A key snapping inside a lock is annoying, but the right approach can save your lock from damage.
Step 1: Stay Calm and Inspect
Look inside the keyway with a flashlight. If part of the key is sticking out, removal is much easier.
Step 2: Add Lubricant
Spray a little graphite powder or lock lubricant into the keyway. Avoid heavy oils, which collect dust and cause jams.
Step 3: Use Needle-Nose Pliers
Grip the exposed end firmly and pull straight out without twisting.
Step 4: Try a Key Extractor
A thin extractor tool can hook the broken piece’s teeth and draw it out gently.
Step 5: Call a Locksmith
If the piece sits deep or will not move, stop. A professional can extract it without harming the lock and cut a new key.
Final Thoughts
Never use glue or force, since they can ruin the lock. Patience, or professional help, keeps repairs small.
