How to Get a Broken Key Out of a Lock (With Tools You Already Have)
Don’t let a broken key keep you stuck with these at-home tricks
When you’re in a rush (or even if you’re not), there’s nothing more frustrating than when your key won’t turn in your lock. Then to make the situation even worse, your key breaks in the lock and you’re stuck wondering what to do.
In this article, we’ll cover a few tricks for removing a broken key from a lock on your own and who to call if it simply won’t come out.
Why Would My Key Break In The First Place?
Most keys are made out of semi-hard metals, like brass or nickel, that wear out over time. Once you start noticing that your key is sticking in the lock or the edges are becoming dull, it’s time to get a new key made before it’s too late.
But the type of door lock you have could also be the culprit. The lock mechanisms may be failing, or the keyway may need lubrication. Or, if the lock was installed incorrectly in the first place, you may have to use too much force to turn the key—causing the key to break down faster.
How to Lubricate The Lock
Lubricating your keyway is one of the best ways to prolong the lifetime of your keys and locks. Once you notice your key starting to stick or your lock not turning as effortlessly as it should (or if your key is already stuck in the keyway), grab a can of Teflon-based dry lubricant and follow these steps:
Stick the straw into the keyway
Spray a decent amount of lubricant into the hole
Insert your key
Turn it a few times. This ensures the entire lock mechanism is coated in the lubricant
Remove your key and wipe off any residue
Once the keyway is dry, it’s ready to use.
Note: While you may be tempted to use regular WD-40, most locksmiths recommend the dry lubricant to avoid dust and dirt build-up that comes with regular WD-40. You can find a dry version of this product that can work for your needs, though.
How to Get a Broken Key Out of a Lock
Before you call a locksmith, try these ways to get a broken key out of a lock. We recommend lubricating your lock before attempting any of these methods to help your key unstick more easily.
Needle Nose Pliers or Tweezers
Grab the end of the key that’s protruding from the lock
Apply firm pressure to ensure a tight grip
Rotate the key until it’s vertical
Gently wiggle the key out of the lock
Paperclips or Hair Pins
Straighten the paperclip or bobby pin
Insert into the lock alongside the broken key
Wiggle the pin around and attempt to hook it onto the key
Once you feel it latch, pull the paperclip out slowly
If the key doesn’t come out with the clip, try again
Key Extractor
Ensure lock is either completely vertical or horizontal
Slide the key extractor into the keyway with the hook facing upward
Pull the tool straight out
Repeat until the key is removed
Jigsaw
Cut a jigsaw blade horizontally so it fits into the keyway (do not cut off the serrated ends)
Cover the broken edge with duct tape to ensure you don’t get cut
Insert broken blade into the keyway
Twist slightly to gain leverage
Pull the jigsaw out of the keyway
Repeat until the key is removed
Hot Glue Stick
Hold one end of a hot glue stick to a flame
Press the melted end to the broken key
Wait two minutes until the glue hardens
Slowly pull the glue stick out
Taking Care of Your Locks
The best way to ensure your key doesn’t break in a lock is to take care of the lock regularly. While a door lock may fall pretty far down on your homeowner’s maintenance to-do list, it’s still something to look after—especially if you notice it’s getting harder to turn your key or lock your deadbolt.
Here are a few ways to look after your door locks:
Lubricate the lock regularly.
Ensure the door isn’t sagging and put undue pressure on the lock mechanism.
Don’t force a key to turn. Instead, try lubricating the lock or adjusting the mechanism to ensure a seamless entry and exit.
Replace your keys once they start to wear out. Damaged or worn-out keys can put pressure on the wrong parts of your lock system, causing it to break (and possibly breaking your key along with it).
DIY vs. Hiring a Pro
Because you likely already have a few of the tools listed above at home, it’s worth trying to extract a broken key on your own. And even if you don’t, these tools only cost between $5 to $15. But, if you want to bypass the hassle of purchasing new tools or simply want to ensure the job is done right without any headache or effort, you can hire a locksmith instead.
If you go this route, be ready to shell out quite a bit of extra money. On average, the cost of hiring a locksmith runs between $163, depending on the situation. Depending on the provider, you could pay as little as $50 to extract a key, but it could also reach upward of $200 or more if it’s an emergency call.
But, at least you know the job will be done right the first time—which can be worth it if you’re locked out of your house.
Frequently Asked Questions
If part of the key is protruding out of the lock, you can use a pair of needle-nosed pliers or tweezers to gently turn the key in the lock to open the door. If the key is fully inserted into the lock, you may also be able to use a key extractor to help turn the key into the unlocked position.
But if the key breaks off halfway into the lock or you simply can’t reach it to help engage the unlocking mechanisms, you should probably call a professional.
First thing first: Make sure you’re using the right key. If it’s the correct key for your lock, there are a few reasons why it may not be working, like the key is worn out or the lock is jammed. Try lubricating the lock and pushing the door closed to ensure the mechanisms work correctly. If you’re still locked out, call in for help.
In general, keyless door locks are considered safe. They can’t be picked like a traditional lock, and unless a thief can guess your code, it’s pretty tricky to break into a house with a keyless door lock. But that doesn’t mean they come without risk.
When asking yourself, "Are keyless door locks safe?” consider the style of the system. Hackers could potentially break in if it operates on Wi-Fi, but it’d take some time and effort. You’re also at risk for a power outage, depending on the type of lock. That being said, there are no more risks associated with keyless door locks than a traditional lock.
