The problem lies where the electronic part of the keypad is. The connection may be loose or there is moisture damage that has corrupted the keypad input. When you replaced the keypad, did you just replace the buttons or the actual pad itself?

If your external keyboard works fine then it is most likely your laptop keypad problem. otherwise the replaced mobo has problem in its keypad connector point. was it a repaired mobo or completely new one?

The down button the numbers 2, 3 and end call button have stopped working. when i press one of these buttons its shutting the phone down-any ideas or advice please?


Hi, it's the keypad IC or the keypad itself. So you can check the keypad if there is dirts that is stopping the keypad from working. Or the keypad needs to be replaced.

After checking the keypad if the keypad still did not solve the problem,
You will have to replace the keypad IC inside the board of the phone.

Take care. .

Our liftmaster keypad doesnt open the door when code is pushed in unless you press hard. Does it need replacement? Battery was changed


Yes the buttons are worn out. Make sure you get the same model number. There are some that look alike but will not work properly.

Three numbers on my phone keypad not working.


You need to remove the external casing and replace the keypad inside.

The operation can be done while you are waiting at any Phone shop with parts and repair facility.
