Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
Had a 4 pin code (rotating code system) for many years. suddenly, the door will open or close as soon as i push any number on the key pad. i tried reprogramming this wireless key pad by 1) pushing down the orange learning button on the lift 2) and entering a code within 30 sec on the key pad. didnt work. ONe issue is that after i enter the 4 number PIN, i realize there is no "enter" button on the key pad so i dont know if how i originally programmed it 5 yrs ago.
You are using a universal keypad and usually the 0 button is "enter" look up directions for the brand keypad you are using

Tips for a great answer:
the smart/learn button on the rear of the motor unit near where all
those white wires go. Press and immediately release this and then
walk over to the keypad and key in any 4 digit code you like and
If it is hardwired do this:
To program the keypad,
first unplug the garage door opener from the electrical outlet. Next,
remove the nameplate from the console that the keypad plugs into and
locate the program/operate switch. Flip the switch to program. Next,
enter your desired four-digit PIN number into the keypad. Slide the
switch back to operate and plug the garage door opener back in. The
keypad should be programmed.
