EEVblog #762 - How Secure Are Electronic Safe Locks?
11,555How secure are electronic locks used on safes?
Part 3 is where I show 5 ways to crack into a cheap safe! https://www.youtube.com/watch?v=Y6cZrieFw-k
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.
