[1045] Swiss Army Knife Bypass of Keypad Lock

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 or the correct code is entered from the outside that code is currently one two three four now bypassing 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 paperclip 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 are 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 keychain 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 play 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 ok I've hooked that spring now I'm going to fold the paper clip over and that should allow me to remove these screws without any fear of an alarm going off okay now that I flipped 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 bridge 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 bridge it 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 if you do have any questions or comments about this please put them below if you like this video and would like to see more like it please subscribe and as always have a nice day thank you

Any system that checks for the code on the OUTSIDE is easy to overcome. It's a terrible way of doing things. The check should be on the inside and only the numbers (+electricity) should pass the cables. It's basically entering without leaving a trace and non-destructively made easy. I'm surprised that there aren't more thefts due them or that insurances don't demand a in-house check, instead of outside.

On the device we have we can also quickly reset the device letting you in with your own code and blocking any else out as the old codes don't work anymore.

His video's always entertain; short, educational and to the point but also laughable because how bad some of these manufacturers are.

Well, now I am going to have to tell my boss that his building is no longer secure. Also, I will charge him for my consultation on purchasing a new system.

So if the cover plate and housing were made of plastic it wouldn’t bridge. Also, may help if the screws weren’t Philips head, hex maybe?

Everything can be hacked with enough determination. People don't realize that, at best, most of these systems are designed to slow people down. If someone really wants to get in, they will.

Good job

In the real world I've never seen one of those used with an egress button. It's not needed on that type of lock

His videos are informative, but I find he misrepresents the purposes of the locks. Locks are often to simply deter the opportunist or random stranger. Nobody is installing these locks on bank safes.

He wouldn't have had such an easy time if the box had the weather proof seal on it and if the egress button was wired to the power supply
