If your Emerson microwave is locked and the buttons are not working, or you want to prevent accidental use, this guide will show you how to turn the child lock feature on or off. These steps work on many Emerson countertop microwave models, including many 700W and 900W models.
How to Turn On Child Lock (Lock the Controls)
Make sure the microwave is in standby mode (the clock is showing).
Press and hold the STOP/CLEAR or STOP/CANCEL button.
Hold the button for about 3 seconds.
The display should show a lock symbol, "LOCK," or the controls will stop responding.
How to Turn Off Child Lock (Unlock the Controls)
Press and hold the STOP/CLEAR or STOP/CANCEL button again.
Hold it for about 3 seconds.
The lock symbol should disappear and the microwave should return to normal operation.
If the Emerson Microwave Will Not Unlock

Try these steps:

Make sure you are holding the button long enough (3–5 seconds).
Press STOP/CLEAR once first, then hold it down.
Unplug the microwave for 1 minute.
Plug it back in and try again.
Make sure the microwave is not currently running a cooking cycle.
Important Note

Most Emerson microwaves use the STOP/CLEAR button for child lock, but some older models may use STOP/CANCEL instead. The exact wording depends on the model.
