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?
I understand that Chamberlain is the manufacturer and they manufacture
several models that are rebranded such as Craftsman. If it needs
replacement, is it recommended that I buy a LiftMaster branded one or
can I goto a home improvement store or Sears and pick one up and know
that it will work?
Thanks in advance.
If not hardwired...
The master unit will need to 'learn' the remote, otherwise anybody could
just walk up with one and open the door.
See if the master doesn't have a switch marked 'learn' or something like
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 understand that Chamberlain is the manufacturer and they
If you have a Menards Home Improvement where you live, they sell
"Clicker Wireless Keyless" keypads that are compatible
with Liftmaster and others. I've had one for several years. I'd guess
I spent about $20 for it.
Thanks for the replies. I will investigate further.
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.

Before replacing you should determine if it is defective or just needs
to be programmed which can be done easily w/ a helper. Locate the
L.E.D. light next to the "smart button" (programming button) on the
motor head near the antenna wire (may need to remove a lens cover to
see clearly)and follow a few steps.
Please note: If you have close neighbors & 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 & 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.
1) Watch the LED light while the helper enters the current code &
pushes enter. If the LED flickers the keypad probably just needs to be
reprogrammed. Push the smart button momentarily & release, have helper
enter code & push enter before the LED light goes out in 30 seconds.
(Holding the smart button until LED goes out erases all code &
transmitter memory). Test keypad.
2) If LED doesn't flicker when current code is entered have helper
punch in any code without using any of the same number keys as old
code (some or all of the current number buttons may be worn out). If
LED flickers, program in a new code by using different numbers. Test
Keypad. (Entering a new keyless code will automatically erase the old
3) If LED doesn't flicker at all during step 1 or 2 replace keypad.
Yes you can use a Liftmaster, Chamberlain, or Craftsman keypad at long
as it is rolling code (Security+) compatible. Other brands that say
they will work w/ many brands are not always rolling code compatible &
will not work w/ your unit. The Liftmaster keypad is a 976LM, I don't
know the Chamberlain & Craftsman numbers off hand.
