How to Remove a Broken Key from Your Car Lock

Ooops, your car key has snapped inside the lock! What should you do now? The best course of action is to contact a professional locksmith. They have the tools and expertise to safely remove the broken key with minimal risk of damaging the car door lock. However, if you’re determined to try solving the problem on your own first, here are a few methods using common household items that might help you extract the key fragment.

Align the Cylinders

If the key broke while turning the lock, it may still be stuck in a partially turned position, making removal more difficult. To fix this, use needle-nose pliers to gently rotate the lock cylinder to either the fully locked or unlocked position. Avoid pushing the key further into the lock or twisting it, as this could worsen the situation. Once aligned, try gripping the broken key fragment with the pliers and pulling it straight out.

Use Tweezers

Tweezers can also help, but you need to ensure they’re the correct thickness. They should be thin enough to fit alongside the key but not so thick that they push the fragment further in. Open the tweezers wide enough to grip the key and carefully pull it out. Be patient and precise with this method.

LUBRICATE THE LOCK

Applying a lubricant to the lock can make it easier to slide the key fragment out. Use an oil-based lubricant like WD-40 if that’s what you have on hand, but professionals typically recommend dry lubricants because they prevent grime buildup over time. After spraying the lubricant into the keyhole, wipe away any excess before you proceed. Note: If you plan to use glue or sticky putty, avoid lubricants as they may prevent these methods from working effectively.

Try the “Probe and Pull” 

This method involves using two thin pieces of metal, such as a bobby pin or paper clip, to carefully grip the sides of the broken key. Insert the metal pieces into the lock on either side of the key fragment, just enough to catch a firm hold, and gently pull it out. It might take a few tries, as you could lose grip, but persistence can pay off. Avoid using any valuable items for this, as they may bend during the process.

Extract with Paperclip

Straighten a paperclip and insert it slightly above the broken key fragment. Twist the paperclip downward to hook behind the key, then pull it out in one motion. This simple technique can be effective if the key isn’t lodged too deeply.

Use sticky putty 

If you have access to sticky or tacky putty, it can be a useful tool. Press the putty into the keyhole, ensuring it contacts the broken key fragment. After letting it sit for a few minutes to create a good bond, carefully pull the putty out. If successful, the key fragment will come out with it.

When to Call a Locksmith

If none of these methods work or you don’t have the right tools on hand, it’s best to contact an auto locksmith. Attempting rough methods or using adhesives like super glue could damage the lock further, leading to higher repair costs. A professional will ensure the broken key is removed quickly and without harming your vehicle.

By trying these gentle methods, you might be able to resolve the issue yourself. However, sometimes the safest and most efficient solution is leaving it to the experts.
