If you just broke your key in the lock to your house or car, there’s no need to panic! With a few household items, you can get back on track in no time. Keys can break if the lock isn’t properly lubricated, the key is twisted or damaged, or the lock has iced over or is jammed with dirt and debris. All you need to do to fix it is spray a lubricant inside the keyhole and use tweezers, a pin, pliers, or even a hot glue stick to remove the key. If the key is still stuck inside, it may be best to call a professional. Keep reading to learn more!

Getting a Broken Key Out of a Lock

Spray the keyhole with a lubricant like WD-40 or graphite powder. Grab the broken end of the key with a pair of pliers, tweezers, or scissors, and pull it out. Alternatively, insert a pin, paper clip, or needle into the space between the lock and the side of the key and pry the key out.

  1. Spray the keyhole with lubricant. Insert a pin into a space between the key and the keyhole. Try to get the tip of the pin into a groove or notch in the key and pry the key out of the hole.[2]
    • If you can’t get enough leverage, use a pair of pliers to bend the tip of your pin and use the tip to grab the side of the key.[3]
    • Once the key is partially out of the lock, use a pair of tweezers or pliers to grab the end and pull it all the way out.
    • Alternatively, use a paper clip or a sewing needle. You can also a fish hook.[4]

Hot Glue Stick

  1. Use a lighter to melt the end of the hot glue stick. Once the tip is melted, press it gently onto the end of the broken key. Wait for 1 to 2 minutes so the glue dries, then slowly pull the stick straight back. The key should come out with it.[7]
    • Alternatively, apply super glue to the end of the key head, clean the edges with a paper towel, then hold the key back together. Let it dry completely, then pull the key out.[8]
    • Try to avoid getting glue inside the lock mechanism. If you do get glue inside, you may need to call a locksmith.

Saw Blade

  1. Spray the keyhole with a lubricant. Use a pair of pliers to break off one end of the jigsaw blade. Slide the broken side of the blade into the space between the lock and the key, twist it slightly, and pull the key and the blade out.[10]
    • Jigsaw blades are made of a brittle metal, which makes them easy to break with a pair of pliers.
    • Cover one end of the blade with duct tape so you have a safe handle to grab onto.
    • Alternatively, try using a barbeque skewer or a bicycle spoke.
    • If the key comes partially out, just grip the end with needle-nose pliers and finish removing the key the rest of the way.

  1. Most modern keys are made of brass, aluminum, or nickel silver.[12] If your key is made of aluminum, you can use a very strong magnet to pull it out. Just spray the keyhole with a lubricant like WD-40, place the magnet onto the end of the broken key, and pull it straight out.
    • Brass isn’t magnetic.[13] Nickel is magnetic, but silver isn’t.[14] Depending on the composition of your key, a magnet might not attract to it.
    • If your key doesn’t pull out with a magnet, try a different method to remove it.

Extractor Tool

  1. Slide a key extractor tool into the lock, turn it, and pull the key out. Spray a silicone lubricant or graphite powder into the keyhole. Master locksmith Shawn Fago says to insert the small hook tool (with the hook facing upward) as far as possible into the lock along one of the grooves on the side of the key. Then, “pull straight out and the key should come out.”
    • If the hook tool doesn’t work, try the spiral style tool. Instead of twisting the tool toward the key, spin the tool’s handle several times before pulling it straight out.
    • If the keyhole is in between the locked and unlocked positions, use needle nose pliers to reach inside the hole and turn it into either position.

  1. If you need to open a door immediately and the other methods don’t work, unscrew the handle.[15] Insert a screwdriver into the center hole in the latch assembly. Push towards the door latch, wiggling back and forth until the door pops open.[16]
    • If your door handle doesn’t have any visible screws, you may have to twist the plate underneath it to expose the screws.[17]
    • If the key is stuck in your car, motorcycle, or a padlock and won’t come out with the other methods, it might be best to call a professional to help instead.

Article SummaryX

To remove a broken key, start by spraying a silicon spray into the lock, which will lubricate it and make it easier for the broken key to slide out. Then, use a pair of needle nosed pliers to twist the cylinder so the lock is either locked or unlocked, since the key part won’t come out if it’s halfway between the 2 positions. Next, select an extractor tool from your set, which you can buy at a hardware store, and slide it into the lock with the hook facing upwards. Try to locate the groove on the side of the broken key, then twist your tool towards the key. Gradually pull the tool out, which will hopefully cause one of the hooks to catch on the broken key’s teeth and pull it out. Remember that you may have to try several extraction tools, since they are all made differently and will perform better depending on the type of lock you have. For tips on how to make your own extracting tool, read on!
