The keypads on our alarm have become unresponsive on the buttons we’re always pressing. Some keypads work by having the button complete an electrical circuit. You can test whatever keypad you’re working with by opening it up and touching the button contact with a piece of aluminum foil. If it activates the button, you can glue a piece of aluminum foil over the back of the keypad over the worn-out activator. Use clear fingernail polish or krazy glue…and generously apply it. If it works, you don’t have to replace the whole keypad or remote or whatever has worn out.
