeah.

14
00:00:35.159 --> 00:00:37.479
<v Speaker 1>So where do we even begin with locks? I mean

15
00:00:37.520 --> 00:00:38.920
<v Speaker 1>we're everywhere.

16
00:00:38.520 --> 00:00:41.520
<v Speaker 2>Right, everywhere, you know, and we just take them for granted,

17
00:00:41.719 --> 00:00:44.079
<v Speaker 2>we do. But the history is fascinating.

18
00:00:44.280 --> 00:00:46.719
<v Speaker 1>Yeah, and I was surprised to learn that locks have

19
00:00:46.799 --> 00:00:48.439
<v Speaker 1>been around for centuries.

20
00:00:48.520 --> 00:00:53.159
<v Speaker 2>Oh yeah, like way back, like ancient times, ancient civilizations. Yeah,

21
00:00:53.159 --> 00:00:56.359
<v Speaker 2>the Egyptians four thousand years ago, they had locks that

22
00:00:56.399 --> 00:00:58.479
<v Speaker 2>are similar to what we use today.

23
00:00:58.640 --> 00:01:00.719
<v Speaker 1>Really, I would have thought pinned tumbler locks were a

24
00:01:00.799 --> 00:01:02.240
<v Speaker 1>much more recent invention.

25
00:01:02.240 --> 00:01:06.159
<v Speaker 2>Right, but no, the Egyptians were using wood to create

26
00:01:06.200 --> 00:01:10.000
<v Speaker 2>these locking mechanisms wood like a wooden bolt with wooden

27
00:01:10.040 --> 00:01:11.400
<v Speaker 2>pins and a wooden key.

28
00:01:12.000 --> 00:01:14.719
<v Speaker 1>It's amazing, that's incredible. So it's like a really early

29
00:01:14.840 --> 00:01:16.799
<v Speaker 1>version of a pin tumbler lock exactly.

30
00:01:16.840 --> 00:01:18.159
<v Speaker 2>The basic principle is the same.

31
00:01:18.239 --> 00:01:20.640
<v Speaker 1>Wow. So I guess the need for security has been

32
00:01:20.680 --> 00:01:21.599
<v Speaker 1>around forever.

33
00:01:21.840 --> 00:01:22.480
<v Speaker 2>Absolutely.

34
00:01:22.680 --> 00:01:25.480
<v Speaker 1>What about other ancient cultures do they have similar locks?

35
00:01:25.959 --> 00:01:29.280
<v Speaker 2>It's interesting because you see variations. So like ancient Greece

36
00:01:29.719 --> 00:01:33.280
<v Speaker 2>they relied a lot on rope knots and warded locks.

37
00:01:33.359 --> 00:01:36.439
<v Speaker 1>Rope knots really yeah, pretty clever.

38
00:01:36.519 --> 00:01:38.400
<v Speaker 2>Actually, I guess back then it was more about the

39
00:01:38.400 --> 00:01:42.319
<v Speaker 2>fear of tampering with the knot than any complex mechanism.

40
00:01:42.000 --> 00:01:43.959
<v Speaker 1>Right, it was a different mindset about security.

41
00:01:44.560 --> 00:01:48.079
<v Speaker 2>So when do we start seeing those more complex locks.

42
00:01:48.599 --> 00:01:50.480
<v Speaker 1>Well, things really start to pick up in the eighteenth

43
00:01:50.560 --> 00:01:52.560
<v Speaker 1>century in England, especially in England.

44
00:01:52.599 --> 00:01:54.920
<v Speaker 2>Yeah, that's when lever tumbler locks come into the picture,

45
00:01:55.000 --> 00:01:55.879
<v Speaker 2>right exactly.

46
00:01:56.040 --> 00:01:59.159
<v Speaker 1>Robert Barn's invention was a game changer. It made picking

47
00:01:59.200 --> 00:02:00.439
<v Speaker 1>locks much harder.

48
00:02:00.640 --> 00:02:03.560
<v Speaker 2>So how did those lever tumbler locks work? Think of

49
00:02:03.680 --> 00:02:06.840
<v Speaker 2>levels that need to be lifted to specific heights for the.

50
00:02:06.760 --> 00:02:09.199
<v Speaker 1>Lock to open, like a multi layered puzzle.

51
00:02:09.039 --> 00:02:12.840
<v Speaker 2>Exactly, and the key has this unique bidding that lifts

52
00:02:12.879 --> 00:02:14.439
<v Speaker 2>the levers just right.

53
00:02:14.680 --> 00:02:17.719
<v Speaker 1>So that's why they were considered more secure than warded locks.

54
00:02:17.599 --> 00:02:20.680
<v Speaker 2>Much more secure, and this innovation really sparked a wave

55
00:02:20.719 --> 00:02:22.560
<v Speaker 2>of creativity among the locksmith's.

56
00:02:22.680 --> 00:02:26.520
<v Speaker 1>Yeah, you had all those famous names like Joseph Brahma

57
00:02:26.639 --> 00:02:27.680
<v Speaker 1>and Jeremiah Chubb.

58
00:02:27.800 --> 00:02:30.360
<v Speaker 2>Oh yeah, they were like the rock stars of locksmith thing.

59
00:02:30.520 --> 00:02:32.800
<v Speaker 1>It was like an arms race to create the most

60
00:02:32.879 --> 00:02:33.680
<v Speaker 1>secure lock.

61
00:02:33.840 --> 00:02:37.439
<v Speaker 2>It was until this American locksmith, Ac Hobbs came along.

62
00:02:37.599 --> 00:02:41.599
<v Speaker 1>He's the one who picked Brahma's supposedly unpickable lock, right.

63
00:02:41.560 --> 00:02:43.360
<v Speaker 2>Yeah, at the Great Exhibition in London.

64
00:02:43.479 --> 00:02:44.479
<v Speaker 1>Al must have been quite a shock.

65
00:02:44.599 --> 00:02:47.960
<v Speaker 2>Oh, it was huge. It really showed that no lock

66
00:02:48.080 --> 00:02:49.919
<v Speaker 2>is truly unpickable.

67
00:02:49.520 --> 00:02:51.400
<v Speaker 1>So it pushed everyone to keep innovating.

68
00:02:51.520 --> 00:02:52.120
<v Speaker 2>Absolutely.

69
00:02:52.240 --> 00:02:55.439
<v Speaker 1>Okay, so we've got warded locks and lever tumbler locks,

70
00:02:55.479 --> 00:02:58.159
<v Speaker 1>all right, but let's talk about the most basic type

71
00:02:58.159 --> 00:03:00.560
<v Speaker 1>of the warded lock. Okay, what made them so easy

72
00:03:00.560 --> 00:03:01.159
<v Speaker 1>to bypass?

73
00:03:01.479 --> 00:03:04.919
<v Speaker 2>So imagine a warded lock like a maze. The key

74
00:03:05.000 --> 00:03:08.719
<v Speaker 2>has to navigate these fixed obstacles called wards. But the

75
00:03:08.759 --> 00:03:11.759
<v Speaker 2>problem is those wards are fixed, so with the right tools,

76
00:03:11.759 --> 00:03:14.599
<v Speaker 2>you can manipulate them and open the lock without the key.

77
00:03:14.800 --> 00:03:17.599
<v Speaker 1>So it's more about getting past the obstacles than matching

78
00:03:17.599 --> 00:03:18.800
<v Speaker 1>a specific key.

79
00:03:18.759 --> 00:03:22.400
<v Speaker 2>Exactly, and that's why warded locks eventually gave way to

80
00:03:22.599 --> 00:03:24.919
<v Speaker 2>more secure designs like lever tumbler locks.

81
00:03:25.360 --> 00:03:28.199
<v Speaker 1>And from there we get to the pin tumbler lock

82
00:03:28.479 --> 00:03:30.159
<v Speaker 1>the start of the show, the one we see on

83
00:03:30.240 --> 00:03:31.120
<v Speaker 1>most doors today.

84
00:03:31.240 --> 00:03:35.159
<v Speaker 2>Yep, they're reliable, affordable, and pretty darn secure.

85
00:03:35.680 --> 00:03:38.159
<v Speaker 1>So remind me again how those pin tumbler locks work.

86
00:03:38.520 --> 00:03:42.599
<v Speaker 2>So picture a cylinder with spring loaded pins of different lengths. Okay,

87
00:03:42.840 --> 00:03:46.439
<v Speaker 2>these pins block the cylinder from turning. The key is

88
00:03:46.479 --> 00:03:48.919
<v Speaker 2>what aligns those pins to a specific height.

89
00:03:49.240 --> 00:03:51.360
<v Speaker 1>So each key has a unique arrangement of.

90
00:03:51.360 --> 00:03:54.919
<v Speaker 2>Pins exactly, And when you insert the correct key, it

91
00:03:55.000 --> 00:03:57.240
<v Speaker 2>pushes the pins up and they align with this thing

92
00:03:57.280 --> 00:03:58.159
<v Speaker 2>called the sheer line.

93
00:03:58.240 --> 00:03:58.800
<v Speaker 1>The sheer lin.

94
00:03:58.919 --> 00:04:00.960
<v Speaker 2>Yeah, it's like the sweet spot where the cylinder can

95
00:04:01.080 --> 00:04:01.840
<v Speaker 2>rotate freely.

96
00:04:01.960 --> 00:04:03.599
<v Speaker 1>All I see. So if the pins aren't aligned at

97
00:04:03.599 --> 00:04:05.719
<v Speaker 1>the sheer line, the lock stays shut exactly.

98
00:04:05.719 --> 00:04:06.680
<v Speaker 2>It's all about precision.

99
00:04:06.840 --> 00:04:08.919
<v Speaker 1>And what about the different parts of the lock itself.

100
00:04:09.159 --> 00:04:11.759
<v Speaker 2>Okay, so you've got the shell, which is the outer casing.

101
00:04:12.479 --> 00:04:15.400
<v Speaker 2>Then you've got the plug, which is the part that rotates, and.

102
00:04:15.360 --> 00:04:16.720
<v Speaker 1>The pins are inside the plug.

103
00:04:16.959 --> 00:04:20.279
<v Speaker 2>Right, You've got bottom pins and top pins, and they're

104
00:04:20.360 --> 00:04:23.720
<v Speaker 2>spring loaded, so they're always pushing down to keep the

105
00:04:23.759 --> 00:04:24.920
<v Speaker 2>lock secure.

106
00:04:24.720 --> 00:04:27.279
<v Speaker 1>Unless the right key comes along and lists them up exactly.

107
00:04:27.720 --> 00:04:30.079
<v Speaker 2>And then there's the keyway, which is the slot where

108
00:04:30.079 --> 00:04:31.000
<v Speaker 2>you insert the key.

109
00:04:31.120 --> 00:04:33.600
<v Speaker 1>Okay, So the key lifts the pins, they align at

110
00:04:33.639 --> 00:04:35.480
<v Speaker 1>the sheer line, and the lock opens.

111
00:04:35.600 --> 00:04:36.120
<v Speaker 2>Boom.

112
00:04:36.199 --> 00:04:38.240
<v Speaker 1>It's amazing how all those little parts work together.

113
00:04:38.319 --> 00:04:39.199
<v Speaker 2>It's a beautiful thing.

114
00:04:39.399 --> 00:04:42.120
<v Speaker 1>What about master key systems those always seem kind of

115
00:04:42.120 --> 00:04:42.720
<v Speaker 1>magical to me.

116
00:04:42.920 --> 00:04:43.920
<v Speaker 2>They are pretty cool.

117
00:04:44.079 --> 00:04:48.000
<v Speaker 1>How can one key open multiple locks with different pin arrangements?

118
00:04:48.439 --> 00:04:53.240
<v Speaker 2>So master key systems use these extra pins called master pins, okay,

119
00:04:53.519 --> 00:04:58.360
<v Speaker 2>and these master pins create multiple sheer lines within the lock, so.

120
00:04:58.279 --> 00:05:01.600
<v Speaker 1>Instead of just one unlocked position, there multiple positions precisely.

121
00:05:01.680 --> 00:05:04.120
<v Speaker 2>So a change key will align one set of pins,

122
00:05:04.560 --> 00:05:07.600
<v Speaker 2>and a master key will align a different set, including

123
00:05:07.600 --> 00:05:08.639
<v Speaker 2>those master pins.

124
00:05:08.759 --> 00:05:12.040
<v Speaker 1>That's so clever. It's like having multiple secret handshakes within.

125
00:05:11.879 --> 00:05:16.120
<v Speaker 2>The lock exactly. But designing these systems is complex. You

126
00:05:16.199 --> 00:05:18.959
<v Speaker 2>have to make sure each key only grants access to

127
00:05:19.000 --> 00:05:19.959
<v Speaker 2>the intended locks.

128
00:05:20.040 --> 00:05:23.920
<v Speaker 1>Yeah. Security is key. Literally, it's mind blowing how much

129
00:05:23.959 --> 00:05:26.360
<v Speaker 1>goes into something as seemingly simple as a lock.

130
00:05:26.560 --> 00:05:29.680
<v Speaker 2>And we're just getting started. There's so much more to explore.

131
00:05:29.879 --> 00:05:33.360
<v Speaker 1>I can't wait me neither, buckle up, Let's do it.

132
00:05:33.480 --> 00:05:36.639
<v Speaker 2>We're diving deeper into the world of locks and locksmithing.

133
00:05:37.000 --> 00:05:38.360
<v Speaker 1>Awesome, let's go.

134
00:05:39.160 --> 00:05:41.759
<v Speaker 2>You know, it's amazing when you really start looking into it.

135
00:05:42.079 --> 00:05:44.279
<v Speaker 2>There are so many kinds of locks out there.

136
00:05:44.360 --> 00:05:46.959
<v Speaker 1>Oh yeah, we've been talking about door locks, but I

137
00:05:46.959 --> 00:05:50.680
<v Speaker 1>mean think about it. It's endless padlocks, bike locks, even

138
00:05:50.680 --> 00:05:53.120
<v Speaker 1>those little TSA locks on luggage.

139
00:05:52.680 --> 00:05:56.680
<v Speaker 2>Exactly, and each type has its own little world of details.

140
00:05:56.959 --> 00:05:59.079
<v Speaker 1>So like with padlocks, is there more to it that

141
00:05:59.160 --> 00:06:00.120
<v Speaker 1>meets the eye? Oh?

142
00:06:00.160 --> 00:06:03.160
<v Speaker 2>Absolutely. You can't just grab any padlock. There are different

143
00:06:03.240 --> 00:06:05.600
<v Speaker 2>levels of security, just like with door locks, right.

144
00:06:05.480 --> 00:06:08.240
<v Speaker 1>Because a bikelock needs to be way tougher than something

145
00:06:08.279 --> 00:06:10.040
<v Speaker 1>just securing a little box exactly.

146
00:06:10.079 --> 00:06:12.759
<v Speaker 2>You have to consider the environment, what someone might try

147
00:06:12.759 --> 00:06:14.160
<v Speaker 2>to break it with makes sense.

148
00:06:14.439 --> 00:06:16.160
<v Speaker 1>So there's no one size fits all padlock.

149
00:06:16.399 --> 00:06:20.199
<v Speaker 2>Nope. And even within say pin tumbler padlocks, there are

150
00:06:20.279 --> 00:06:23.240
<v Speaker 2>so many variations. The way they're built, materials, all that

151
00:06:23.279 --> 00:06:24.720
<v Speaker 2>affects how strong they are.

152
00:06:24.800 --> 00:06:27.480
<v Speaker 1>So you really have to think about what you're protecting

153
00:06:27.959 --> 00:06:31.120
<v Speaker 1>and what kind of security you need exactly. Okay, let's

154
00:06:31.120 --> 00:06:32.519
<v Speaker 1>talk about the heavy hitters safes.

155
00:06:32.959 --> 00:06:35.000
<v Speaker 2>Now we're talking serious security.

156
00:06:35.120 --> 00:06:38.639
<v Speaker 1>When you need to protect something super valuable, a safe

157
00:06:39.120 --> 00:06:40.360
<v Speaker 1>seems like the ultimate solution.

158
00:06:40.720 --> 00:06:43.720
<v Speaker 2>They're built to withstand a lot more than just picking

159
00:06:43.759 --> 00:06:48.360
<v Speaker 2>heavy duty steel, intricate locking mechanism like a bank vault. Yeah,

160
00:06:48.399 --> 00:06:51.439
<v Speaker 2>pretty much. And there are so many types home safes,

161
00:06:51.560 --> 00:06:54.560
<v Speaker 2>gun safes, all the way up to those massive bank vaults.

162
00:06:54.800 --> 00:06:58.160
<v Speaker 1>I guess the main thing is fire resistance and burglary protection.

163
00:06:58.360 --> 00:07:01.399
<v Speaker 2>Right, because a fire safe might not stop someone from

164
00:07:01.399 --> 00:07:02.480
<v Speaker 2>breaking in, So.

165
00:07:02.399 --> 00:07:04.000
<v Speaker 1>You really have to think about what you need the

166
00:07:04.040 --> 00:07:05.040
<v Speaker 1>safe to protect.

167
00:07:04.720 --> 00:07:08.600
<v Speaker 2>Against absolutely and look for safes that meet industry standards

168
00:07:08.759 --> 00:07:09.879
<v Speaker 2>like UL ratings.

169
00:07:09.920 --> 00:07:12.079
<v Speaker 1>So those ratings tell you how well a safe will

170
00:07:12.120 --> 00:07:14.519
<v Speaker 1>hold up against fire or a break in exactly.

171
00:07:14.759 --> 00:07:17.199
<v Speaker 2>That way, you can compare and choose the right level of.

172
00:07:17.120 --> 00:07:19.319
<v Speaker 1>Protection, and the locks on safe for a whole other

173
00:07:19.399 --> 00:07:19.800
<v Speaker 1>level too.

174
00:07:19.959 --> 00:07:25.040
<v Speaker 2>Right. Oh yeah, we're talking complex combination locks, multiple dials,

175
00:07:25.160 --> 00:07:28.560
<v Speaker 2>internal mechanisms designed to be super resistant to tampering.

176
00:07:28.800 --> 00:07:30.680
<v Speaker 1>So not your average combination lock.

177
00:07:30.839 --> 00:07:34.920
<v Speaker 2>Nope, These are serious business. Cracking one of those would

178
00:07:34.920 --> 00:07:37.199
<v Speaker 2>take a lot of skill, time and the right tools.

179
00:07:37.319 --> 00:07:39.759
<v Speaker 1>They're like the fort Knox of locks pretty much.

180
00:07:40.040 --> 00:07:43.279
<v Speaker 2>Plus they often have these relocking devices that trigger if

181
00:07:43.279 --> 00:07:44.600
<v Speaker 2>someone tries to mess with the lock.

182
00:07:44.920 --> 00:07:47.800
<v Speaker 1>Wow. So it's layers upon layers of security exactly.

183
00:07:48.120 --> 00:07:51.439
<v Speaker 2>Choosing a safe is all about understanding your needs, researching

184
00:07:51.480 --> 00:07:54.600
<v Speaker 2>different models, and finding the one that provides the right

185
00:07:54.680 --> 00:07:55.480
<v Speaker 2>level of protection.

186
00:07:56.000 --> 00:07:57.279
<v Speaker 1>It's not something to take lightly.

187
00:07:57.439 --> 00:07:57.839
<v Speaker 2>Nope.

188
00:07:58.000 --> 00:07:59.839
<v Speaker 1>Now let's talk about the people who make all this

189
00:08:00.000 --> 00:08:04.519
<v Speaker 1>security magic happened. Locksmiths, ah, the masters of locks. It

190
00:08:04.519 --> 00:08:06.480
<v Speaker 1>seems like a job that takes a ton of skill

191
00:08:06.519 --> 00:08:07.079
<v Speaker 1>and knowledge.

192
00:08:07.160 --> 00:08:10.199
<v Speaker 2>Oh definitely. Locksmiths are way more than just door openers,

193
00:08:10.240 --> 00:08:13.279
<v Speaker 2>I am having. They're experts in lock mechanics, security systems,

194
00:08:13.360 --> 00:08:14.160
<v Speaker 2>key duplication.

195
00:08:14.639 --> 00:08:17.800
<v Speaker 1>So they're like security consultants for our homes and businesses exactly.

196
00:08:18.240 --> 00:08:22.000
<v Speaker 2>They install in repair locks, rea key systems, create master

197
00:08:22.120 --> 00:08:25.120
<v Speaker 2>key systems, and advise on security upgrades.

198
00:08:25.279 --> 00:08:27.199
<v Speaker 1>It's a lot more than just picking locks.

199
00:08:27.199 --> 00:08:29.879
<v Speaker 2>Right, and with all the new smart locks and electronic

200
00:08:29.920 --> 00:08:32.600
<v Speaker 2>access control systems, their skills are evolving to.

201
00:08:32.919 --> 00:08:36.279
<v Speaker 1>Speaking of which, this book mentions something called lock bumping.

202
00:08:36.600 --> 00:08:37.879
<v Speaker 2>Oh yeah, that's a real thing.

203
00:08:38.480 --> 00:08:40.279
<v Speaker 1>Is it really as easy as it looks in the movies?

204
00:08:40.440 --> 00:08:43.320
<v Speaker 2>Well, it's not quite movie magic. It uses a special

205
00:08:43.399 --> 00:08:46.919
<v Speaker 2>key called a bump key to transfer energy through the

206
00:08:47.000 --> 00:08:48.960
<v Speaker 2>pins and potentially unlock the door.

207
00:08:49.360 --> 00:08:51.279
<v Speaker 1>So you just hit the key and boom, the lock opens.

208
00:08:51.440 --> 00:08:54.200
<v Speaker 2>It's a bit more nuanced than that. The impact has

209
00:08:54.279 --> 00:08:56.559
<v Speaker 2>to be just right, and it can damage the lock

210
00:08:56.600 --> 00:08:59.279
<v Speaker 2>if you don't know what you're doing. Sounds risky, yeah,

211
00:08:59.519 --> 00:09:02.480
<v Speaker 2>definite something to try at home. And it's important to

212
00:09:02.519 --> 00:09:05.639
<v Speaker 2>remember that any technique used to bypass locks should be

213
00:09:05.679 --> 00:09:07.720
<v Speaker 2>done ethically and legally.

214
00:09:07.840 --> 00:09:11.320
<v Speaker 1>So leave it to the professionals. Right now. What about impressioning?

215
00:09:11.360 --> 00:09:13.480
<v Speaker 1>That seems even more specialized than lock picking.

216
00:09:13.759 --> 00:09:18.000
<v Speaker 2>Impressioning is like creating a fingerprint of the lock's internal mechanism.

217
00:09:18.200 --> 00:09:19.320
<v Speaker 1>Okay, how does that work.

218
00:09:19.519 --> 00:09:22.519
<v Speaker 2>You use a blank key and special tools to map

219
00:09:22.559 --> 00:09:25.159
<v Speaker 2>out the lock's pins, filing down the key until it

220
00:09:25.200 --> 00:09:26.120
<v Speaker 2>perfectly matches.

221
00:09:26.440 --> 00:09:29.159
<v Speaker 1>So you're basically making a working key based on the

222
00:09:29.159 --> 00:09:31.480
<v Speaker 1>impressions left by the locks parts exactly.

223
00:09:31.519 --> 00:09:34.320
<v Speaker 2>It's a super precise process, takes a lot of skill

224
00:09:34.399 --> 00:09:35.080
<v Speaker 2>and patience.

225
00:09:35.320 --> 00:09:38.240
<v Speaker 1>I bet so not something just anyone could pick up

226
00:09:38.240 --> 00:09:38.440
<v Speaker 1>and do.

227
00:09:38.639 --> 00:09:41.960
<v Speaker 2>Nope, and as locks get more complex, impressioning gets even.

228
00:09:41.759 --> 00:09:44.159
<v Speaker 1>Harder, which is why manufacturers are always coming up with

229
00:09:44.240 --> 00:09:45.360
<v Speaker 1>new security features.

230
00:09:45.399 --> 00:09:48.320
<v Speaker 2>Absolutely, it's a constant battle between those who want to

231
00:09:48.360 --> 00:09:50.320
<v Speaker 2>create security and those who want to break.

232
00:09:50.080 --> 00:09:52.480
<v Speaker 1>It, a security arms race exactly.

233
00:09:52.720 --> 00:09:56.960
<v Speaker 2>But remember security isn't just about having the strongest locks.

234
00:09:56.840 --> 00:09:59.320
<v Speaker 1>So it's not all about the hardware, right, you have to.

235
00:09:59.240 --> 00:10:01.480
<v Speaker 2>Think about how it's used and implemented, so.

236
00:10:01.519 --> 00:10:04.440
<v Speaker 1>Like making sure doors and windows are properly secured and

237
00:10:04.519 --> 00:10:05.720
<v Speaker 1>not leaving keys lying.

238
00:10:05.519 --> 00:10:09.600
<v Speaker 2>Around, Exactly. It's about taking a holistic approach to security.

239
00:10:09.240 --> 00:10:11.759
<v Speaker 1>Thinking about all the potential weak points.

240
00:10:11.519 --> 00:10:15.000
<v Speaker 2>Right, and that's where locksmiths and security professionals come in.

241
00:10:15.480 --> 00:10:18.679
<v Speaker 2>They can assess your needs and recommend the best combination

242
00:10:18.799 --> 00:10:20.399
<v Speaker 2>of locks, systems and practices.

243
00:10:20.759 --> 00:10:23.720
<v Speaker 1>So it's like having a security expert on your side exactly.

244
00:10:24.320 --> 00:10:26.679
<v Speaker 2>Now, are you ready to step into the future?

245
00:10:27.399 --> 00:10:29.399
<v Speaker 1>Woh? I like where this is going.

246
00:10:29.720 --> 00:10:33.240
<v Speaker 2>Let's talk about electrical access and exit control systems.

247
00:10:33.279 --> 00:10:36.159
<v Speaker 1>Okay, we're moving beyond keys and locks now we are.

248
00:10:36.279 --> 00:10:38.799
<v Speaker 2>This is the next level of security technology.

249
00:10:39.039 --> 00:10:41.879
<v Speaker 1>So are we talking like key card systems or those

250
00:10:41.879 --> 00:10:44.120
<v Speaker 1>biometric scanners you see in spy movies?

251
00:10:44.159 --> 00:10:47.039
<v Speaker 2>You got it? Electrical access control systems can be anything

252
00:10:47.080 --> 00:10:50.480
<v Speaker 2>from simple key card readers to those high tech biometric

253
00:10:50.559 --> 00:10:53.720
<v Speaker 2>scanners that use fingerprints or iris scans, so.

254
00:10:53.639 --> 00:10:56.759
<v Speaker 1>Instead of physical keys, we're using electronic signals to control

255
00:10:56.799 --> 00:10:57.879
<v Speaker 1>access exactly.

256
00:10:58.159 --> 00:11:02.039
<v Speaker 2>And these systems have a ton of advance like what Well,

257
00:11:02.120 --> 00:11:04.960
<v Speaker 2>For one, you can easily grant or revoke access without

258
00:11:04.960 --> 00:11:07.600
<v Speaker 2>having to change any locks. That's super convenient, and you

259
00:11:07.600 --> 00:11:09.720
<v Speaker 2>can track who's coming and going, which is great for

260
00:11:09.799 --> 00:11:11.000
<v Speaker 2>security monitoring, so.

261
00:11:10.960 --> 00:11:14.080
<v Speaker 1>It's like having a digital logbook for your building exactly.

262
00:11:14.279 --> 00:11:17.200
<v Speaker 2>Plus you can integrate these systems with other security measures

263
00:11:17.200 --> 00:11:18.679
<v Speaker 2>like alarms and cameras, so.

264
00:11:18.639 --> 00:11:22.080
<v Speaker 1>It's all connected, creating this web of security exactly.

265
00:11:22.120 --> 00:11:25.519
<v Speaker 2>We're talking about a more holistic and intelligent approach to security.

266
00:11:25.559 --> 00:11:28.080
<v Speaker 1>This is blowing my mind. We've gone from ancient Egyptian

267
00:11:28.120 --> 00:11:31.480
<v Speaker 1>wooden locks to futuristic access control systems.

268
00:11:31.320 --> 00:11:36.159
<v Speaker 2>And it's all driven by that same human desire for security.

269
00:11:36.279 --> 00:11:39.559
<v Speaker 1>It's incredible how much things have evolved, but one.

270
00:11:39.360 --> 00:11:43.639
<v Speaker 2>Thing remains constant, the ingenuity we use to both create

271
00:11:43.679 --> 00:11:47.000
<v Speaker 2>and overcome security measures. It's a never ending game of

272
00:11:47.039 --> 00:11:51.320
<v Speaker 2>cat mouse exactly, and it's what makes this field so fascinating.

273
00:11:51.559 --> 00:11:53.759
<v Speaker 1>It's amazing to think about all the different ways we

274
00:11:53.799 --> 00:11:55.679
<v Speaker 1>try to protect ourselves and our stuff.

275
00:11:55.759 --> 00:11:58.039
<v Speaker 2>It is and it makes you realize that security is

276
00:11:58.039 --> 00:11:59.759
<v Speaker 2>more than just gadgets and gizmos.

277
00:12:00.200 --> 00:12:03.080
<v Speaker 1>It's about understanding the human element too, Exactly.

278
00:12:03.519 --> 00:12:06.559
<v Speaker 2>This book actually delves into some of the legal and

279
00:12:06.679 --> 00:12:08.399
<v Speaker 2>ethical sides of locksmithing.

280
00:12:08.679 --> 00:12:10.600
<v Speaker 1>Yeah, I was surprised by how much of that was

281
00:12:10.639 --> 00:12:10.960
<v Speaker 1>in there.

282
00:12:11.200 --> 00:12:13.759
<v Speaker 2>It's important stuff. I mean, locksmiths have a lot of

283
00:12:13.840 --> 00:12:17.440
<v Speaker 2>knowledge and skill, and it's crucial that they use it responsibly.

284
00:12:17.000 --> 00:12:19.039
<v Speaker 1>Right, because those skills could be used for good or bad.

285
00:12:19.279 --> 00:12:22.039
<v Speaker 2>Exactly. There's a fine line there, and that's why the

286
00:12:22.080 --> 00:12:25.960
<v Speaker 2>locksmithing profession has all sorts of regulations and ethical guidelines.

287
00:12:26.200 --> 00:12:27.919
<v Speaker 1>It's not just about knowing how to pick a lock.

288
00:12:27.960 --> 00:12:30.360
<v Speaker 1>It's about knowing when and why you should right.

289
00:12:30.480 --> 00:12:33.480
<v Speaker 2>It's about building trust and making sure those skills are

290
00:12:33.559 --> 00:12:36.240
<v Speaker 2>used to protect people, not exploit them.

291
00:12:36.720 --> 00:12:38.639
<v Speaker 1>The book even talked about some of the gray areas

292
00:12:38.679 --> 00:12:39.519
<v Speaker 1>locksmith's face.

293
00:12:39.679 --> 00:12:41.559
<v Speaker 2>Oh yeah, like what happens if someone asks you to

294
00:12:41.559 --> 00:12:44.559
<v Speaker 2>copy a key that says do not duplicate, or.

295
00:12:44.559 --> 00:12:46.879
<v Speaker 1>If someone refuses to pay after you've done the work.

296
00:12:46.960 --> 00:12:49.720
<v Speaker 2>Those are tough situations that require a lot of judgment

297
00:12:49.799 --> 00:12:51.200
<v Speaker 2>and understanding of the law.

298
00:12:51.440 --> 00:12:54.200
<v Speaker 1>It really highlights the fact that locksmithing is a profession

299
00:12:54.240 --> 00:12:56.080
<v Speaker 1>built on trust and responsibility.

300
00:12:56.159 --> 00:12:58.639
<v Speaker 2>Absolutely, it's not just about the technical stuff, it's about

301
00:12:58.639 --> 00:12:59.320
<v Speaker 2>the ethics too.

302
00:13:00.120 --> 00:13:03.159
<v Speaker 1>So as we wrap up this deep dive, what are

303
00:13:03.200 --> 00:13:05.159
<v Speaker 1>some key takeaways for our listeners.

304
00:13:05.240 --> 00:13:08.720
<v Speaker 2>Well, I think the biggest thing is awareness. Don't wait

305
00:13:08.799 --> 00:13:12.559
<v Speaker 2>until something bad happens to start thinking about security right,

306
00:13:12.639 --> 00:13:15.960
<v Speaker 2>be proactive exactly. Take some time to think about what

307
00:13:16.000 --> 00:13:18.120
<v Speaker 2>you need to protect and what the potential threats are.
