KitchenAid Built-In Microwave Message Locked, Lock or Loc: Unlock the control and door

What Locked, Lock or Loc means

On KitchenAid built-in microwaves and combination microwave-wall ovens like the KMBP100ESS or KOCE500ESS, Locked, Lock or Loc means the Control Lock is active. It shuts down the panel controls to avoid unintended use. While the panel is locked, none of the controls will function. Unlock the oven control and, where the model has one, the door. It is easy to trigger by holding a key too long.

Common causes of Locked, Lock or Loc

Control Lock turned on from the panel
Door lock engaged together with the control lock
Keys held down by accident

✓ One safe check you can try

1. Find the lock or unlock instruction on your control panel, usually a press-and-hold on a key. 2. Hold it until the message disappears. 3. Try opening the door and then start a short test. 4. If the message stays and the keys do not respond, reset the breaker for a minute and call us if it persists.

! Why to stop there

The lock is a safety feature and not a defect.
If it will not release, the keypad or control needs attention.
We quote in writing before any repair.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.
