EEVblog #762 - How Secure Are Electronic Safe Locks

How secure are electronic locks used on safes? Part 3 is where I show 5 ways to crack into a cheap safe! Dave tries a basic first attempt power line analysis attack on a standard La Gard (LG) 3740/3750 Basic electronic digital lock on a CMI home safe. Can you crack an electronic digital safe lock with just a resistor and an oscilloscope? All sorts of safe cracking techniques are discussed - thermal camera imaging, bumping, drilling, and spiking the solenoid. And naturally there is a complete teardown of the La Gard lock and a demonstration on how it works. And then Dave does something incredibly dumb, and has to fix it the old fashioned way, Hollywood style. It’s a tail of epic fails and stunning wins.
