Electrolux Microwave Error Code LOCKED

LOCKED means the Child Lock feature is active and the control panel has been intentionally deactivated. The microwave will display this message whenever any pad is touched while Child Lock is engaged. This is not a malfunction or error. It is a built-in safety mode designed to prevent unintended operation.

The microwave is not operating while LOCKED is displayed, so there is no active safety hazard. The appliance is simply in a locked state and will not heat food or run any cycle until Child Lock is deactivated. Once you enter the unlock sequence, the microwave returns to normal operation.

In the vast majority of cases, there is no repair cost at all since LOCKED simply means Child Lock is active and is resolved with a key sequence. If a damaged membrane keypad is preventing the unlock sequence from working, keypad replacement parts typically range from $20 to $60, with professional labor adding $75 to $150 depending on your area. Control board replacement, if needed, is a more expensive repair in the range of $100 to $250 for parts alone.

To clear the LOCKED message, touch the User Pref pad and then immediately touch the Start/Add 30 Sec pad. This two-step sequence deactivates Child Lock and restores normal control panel function. No tools, parts, or service technician are needed to resolve this condition.

Unplugging the microwave and restoring power may clear Child Lock on some units, but this is not the recommended or reliable method. The correct approach is to use the designated key sequence: User Pref pad followed by the Start/Add 30 Sec pad. Using the proper unlock sequence ensures the feature is fully deactivated.
