How to Fix a Key Fob That isn't Working

Battery
It is not unusual to find a battery on a car key fob to degrade. It is easy to replace batteries. However, it is important that you use the correct type. You can consult your owner's manual or call the manufacturer to find out the correct type.

Buttons
From frequent use, key fobs may become worn and dirty. It is not common for buttons to cease functioning, or require a long press to make them work. This can be very frustrating particularly if you're out of town and need to start your vehicle. Even malfunctioning or worn-out buttons are often fixable with a little time and tools you already have at home.
First, make sure that the batteries are correctly installed and that the indentation on the back of the button has been filled. Open the remote carefully and look over the circuit board. Look for evidence of rust, or other indications that the buttons have been worn or damaged. For example the paint that conducts electricity could be missing. Utilizing a Q-tip that has been dipped in alcohol, gently clean any membrane contacts that are worn or where conductive paint is missing. Don't rub too hard as this can damage the conductive paint, and block the button from firing when you press it.
Also, carefully check the battery connector's terminals for any loose solder connections. Soldering them back in place can restore the button's functionality if this is the case. The same method can be used to restore function to any other loose connections in the fob.
If any of the rubber buttons at the front of the keyfob are not functioning or require to be pressed extremely hard, the graphite disks at the back of the button could have worn out and require replacement. repair car key is usually done by rubbing a pencil over the disks.

It's also worth checking the battery terminal connections. They can become extremely filthy and if they're not tight enough, the buttons might not function or may even remain in their down position. Soldering the terminals and buttons to their proper positions is usually enough to bring a non-working fob to a working condition.
Non-Remote Transponder Chips
The non-remote chips that are sealed are more durable than remote fobs, but they are susceptible to breaking in the event of a hole being drilled in them, or if a car door handle or lawnmowers plows over them. The failure of the fuse is usually to blame for non-remote chip failures.
If you are not comfortable opening the key fob, you can take the circuit board off and use a multimeter to check that the diode is operating correctly. If you're not comfortable with this, visit your local Oreilly or hardware store and test their RF frequency tester. This will tell you whether the key fob is sending signals.
