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

1 Answer

Both remotes work intermittently. Batteries have been replaced in both of them but problem still exists. They will work fine when I am within 5 feet of the main unit but otherwise I have to keep pressing the button until the remote eventually works. I tried reprogramming them too, did not solve the problem.

If two remotes have exactly the same problem then it must be the receiver. It is part of the logic board.

Samsung DVD-V3650 - Remote operation (on/off, single frame) is intermittent. Batteries are fine...


The issue maybe the board in the players. Wipe the front to make sure the IR sensor isn't being blocked by a smudge, and if it still is intermittent you can try replacing the remote from the manufacturer. If both don't work the unit will need to be replaced if the intermittent working on/off is too much to bear :)

2002 bmw 530i key does not (remotely) unlock doors or trunk but they work fine manually.


Unlock vehicle. Enter vehicle. Close driver's door. Switch ignition ON and OFF. Remove ignition key. Press and hold unlock button. Press lock button briefly 3 times within 10 seconds keeping unlock button depressed. Release unlock button. Some models: LED flashes slowly for 10 seconds. Some models: Central locking system locks and unlocks rapidly to indicate correct programming. Repeat above procedure if central locking system does not work and LED does not flash or LED flashes continuously.

Intermittent remote trouble


Your wall control is hard wired and doesn't use the receiver portion of the logic board. The remotes do. Your receiver is going bad.

Remote hardly works.

Have you replaced the batteries in the remote with fresh batteries? If you have, then you may have IR interference that may be causing the intermittent loss of function on your remote. Try turning all components off, including any lights, to see if the remote works. If it does work, turn 1 component on at a time and trying the remote to see if it works. If the remote doesn't work after turning a component on, that is probably what is causing the problem. If it still doesn't work after turning all components on, you may need a new remote. I hope this helps.

Elecrtonic ign. sw. switches on intermittantly. can it be repaired or must it be replaced? If you wipe the key front with a damp cloth it starts the motor immediatly


Try replacing the batteries in the key. Does the remote central locking work o.k. The switches themselves do fail and you must replace them. The only other item that can be faulty is the immobilizer ring wich reads the key signal and sends it to the switch. I would clean the key lens and replace the batteries. If problem still exists replace the immobilizer ring. These type of problems can be expensive to diagnose.

Keyless remote does not work after replacing batteries


I had the same problem and located the addendum to the owners manual. It's kind of overcomplicated it seems. Here is what it says:
1) Confirm all doors are closed and the key is out of the ignition.
2) Open the driver's door and put the key in the ignition within 10 seconds.
3) Remove the key within 10 seconds.
4) Push and release the driver's door switch 3 times within 20 seconds.
5) Insert the ingition key within 10 seconds.
6) remove the ignition key within 10 seconds
7) press and hold both "lock" and "unlock" on the transmitter for more than 5 seconds within 20 seconds of removing the key All doors will lock/unlock to confirm the process has been properly done.
8) Press "lock" or "unlock" on the transmitter within 5 seconds of completing step 7. All the doors will lock/unlock to confirm that the process was properly done.
At this point the transmitter has been properly programmed.

Of course, this didn't help me. My transmitter still does not work. I did confirm the procedure with a known good transmitter, so it is valid. If the lock/unlock does not happen in step 7, you more than likely have a bad transmitter.

Vizio 50 inch plasma -- remote not working


You can also try to take out the batteries and push all of the buttons with the batteries out of the remote. Then put the batteries back in and push the power button on the remote. If this doesnt work press the two TV buttons at the same time and the remote should be fine.
