  • This is the lock picking lawyer, and what I have for you today is one of the most common electronic keypad locks made today.

  • I've seen this used in a variety of different applications, including locking doors, locking heavy machinery and power tools, as well as locking elevators.

  • They're made in China and branded under dozens of company names for demonstration purposes.

  • I've set this up with an electric strike plate.

  • It opens when either the egress button is pressed from the inside of the door, where the correct code is entered from the outside.

  • That code is currently 1234 Now, by passing a lock like this can be very simple.

  • But there are pitfalls for the unwary, the most significant of which is the anti tamper switch on the back.

  • It detects someone removing this plate.

  • Now the overwhelming majority of the time that tamper switch will not be connected to anything.

  • Even so, I'll show you how to bypass the switch using a paper clip, because that's what you'll have to do if you need to look at the wiring.

  • However, if you're familiar with how these air wired and the schematics are readily available, online, you'll realize that disabling the switch isn't necessary.

  • And, frankly, it's often the hard way in the easy way requires nothing but my Swiss Army knife key chain.

  • Let me show you how that's done.

  • The first thing we need to do is loosen these two screws that allows me to look right under the cover plate and find the appropriate contact points.

  • I'm now going to bridge that con contact point to the cover plate, and the lock is open now without going too much into what I just did.

  • I located the contact point for the egress button.

  • I then bridged it to the cover plate, which connects the circuit and fools this lock into thinking someone on the inside of the door pressed the egress button.

  • Now, if this is used in a non typical installation, you'll need to take a closer look at the wiring, and that may require disabling the tamper switch.

  • So let's do that right now.

  • I'm straightening the paperclip with the exception of a small hook, then going to loosen this just a little bit more and find the spring that is attached to the anti tamper switch.

  • Okay, I've hooked that spring.

  • Now I'm going to fold the paper clip over, and that should allow me to remove the screws without any fear of an alarm going off.

  • Okay, now that I flip this over, we can see the anti tamper switch.

  • It's connected to a spring that presses on the back of the electrical box.

  • By pulling that spring to the side, I ensured that anti tamper switch stays depressed and no alarms go off.

  • However, now that I have this out, I see there are no wires going to the anti tamper switch.

  • That means I can let go of this because there's no internal alarm.

  • I can also now see how this is wired.

  • It's in normally open mode.

  • That means I can reached some contacts to open the strike plate.

  • I can also trigger the egress button, and I can also do what you saw me do with the Swiss army knife.

  • And that is touch the egress, Contact Point and Bridget to the cover plate.

  • So as you can see if you're familiar with these common keypad locks, bypassing them is a fairly simple task.

  • In any case, that's all I have for you today.
