This button repair works in most rubber keypad contact switches to restore like-new button function
Does not work for snap-dome metal switches
If your keypad is made with rubber contacts for the switch (with or without plastic key caps) this is what you need to restore function permanently. BUT since there are countless designs of rubber buttons there may be some that are too tightly packed or unusual construction that do not allow a universal button to operate properly.  If this does not work for what you need - LET ME KNOW! I will do my best to help you and if we can solve it, the solution can be added to the product line.
