Child locks on microwaves act as a safety feature to prevent children from getting harmed or from causing other possible damage. The child safety lock does not lock access to the microwave; it simply prevents the microwave from being operated. To remove the child lock press the Stop button three times.

Lock the microwaveIf you wish to re-lock the microwave, perform a similar procedure. Instead of pressing the Stop button you need to press the Start button. Press the Start button three consecutive times to lock the microwave. This enables the child lock once again and prevents the microwave from being operated.

How do you remove the child lock on microwave

If you could post a picture of your touch control that would be very helpful. There are usually two keys you need to press and hold to unlock the child safety. or a model number would be good too.

I don't know the exact model of your microwave.. but this might help you..

You might have set the child's safety lock by accident by pressing the START button three times in a row. To unlock the child's safety lock, press the STOP/RESET three times in a row. Hope this helps.

This is from the 1100ST manual:

CHILD SAFETY LOCK

The safety lock prevents unwanted oven operation such as by small children.

To set, press and hold STOP/CLEAR for 3 seconds, LOCK indicator lights.
To cancel, press and hold STOP/CLEAR for 3 seconds, LOCK indicator goes off.

Does Panasonic microwave NN-T945SF has child safety lock

You can download your Panasonic owner's manual here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Not sure of the TT series models but for the NN series models the procedure is as follows:-

If "Child" is displayed in the display window, then the child safety lock is on.

To remove the child safey lock, press the "Stop/Reset" button 3 times in fairly short succession (less than 3 seconds). The time of day or just the Colon sign (:) is then displayed

If you later want to apply the Child safety lock, then, when the time of day (or colon sign) is displayed, press "Start" 3 times (again in short succession).

Hope this helps

i'm assuming that you don't have the manual. The unlocking procedure should be in the manual. Models with a child lock-out safety feature should have a "Help" button that will lead to an un-lock procedure or a special button that you need to hold for 5 seconds. Try holding down the "0" button or "Start" button for 5 seconds.
