Common fix for keyless entry remote

Wireless remotes for cars get a lot of use. When they stop working the first response is usually to change the battery. But what do you do after you change the batter and it still isn't working? Many wireless remotes have carbon contacts on the back of their rubber buttons that complete the circuit when the button is pressed. This carbon can degrade and leave buildup on the copper connection of the circuit board. This buildup of carbon will cause the buttons to become unresponsive. This is probably the second most common reason your wireless remote isn't working.
You can easily fix this by taking the remote apart. Most will separate into two pieces and can be popped apart with a flat head screw driver or even a dime. Lift the rubber buttons off of the circuit board to reveal the gunked up contacts. You can clean the contacts with nail polish remover (acetone) or rubbing alcohol but the best solution to use is tape head cleaner which contains xylene. Dip a cotton swab in the solvent and scrub the copper contacts with it until the are clean. Reassemble the remote and try it out.

The remote control has simply stopped working! The batteries have been changed! Nothing on the remote is accepted by the TV. There is no response, not even a flicker from the TV.


Hi there,

Try resetting your remote:

* Remove batteries
* Press each button on your remote, twice. (one button at a time). This should discharge any current left in the capacitors.
* Insert fresh batteries.

If the above fails, then your remote is faulty.

My car remote won't work... sometimes! (I think it's also referred to as a "fob"?) A lot of times I find myself repeatedly pressing the buttons (lock, unlock, set alarm, and open trunk) for my car, but it won't work. I'll try taking a couple steps back, walk around the car, point the remote at the car from high in the air... just some silly things to try and get it to work. I've also tried changing the battery and this just doesn't help. I have 2 of the same remote (2009 Chevy - with remote start) that I bought brand new online and had a car dealership program for me. One remote was for back-up in case the other one stopped working, like the one that came with the car. The first worked fine for a couple of months and now it's just frustrating to try and lock/unlock my car with them. I opened the second one and it works just as good as the first one... HORRIBLY! Like I said, I have tried changing the batteries, (ensuring it's the correct battery, of course) however it doesn't seem right for the battery to deplete in such a short time. Usually after a couple minutes of trying, the remote will magically work. However, after I got off work last night I spent about 10 minutes trying to get my remote to work and finally gave up (this was with second remote that I just opened about 4 days ago). My car alarm was going off and I couldn't stop it because my remote won't work! I've had enough of these games... please help me! I've only owned this car since July 2010. The remotes started acting up about 3 months after I got it. Do you have any ideas as to what the problem may be? Should I take my car in and get the receiver looked at?


A 2009 should still be covered under warranty! Take it back to the dealer, the reciever is having issues.
