様態の副詞

This is the lock picking lawyer, and I recently found this interesting, unbranded lock on E Bay.

転換語

It's a cam lock like you'd find on a Cabinet or a piece of furniture, but instead of the key, we have an electronic keypad.

程度の副詞

I installed it on this aluminum plate just to make it a little easier to demonstrate.

Once you enter the correct code, the entire keypad operates like a knob, allowing you to turn the cam to the unlocked position.

After a second or two, it automatically re locks.

It's an interesting concept, but unfortunately the designers made a critical error.

The mechanical component that keeps this from rotating when locked is a sullen oId down here in the lower left hand corner that's essentially a small electromagnetic actuator.

And as I've shown you in past videos, if an internal magnet can open the lock, so too can a sufficiently powerful external magnet.

Currently locked, unlocked, locked, unlocked.

So while this is certainly an interesting concept, the execution is deeply flawed, leaving this open to a very fast and very easy bypass.

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.
