What Lock means

On KitchenAid induction cooktops such as the KCIG550JSS, the word Lock on the display means the Control Lock is switched on. The feature is there so nobody starts a surface cooking area by accident, for example a child or a pet. When the lock is engaged while the cooktop has no power, the cooktop stays locked out and no cooking area will heat. The message is informational and does not mean anything is broken.

Common causes of Lock

  • Control Lock switched on deliberately, for cleaning or child safety
  • Control Lock turned on by an accidental key press
  • Lock set before a power outage and still active
  • A lock key that does not respond when you try to release it
✓ One safe check you can try

1. Look at the display and confirm that Lock is showing. 2. Use the lock key sequence for your model to release it. 3. If it will not release, switch the breaker off for a minute and on again. 4. If Lock stays on, call us.

! Why to stop there
  • A lock that cannot be released points to a touchpad problem.
  • The touchpad sits under the glass with live wiring.
  • Our price comes in writing before any work, with 30 days of warranty.
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.

LockLock questions
Why will my cooktop not heat when the display says Lock?

The Control Lock is engaged, which blocks every cooking area on purpose. Nothing heats until you release the lock with the key sequence for your model, so check the display before suspecting a failed part.

Does the lock survive a power outage?

Yes. A lock that was on when power dropped is still on when power returns, and the cooktop starts out locked. Release it the same way you set it, then start your zone as usual.

What if the lock key does nothing?

The key may be dirty, or the touchpad may be failing. Clean the panel, reset power once and try again. If it still does not respond, we should inspect the touchpad.
