For those considering an electronic safe to protect your valuables, think again. This fascinating video shows that if the safe isn’t flush-mounted into a wall or situated in a confined space, it can easily be cracked, with or without any tools (mallet). Continue reading to see how.

As you can see in the video above, you literally drop part of the safe against the table (or whatever surface it’s resting upon) while turning the locking knob. If your timing is right, you’ll have turned the knob when the safe’s lock bounces open for a brief moment. This works because many cheaper safes have locks that lift. Better safes have counterweight mechanisms so the lock is held in place even when the safe is moving. You won’t be able to bounce those open, but you’ll have no problem with the lower-end options. If you’re successful, the deadbolts will recede into the safe’s door and you’ll be able to open it up.
