How to Fix a Key Fob That isn't Working

If your key fob does not 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 is able to lock and unlock your car door, it is most likely an issue with the primary remote. The most frequent causes of car remote key failure are circuitry or battery issues.

Battery

It is not unusual for the battery inside a car key fob to degrade. It is relatively easy to change out batteries, but it is crucial to make sure that you use the right type that you can refer to your owner's manual, or contact the dealer for the manufacturer to find out what kind of battery you need. It's also a good idea to examine the battery compartment thoroughly because dead batteries can leak harmful chemicals that can damage the remote. If changing the batteries doesn't solve the problem, it may be that there are other issues that require professional attention. If buttons are damaged or stuck for instance it could be necessary to remove the remote and rebuild each component. You can also try reprogramming the vehicle to recognize the new remote.

Buttons

Key fobs may become filthy and worn out due to frequent use. This is not uncommon, but it can cause buttons to cease functioning or require a long press to work. This can be very frustrating, especially when you are away from your home and you need to start your car. Fortunately, even worn-out or broken buttons can usually be fixed with just a bit of time and a few materials you may already have around the home.

First, verify that the batteries have been correctly installed and that the indentation on the back of the button is filled. Take the remote apart and inspect the circuit board. Examine for signs of rust or other signs that the buttons are worn or damaged, such as missing the conductive paint. Use a Q-tip that has been dipped in alcohol, gently clean any membrane contacts that have 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 terminals carefully for any loose solder connections. Soldering them back in place can restore the button's functionality If this is the case. You can apply the same procedure to restore functionality to any other loose connection within the fob.

Finally, if any of the buttons made of rubber that are on the front of the key fob aren't functioning or require a difficult press to function it is likely the graphite disks on the back of the button are wearing out and require replacement. You can usually do this by rubbing a pen over the disks.  key repair  should bring the button to life.

If none of these solutions work, or if you still not be able to get the button respond when you press it hard, it is possible that the circuitry has failed. It is possible to fix the issue by cleaning and re-soldering the button, but you should have another spare in case it doesn't work.

Circuitry

If the keys fob buttons are functioning, the circuit board inside the remote could be dirty. A thorough examination is usually enough to fix this problem. Broken cases and water are the most frequent causes of boards that are dirty. A damaged case could allow water and other debris to enter the circuit board, causing it to short out. Water can also destroy pins and connectors on the board called via's.

If you're skilled enough to open your key fob, and you don't mind making some mess, we can remove the buttons from their sockets and solder in new ones. It's also worth examining the battery terminal connections. They can become very dirty and if they're loose, the buttons might not function or may even remain in their down position. Soldering the terminals and buttons back in place is usually all that's needed to return a non-working key fob to functioning condition.

Non-Remote Transponder Chips

Sealed non-remote transponder chips are much more durable than remote fobs that have them but they can still be cracked by a hole made in them or pushed over by a lawnmowers or car door handle. Fuse failures are usually to blame for non-remote chip failures.

If you're able to remove a sealed non-remote key fob and can tolerate the mess, you can take off the circuit board and examine the fuse using a multimeter to ensure that it is functioning as intended. function. If you're not comfortable with this, you can visit your local Oreilly or hardware store and test their RF frequency tester. This will inform you whether the key fob is sending signals.

Programming

Key fobs aren't impervious to destruction and are susceptible to being damaged by a variety of factors. They may lose their connection with the receiver in your vehicle because of shocks or a low battery, requiring reprogramming. A professional auto locksmith, or a dealer in the main can reprogram your keyfob to get it up and running again. If resetting or fixing the keyfob is not working it may be necessary to replace it.
