If you've just broken your car key off inside your car door's lock, you're probably a little shocked and unsure what to do. Don't worry! The process for getting the broken key out is pretty simple and will only take you a few minutes. You will need to get a new car key made by a locksmith, though—unless you have a spare.

  1. The removal technique you use depends on how much of the key visible. If some of the key is jutting out of the lock, you’re in luck! You can remove the broken key with a pair of needle nose pliers. [1]
    • If none of the key is sticking out of the lock, use a broken key extractor tool to get it out. The rest of this article will explain how to do it.
  2. If the lock is rotated out of position, use your thumb or a small stiff object to rotate the lock to the insert position. The “insert” position is the position the lock is normally in when you insert your car key. [2]

  3. Grip the key with the pliers and pull it straight out. Resist the urge to turn the key with the pliers as you're pulling it out. You might break the key off inside the lock. [3]
    • As long as there’s enough key protruding to grip with pliers, this should work.
    • If the key isn't budging, try spraying WD-40 into the lock mechanism to loosen it up. [4]
    • If you accidentally break the key off inside the lock, follow the remaining steps to remove it.

  1. If the lock is rotated into some position between the key insertion and operate positions, use your thumb or a small stiff object to rotate the lock to the insert position. [5]
    • The “insert” position is the position the lock is normally in when you insert the key.
  2. A lubricant like WD-40 should do the trick, but you can use special lock lubricant if you happen to have that on hand. Be sure to spray the lubricant liberally and at all angles so it really gets in there and saturates the mechanism. [6]
  3. Choose a tool that is narrow enough to slip into the lock “key way,” which is the straight opening in the lock that extends down from the key opening itself. Make sure the tool you buy has 1 or more hooks on the end that extend upwards to grab the key teeth. [7]
    • You can buy this tool at hardware and automobile parts stores.
  4. Gently insert the key removal tool into the lock “key way.” Turn the hook or hooks sideways while inserting the tool so that they do not catch on the teeth of the key during insertion. Gently jiggle the tool until it won't go in any further. [8]
  5. Slowly and gently pull the tool back, jiggling the tool if necessary, so the hook or hooks engage or grab onto one or more of the key’s teeth.
  6. Use a slow, straight, and smooth motion to pull the tool back. If the key doesn't start coming out of the lock, the hook or hooks didn't catch the teeth properly. [9]
    • If this happens to you, simply pull out the tool and reinsert it into the cylinder just like you did before. Get the hook around the key's teeth and gently pull.
  7. Once enough key is sticking out enough for you to grab it with your fingers or pliers, go ahead and pull it all the way out. [10]

    If you can see the piece of broken key, you are in luck. If you can't, call a locksmith. Hold the dust shutter open with a small object, then use a VERY small drill bit to grasp the key tip and pull it out.
