There's nothing worse than getting home and breaking your key off in your lock. With a little ingenuity and a few tools, you can retrieve the broken key from your lock. If you don't have access to the tools mentioned, these tools are easy to find at many hardware stores.
Magnet
A magnet may not be the first thing to come to mind to remove a key, but a powerful magnet is capable of extracting a broken key. A small toy magnet won't be enough to make a key budge. You will need a magnet designed to do some heavy lifting.
To remove the key piece, place the magnet over the keyhole of the lock to encourage the key to move toward the magnet. The magnet may not be able to extract the key entirely but should move it closer so that you can retrieve it with pliers.
Gum Eraser
An art gum eraser is almost the same texture as chewing gum. Typically these erasers are small, gray and can be purchased in many craft supply stores. To use a gum eraser to remove a broken key, you'll want the break to be close to the entrance of the lock. Next, knead the eraser in your hand until it's a gummy consistency and then press the eraser against the broken key. Gently form the eraser around the key and then pull. It should remove the key enough to extract it with your fingertips.
Needle Nose Pliers
Needle nose pliers are one of your best bets for removing a broken key. You'll need a pair of pliers that's small enough to fit inside of your lock. Once inside, grip the key with the pliers and extract it. If your key seems to be stuck, spray some oil into the lock to help loosen things up.
Key Extractor
A key extractor is a tool that's a thin metal rod with grooves on it. Simply insert the extractor into the lock and apply upward or downward pressure. This pressure will provide the traction necessary to remove the key. While applying pressure, pull the key toward yourself until you're able to remove it. Key removal tools are inexpensive and available at most hardware stores.
Don't try to force any of the methods, as you don't want to risk damaging the lock. If you've tried everything and the key still won't budge, reach out to a locksmith. A locksmith has a specialized set of tools to remove broken keys and get your home's lock functioning again. To learn more information, reach out to a company such as Roland Park Lock And Key.
