Must the lock be replaced after extraction?

Not always. If extraction is clean and the mechanism works normally, the lock can stay. If the cylinder shows heavy wear, preventive replacement is recommended.

Why keys break in locks

KEY TAKEAWAY

Broken key stuck in your lock in Paris? The right reflexes, mistakes to avoid, and how a locksmith extracts the fragment without damaging your door.

Worn or bent keys, dirty or stiff cylinders, poor-quality copies, and misaligned strikes that force you to twist hard all weaken the metal. Paris winter can make mechanisms stiffer and increase the risk.

What to do — and what to avoid

Stop moving the lock immediately. Further turning often pushes the fragment deeper.

If a piece sticks out, fine tweezers may work — gently.

Never:

✓Push with screwdrivers or pins (may jam the mechanism)
✓Use superglue on a tool (can glue the whole lock)
✓Force the door if the fragment is engaged in the bolt
✓Call an unverified “cheap” emergency number
