Battery

It is not unusual for the battery in the car key fob to degrade. It is quite simple to change out a battery, although it is important to ensure that you use the right type and you can consult your owner's manual or contact the dealer of the manufacturer to find out what kind of battery you require. It is also crucial to check the battery compartment, as batteries that are not working properly can release toxic chemicals that could damage the remote. If replacing the battery does not solve the issue there could be other issues that require professional attention. If the buttons are broken or stuck, for example it might be necessary to disassemble the remote and rework each component. You could also try reprogramming the vehicle to recognize the new fob.

Buttons

Through frequent use, key fobs may wear out and become dirty. It is not common to have buttons stop working, or to require a long push to make them work. This can be frustrating, especially when you are away from your home and you need to start your car. Even broken or damaged buttons are often fixable with a bit of time and the tools you already have at home.

First, make sure the batteries are properly charged 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 corrosion or other signs that the buttons are worn or damaged, such as missing paint that is conductive. Use a Q-tip dipped in alcohol, gently clean any membrane contacts that are worn or have conductive paint missing. Be careful not to rub too hard, because this could damage the conductive paint and stop the button firing when the button is pressed.

Also, carefully check the battery connector's terminals to ensure any loose solder connections. Soldering them back to their original position will restore the button's functionality in the event that this is the situation. You can apply the same process to restore functionality to any other loose connection within the fob.

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

It's also worth examining the battery terminal connections. If they are loose, the buttons may not function or get stuck in their down position. Soldering terminals and buttons back into place is usually enough to bring a non-working fob to working.

Non-Remote Transponder Chips

The non-remote chips that are sealed are more durable than their remote fobs. However, 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 plows over them. Failures of the fuse are typically to blame for non-remote chips failures.
