Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
We have 1/2 HP Craftsman Garage opener. Our keyless entry won't open when using the codes but it will close when using the codes. (if the garage was already open and I need to close it on the outside, it would close. but if its already close and use the keyless entry to open the door, it wont open) Can you please help me with this?? We have checked the sensor, batteries and all was working just fine as it works from car remotes, inside control console etc.. Thank you

What you are asking for is not possible. You need to call a garage door repair technician. They will drill a hole through the door and using a special tool can pull the rope to release the door.

Sounds like your receiver which is part of the logic board has quit. The wall control is hard wired and doesn't use the receiver.

The remotes and keypad use the receiver which is part of the logic board.'t The button on the wall is hardwired and doesn't use the receiver. You might pull the logic board and check for bad connections on the printed circuit.

If both units were manufactured before April 2005 or both were manufactured after that date they should work. If one is older and the other newer than that date they will not work with each other.
