Note to all heist movie directors: no need to show someone hacking a fingerprint or keypad lock. Just use a magnet.

LMAO
That's just sad.

It really is when you consider that they could easily have designed it without a relay. That's just lazy design.

Couldn't the relay be moved from the reader inside where it couldn't be accessed?

Sure, although one smart thing to do it is to replace the relay with a solid state device like a triac. They sell devices called "solid state relays" which function exactly like a relay except the input is an opto isolator and the output is a triac.

Exactly this. Makes me wonder how many other types of access control devices can be defeated in the same manor.

And to Err's point, many of these locks need to move the electronics inside. This guy has also opened these things by cracking open the fingerprint reader and using a paper clip to jump power to the selenoid. Takes more work and time, but still a fairly easy bypass. These things just aren't designed with security in mind.

Most electronic safes have the same problem. You can remove the keypad and just send some current down the selenoid wires.
