My Key Is Stuck in a Deadbolt Lock


Getting a key stuck in a lock is frustrating and can even cause panic in certain situations. There's a reason why your key is stuck. Once you remove the key, take steps to ensure that it doesn't happen again.


  • Remove the two screws from the trim plate and edge plate, then remove the trim. Remove the lock assembly. If it doesn't come out easily, pry it out carefully with a small pry bar.

Key Removal

  • Remove the cylinder retaining screws from the back of the deadbolt, then pull the tailpiece to remove the cylinder. Push a bent safety pin through the back of the cylinder to release the broken key.


  • Submerge the assembly in mineral spirits or turpentine. Put on rubber gloves, and clean the lock with an old toothbrush. Allow it to dry fully, then spray it with a petroleum-based lubricant to prevent the key from sticking in the lock in the future.
