How to Fix a Key Fob That isn't Working If your key fob isn't working There are a few simple steps that can be taken to fix it. The first step is to be sure it's not the backup remote.

Battery The battery in the key fob could wear out over time. It is quite simple to change out a battery, although it is essential to ensure you use the right type and you can consult the owner's manual or talk to the manufacturer's dealer to determine the type of battery you require. It's also a good idea to examine the battery compartment carefully, as dead batteries sometimes leak caustic chemicals that can cause damage to the remote. If changing car key fob repair does not solve the issue it could be that there are other issues that require professional attention. If the buttons are broken or stuck, for example, it may be necessary take the remote apart and rework each component. It is also possible to reprogramme the vehicle to recognize the new device. Buttons Key fobs can get dirty and worn-out from frequent use. This is not uncommon however it can cause buttons to cease working or require a very difficult press to get them to work. car key fob repair can be a hassle, especially when you are away from your home and have to turn on your car. Even broken or damaged buttons can be fixed with a little time and tools you already have at home. First, make sure that the batteries are properly installed and that the indentation on the back of the button has been filled. Then, carefully open the remote and examine the circuit board. Examine for signs of rust or other signs that the buttons are worn out or damaged, such as missing the conductive paint. Use a Q-tip dipped into alcohol to gently clean any membrane contact that has become worn-out or where conductive painting is missing. Avoid rubbing too hard, because this could damage the conductive painting and prevent the button firing when pressed. Also, make sure to inspect the battery connector's terminals to ensure any loose solder connections. Soldering them back to their original position will allow the button to function again if this is the case. The same process can be used to restore function to any loose connections within the fob. In the end, if any of the buttons made of rubber on the front of the key fob stop working or require a very long press to function, it is likely that the graphite disks on the back of the button are deteriorating and need to be replaced. It is usually done 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 are unable to get the button to respond when you press it hard, it could be that the circuitry is failing.

If you're able to remove your key fob and aren't afraid of making a mess, we can remove the solder from the buttons and solder new ones in their place. Also, you should check the connections between the battery terminals. If they're loose, the buttons could not function properly or become stuck in their down position. Soldering the terminals, and putting the button back in place is usually all it takes to restore keys that are not in working order. Non-Remote Transponder Chips The non-remote chips that are sealed 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 lawnmower runs over them. The failure of the fuse is usually to blame for non-remote chips failures. If you're not comfortable opening the key fob, remove the circuitboard and use a multimeter to verify that the diode is functioning correctly. If you're not confident doing this, head to your local hardware store or Oreilly's, and they'll usually have an RFID frequency tester that can determine whether the key fob sending signals. Programming Key fobs endure lots of abuse and aren't impervious to damage. They can lose their pairing to the car's receiver due to shock or low battery, requiring the reprogramming.
