Medford Lock Tip: What to Do If Your Key Breaks Inside the Lock

A broken key inside a lock is a stressful problem, but the first few seconds matter. The biggest mistake is trying to force the remaining part of the key or pushing tools into the cylinder without knowing where the broken piece is stuck.

In many cases, a key breaks because it was already worn, bent, weak, or being used in a lock that needed adjustment. Older exterior locks can also become harder to operate over time, especially when the cylinder is dirty or the door is slightly misaligned.

• Do not keep turning the broken key fragment.
• Avoid using glue inside the lock. It can damage the cylinder.
• If part of the key is visible, do not pull aggressively. The piece can snap deeper inside.
• Check whether another entrance is safely available before forcing anything.
• If the key broke because the lock felt stiff, the lock should be inspected before another key is used.

A professional locksmith can remove the broken key, inspect the lock, and help determine whether the lock can stay in place, should be rekeyed, or needs replacement. This approach can help prevent extra damage and avoid turning a small problem into a bigger repair.
