Extract A Broken Key From A Keyhole
Consider yourself lucky if you’ve never had to deal with a key that broke inside the keyhole, halfway into locking/unlocking the door. It does happen more frequently than you think and is a nightmare to deal with—until now.
If you ever become the victim of an unfortunate situation as such, spray some penetrating oil into the hole. With the help of a pair of pliers, get a good grip of the broken key before pulling it out really carefully. This method would be perfect if the key broke at its head. Hopefully, you won’t ever have to face such a dilemma.
