Symptoms
- Key goes in but won't rotate
- Key turns partway and stops
- Lock feels gritty or stiff
- Drawer may not be perfectly aligned or closed
Likely causes
- CommonDebris or grime inside the lock cylinderKitchen grease and dust can accumulate in the small lock mechanism over time.
- CommonDrawer not fully aligned or closedSome models mechanically prevent the key from turning unless the drawer is properly seated.
- PossibleWorn or bent keyA worn key won't engage the pins correctly, mimicking a stuck lock.
- PossibleFailing lock cylinderThe internal lock mechanism itself can wear out or break after years of use.
What to do
- Make sure the drawer is pushed in fully and evenly before trying the key again.
- Try a light application of a dry lubricant like graphite spray into the keyhole rather than an oil-based product, which attracts more grime.
- Test with a spare key if you have one, to rule out a worn or bent original key.
- Wiggle the key gently while applying slight turning pressure, which can help if pins are just slightly sticky.
- If the lock cylinder itself seems to be failing, plan to have it replaced, since forcing it can break the key off inside.
Tools and parts
- Dry (graphite) lubricant spray

When to call a pro
Call an appliance technician if the key still won't turn after lubrication, since forcing a stuck lock can snap the key off inside.
