Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

2 Answers

Hey, I've got a Craftsman 1/2hp garage door opener circa 1991 that is picking up the signal from my neighbor's remote. Tried resetting the pins a few times and tried leaving it unplugged for a few days to see if it would reset. It didn't... Any thoughts? Next I was gonna try disconnecting wires and see what happens... This all started because I got a replacement remote and the neighbor happened to come home when I was programming it... what luck... Thanks in advance!

Use the instructions to wipe all the remotes and then reprogram them all when your neighbor is not using his remote.

Make sure your neighbor doesn't have a remote with a sticking switch. Often times a person will stick an extra remote in a drawer and then place something on it that holds the button down. Try programming your remotes this way just in case you didn't.

Press and hold the button down on the remote while you press and immediately release the smart/learn button. Sometimes it can help if you are in the garage when you program your remotes this way and it will drown out any distant signal.

Have your neighbor bring over his remote and open or close your door with it. Then hold the smart/learn button in for 6 seconds on your opener. Then see if he can open your door. He shouldn't be able to because that procedure erases the memory in your opener. No remotes should work. You need to get that remote #53778 back and program it and then see if your neighbor can open your door. If he can open your door at any point after you have held that button in for 6 seconds you need to get a new door opener.

It sounds like you have a remote with the button pressed or broken so that it is on all the time. Remove the batteries from your remotes and check that light. The rapid flashing is an indication that it is receiving a signal. Make sure you don't have an old remote in a drawer somewhere.

Garage door is opening when the neighbor open theirs with remot


You say you "setup the remote and the main box but doesn't solve." I think you mean you programmed the unit but I'm not sure. Anyway try holding the smart/learn button in for 10 seconds and this will erase the memory. None of the remotes should work. Now when you are sure the neighbor will not be using their opener, program your remotes. This may be what you did but I'm not sure.

Neighbor opening our garage door


Report this problem to the Manufactuer stating your model number of controller and remotes too and they may help solve your problem faster than getting offside with your neighbour,apart from that the remotes and motor controller may need replacing to give you more security and control over your own secure enviroment,

I have fitted many security devices,alarm panels,cameras,sensors,keypads,etc,
and never had to repair this type of fault as the supplier or manufactuer has always assisted with their products thru warantee or advice,

I have 20 years of experience in the industy in NZ,Thanks MISTERDJ

Garage door opened by neighbor


Have you seen the neighbor open your door? The reason I ask is because it is almost impossible. The most common cause of a door opening by itself is a bad wall control or the wiring leading to it. You can temporarily eliminate both possibilities by removing the wire from terminal 1 at the rear of the motor unit. Do this and ask your neighbor to bring over his remote and try it on your opener.
