This simple trick could save you time and money!

Few things are more frustrating than having your key snap inside a lock. One moment you are trying to open the door, and the next, half the key is stuck inside while the other half remains in your hand. Most people immediately think about calling a locksmith, but that can be very expensive and often unnecessary. In many cases, you can remove the broken key yourself using a few simple tricks and tools you probably already have at home.

Locksmith

A locksmith can usually solve the problem in minutes, but the price is often surprisingly high. If it happens at night, during a weekend, or on a holiday, the cost can rise to hundreds of euros. And somehow, keys always seem to break at the worst possible moment. Thankfully, there are a few clever methods that can help you remove the broken key on your own and avoid paying a huge bill.

Broken Key

If part of the broken key is still sticking out of the lock, you are in luck. Start by spraying a little oil or WD 40 into the lock. WD 40 works especially well because the thin nozzle helps you spray directly around the stuck key. Apply the lubricant carefully between the key and the lock cylinder. Do not be afraid to use a generous amount. Once the lock is properly lubricated, grab a pair of pliers and gently pull on the visible part of the key. In many cases, the key will slide right out.

Too Deep

Sometimes the key breaks so far inside the lock that you cannot grab it with your fingers or pliers.
If that happens, do not panic. You can try using a strong magnet to pull the broken piece out. If you do not have a magnet, a pair of tweezers or even a straightened paperclip may also work. Another clever trick involves using the other half of the broken key. Add a tiny amount of glue to the broken edge, carefully insert it back into the lock, and connect it to the stuck piece. After the glue dries, slowly pull the key back out. If none of these methods work, there is still one more option you can try.
