Garage Door Keypad not working? Easy fix. Lets also make it brighter

In this video we tear down and repair my garage door keypad.
The buttons no longer work because they are worn out.
I will show you an easy fix that you can do for FREE!

Also, the keypad lights up when you press a button but it's very dim. I will
replace the LED's with brighter ones. We also go over how the circuit works using a schematic that I found online.

This fix will work for Liftmaster, Chaimberlan, Craftsman and just about any other garage door keypad.

UPDATE:
I had to redo this using aluminum foil tape. The glue did not hold the regular foil in place. After a few months it started coming off for a couple of the keys. The aluminum tape has been working great so far.
