How to Fix a Key Fob That isn't Working

If your key fob doesn't work and you're not sure why, you can fix it by following just a few steps. First, make sure that it's not the backup remote.

If the backup can lock and unlock your car door, then there's a likely issue with the primary remote. The most common causes for key malfunctions for car remotes are circuitry or battery issues.

Battery

Buttons

Key fobs can become filthy and worn out due to repeated use. It is not common for buttons to cease working, or to require a hard press to get them working. This can be very frustrating, especially when you are away from your home and have to turn on your car. Even broken or damaged buttons are often fixable with a little time and tools you already have at home.

First, check that the batteries are properly installed and that the indentation at the back of the button has been filled. Then, carefully remove the remote and inspect the circuit board. Look for evidence of rust, or other indications that the buttons are worn or damaged. For example there could be conductive paint missing. Use a Q-tip that has been dipped in rubbing alcohol to gently clean any membrane contact that has worn out or where conductive painting is missing. Be careful not to rub too hard, because this could damage the conductive paint and block the button firing when pressed.


Also, make sure to inspect the battery connector's terminals to ensure any loose solder connections. If this is the case, soldering them back in place may restore functionality to the button. The same process can be used to restore function to any loose connections in the fob.

In the end, if any of the buttons made of rubber that are on the front of the key fob stop functioning or require a long press to function it is likely the graphite disks on the back of the button are wearing out and need to be replaced. You can do this by rubbing a pencil over the disks. This should bring the button back to life.

The non-remote chips sealed in a sealed case are more durable than their remote fobs, but they are susceptible to breaking in the event of a hole being drilled into them or when a door handle for a car or lawnmowers is pushed over them. The failure of the fuse is usually the cause of non-remote chip failures.

If you're handy enough to open up a sealed non-remote key fob and are able to bear the mess, you can easily remove the circuit board and examine the fuse with a multimeter to ensure that it is functioning as intended. function. If you're not sure with this, you can visit your local Oreilly or hardware store and utilize their RF frequency tester. This will inform you whether the key fob sends a signal.

Programming

They may lose their connection to the car's receiver because of shock or a low battery, which requires them to be reprogrammed. A professional auto locksmith or main dealer can reprogram your keyfob to get it working again. If resetting or fixing the keyfob is not working it may be necessary to replace it.
