How to Fix a Key Fob That isn't Working

If your key fob isn't functioning There are a few simple steps that can fix it. The first step is to make sure that it's not the backup remote.

If the backup is able to lock and unlock your car door, then there's a likely issue with the main remote. Most car remote key failures result from battery or circuitry problems.

Battery

The battery inside the key fob could wear out over time. It is simple to replace a battery. However it is essential that you use the correct type. You can consult the owner's manual or contact the manufacturer to determine the correct type. It is recommended to inspect the battery compartment with care, as dead batteries sometimes release caustic chemicals that could damage the remote. If changing the battery doesn't solve the issue there may be additional issues that require professional attention. For instance, if buttons seem to be stuck or damaged, it may be necessary to take the remote apart and rebuild its components. You could also try reprogramming the vehicle to recognize the new key fob.


Buttons

Key fobs may become dirty and worn-out from repeated use. It is not unusual to have buttons stop working, or to require a long press to get them working. key car repair can be very frustrating especially when you're away from home and you need to switch on your car. Fortunately, even worn out or broken buttons can usually be fixed with a bit of time and a few materials you may already have around the home.

First, make sure that the batteries are correctly installed and that the indentation on the back of the button is filled. Then, carefully remove the remote and inspect the circuit board. Check for signs of rust or other signs the buttons are damaged or worn out. For example, conductive paint may be missing. Then, using a Q-tip dipped in alcohol to gently clean any membrane contacts that have worn or where conductive paint is missing. Do not rub too vigorously as this can damage the conductive paint and stop the button from firing when you press it.

Check the battery connector's terminals carefully for any loose solder connections. Soldering them back to their original position will restore the button's functionality in the event that this is the case. The same method can be used to restore function to any other loose connections inside the fob.

If any of the rubber buttons located at the front of the keyfob aren't functioning or require to be pressing extremely hard the graphite disks on the back of the button might have worn out and will need to replaced. You can do this by rubbing a pencil over the disks. This will bring the button back to life.

If none of these solutions work, or if you still cannot get the button to respond when you press it hard, it could be that the circuitry has failed. This can sometimes be repaired with a quick clean and refitting, but it's recommended to have an additional fob available in the event this method does not work for you.

Circuitry

Whether or not the key fob buttons function, the circuit board inside your remote might be dirty. This issue can be fixed by a thorough inspection. Broken cases and water are the most frequent causes of boards that are dirty. A damaged case can allow water and other debris to enter the circuit board, causing it to short. Water can also damage pins and vias, which are the tiny connectors on the board.

If you're able to open your key fob and aren't afraid of some mess, we can de-solder the buttons and solder new ones in their place. It's also worth checking the battery terminal connections. They can become extremely dirty and if they're loose, the buttons might not function or even stick in their down position. Soldering the terminals and buttons back in their place is generally all it takes to restore the key fob that is not working to working condition.

Non-Remote transponder chips

The non-remote chips sealed in a sealed case are more durable than remote fobs. However, they are susceptible to breaking when a hole is made in them or when a door handle for a car or lawnmowers is pushed over them. Failures of the fuse are typically to blame for non-remote chip failures.

If you are not comfortable opening the key fob, take the circuit board off and use a multimeter to determine if the diode is functioning properly. If you're not sure with this, you can go to your local Oreilly or hardware store and utilize their RF frequency tester. This will tell you whether the key fob sends signals.

Programming

Key fobs are not indestructible and are susceptible to being damaged by a variety of factors. They can lose their pairing to the receiver in your car due to shock or low battery, which requires them to be reprogrammed. A professional auto locksmith or dealer can reprogram your key fob to get it functioning again. If resetting or replacing the keyfob is not working it is possible to replace it.
