I have a Liftmaster garage door with an external wireless keypad (model 66LM). The keypads that you can buy are of similar quality to the pushbuttons that come with garage doors... in other words, garbage. My keypad lasts about 1-2 years + the battery (A23) is short lived as well. I am tired of dropping $30+ every few years for a device whose buttons occasionally work.
Has anyone used and/or discovered a remote keypad that works 100% of the time? I can also hard-wire the keypad if required.
