Sometimes keys can be stuck in the lock. Here's what to do.
Occasionally, keys can stick in the locks for different reasons.
To help remove the "stuck key" try the following:
- Find something like a display peg, screwdriver, or other sturdy object that can be inserted through the keyhole in the key bow to form a t-handle. Be sure not to use another key - too much pressure may bend/break both keys. Gently use the leverage from the inserted object to try to see-saw the key back and forth. Don’t try to turn the key all the way, just try to work it up and down.
- If the key can be retracted partially but is trapped, using the same t-handle, try to rapidly insert and remove the key, “raking” the pins. Occasionally a pin can move inside the core, trapping the key, and this rapid action can reset the pin to correct it.
- If neither of these approaches work, if the key can be partially removed, pull it back as far as it will go, then with a solid sturdy object, strike the back of the key as if it were a nail being hammered into the lock. Be sure to hit the back straight into the lock to avoid the key being bent/broken.
- Finally, check to see if the housing has been tightened down in the incorrect spot. Loosen the top & bottom mounting screws, loosen the set screw and turn the mortise housing to the correct position, then reinstall all removed screws.
