If you have one of these safes at home, then your valuables may be protected from fire, but they aren’t safe from a thief carrying a magnet in a sock. It may be worth investing in a new safe, dependent of course on the value of what you are keeping inside.
case in point is the electronic sentry safes you can buy at most retailers for around $250. In the video below, Terry manages to open one in just a few seconds using a rare earth magnet in a sock. The fault? The manufacturers used a nickel solenoid in the locking mechanism.
