Stop turning the lock
More force usually wedges the broken part tighter and can damage the cylinder or internal mechanism.
Forcing a broken key deeper into the lock can turn a simple extraction into a bigger repair. The safest next step depends on how much key is visible, how the lock felt before it snapped, and whether you are locked out.
The main goal at this stage is simple. Keep the lock salvageable if possible. A gentle, informed approach gives the best chance of extraction without turning the job into a full replacement.

If you are locked out, the door is your only exit, or the lock already felt rough, early help usually saves time and stress.
