Question:
I am having problems with my garage door keypad. The interior remote
and the other remote controls all work properly. The keypad is the
only problem. I would guesstimate that it is only 6 to 7 years old.
It is a LiftMaster Security+ but I don't have the model number.
I have tested the battery and even replaced it with a brand new
battery and the keypad still does not operate the garage door. The
connectors to the battery are clean. Is the keypad going bad? Can it
be disassembled and cleaned? Or is it just the circuit board for the
keypad just worn out and needs a replacement?
Answer:
Having the manual would help a lot. You may find an on-line manual at
their web site. As Tim said, it is likely that it just lost the code and
you need to re-program it. It may also be defective. In either case you
should be able to buy any make and model that is designed to work with your
garage door opener. The brands do not need to match.
I guess I should have added that it had been working until the past
few weeks. You had to press the keys pretty hard, unlike when it was
first installed when you could just "lightly" press the keys. I did
not think about trying to reprogram it, so I will give that a try. It
could be the keypad is just plain worn out.
If you have close neighbors and if they push their
transmitter while you are doing the steps below, the neighbors
transmitter may cause the LED light on your unit to flicker and you may
need to repeat some of the steps. The LED flickers when it picks up
any signal. The door only opens when it gets an authorized command.
Watch the LED light while the helper enters the current code and
pushes enter. If the LED flickers the keypad probably just needs to be
reprogrammed. Push the smart button momentarily and release, have helper
enter code and push enter before the LED light goes out in 30 seconds.
(Holding the smart button until LED goes out erases all code and
transmitter memory)test keypad.
