How to Fix a Key Fob That isn't Working

If your key fob won't work, you can fix it with some simple steps. First, make sure that it's not your backup remote.

If your backup remote cannot lock and unlock the doors of your vehicle, it is likely that the primary remote is not working. The majority of car remote key malfunctions are caused by circuitry or battery issues.

Battery

If changing the battery doesn't fix the problem there could be other issues that require professional attention. For instance, if buttons seem to be stuck or broken It may be necessary to disassemble the remote and rebuild its components. It is also possible to reprogramme the vehicle to recognize the new remote.

First, ensure that the batteries are up correctly and that the indentation on the back of the button is filled. Then, carefully open up the remote and inspect the circuit board. Look for indications of rust or other indications that the buttons have been damaged or worn. For example there could be conductive paint missing. Utilizing a Q-tip dipped in alcohol, gently clean any membrane contacts that are worn or where conductive paint is missing. Avoid rubbing too hard, because this could damage the conductive paint and stop the button firing when it is pressed.

Check the battery connector's terminals for loose solder connections. If this is the case, simply reconnecting them could bring back function to the button. You can follow the same process to restore functionality to any other loose connection within the fob.

If any of the rubber buttons on the front of the keyfob isn't working or need to be press extremely hard the graphite disks on the back of the button could have worn out and need to replaced. This can usually be done by rubbing a pencil over the disks, which should bring the button back to its original state.

If all of this doesn't help, or if the button still does not respond to a hard push, then it may be that the circuit board itself has gone bad. It is possible to fix this by a quick clean, and replacing the solder, but it is best to have an extra fob in case this method fails for you.

Non-Remote transponder chips

Sealed non-remote transponder chip are more durable than the remote fobs they are contained in, however they are still susceptible to being cracked by a hole drilled into them or run over by a lawnmowers blade or car door handle. Fuse failures are usually to blame for non-remote chip failures.

If you're not comfortable opening the key fob, take the circuit board off and use a multimeter to check that the diode is working properly. If you're not comfortable with this, visit your local Oreilly or hardware store and utilize their RF frequency tester. This will tell you whether the key fob sends signals.

Programming
