You’re not going to be a master locksmith after you watch this video showing you three ways to break open a lock, but you might stop putting your faith in cheap padlocks. That’s because a few bent paperclips could jimmy the thing open. Even just jamming a screwdriver into the keyhole can make it unlock. Or if you’re super experimental, you can trace a key using tape and then cut out its shape on a flimsy metal can.
That last one requires you access to the key itself but hey, it works!
