How to Fix a Key Fob That isn't Working
If your key fob doesn't work A few easy steps can fix it. The first step is to be sure that it's not the backup remote.
If your backup remote is unable to unlock and lock the doors of your vehicle, it is likely that the primary remote is not working. The most common causes of key problems with your car remote are battery or circuitry issues.
Battery
It is not unusual to find a battery on the car key fob to wear out. It is easy to replace batteries. However it is essential to select the right type. You can consult the owner's manual or contact the manufacturer to find out the right kind. It is also important to check the battery compartment as batteries that are not working properly can release caustic chemicals which can damage the remote. If changing the battery doesn't solve the issue, there may be other issues that require attention from a professional. If buttons are stuck or broken, for example it could be necessary to disassemble the remote and rework each component. You can also try reprogramming the vehicle to recognize the new remote.
Buttons
From frequent use, key fobs could become worn and dirty. It is not common to have buttons stop functioning, or require a hefty press to get them working. This can be frustrating, especially when you are away from your home and need to switch on your car. Even malfunctioning or worn-out buttons are often fixable with a little effort and materials you already have at home.
First, verify that the batteries have been correctly installed and that the indentation at the back of the button has been filled. Then, open the remote with care and look over the circuit board. Check for signs of corrosion or other indications that the buttons are worn or damaged, like missing paint that is conductive. Then, using a Q-tip that has been dipped in alcohol to gently clean any membrane contacts that have become damaged or where conductive paint is missing. Avoid rubbing too hard because this could damage the conductive paint and stop the button firing when pressed.
Also, be sure to check the battery connector's terminals to ensure any loose solder connections. If this is the case, soldering them back in place can bring back function to the button. The same process can be used to restore function to any loose connections within the fob.
If, for instance, any of the buttons made of rubber that are on the front of the key fob have stopped working or require a long press to function, it is likely that the graphite disks on the back of the button are wearing out and need to be replaced. You can usually do this by rubbing a pen over the disks. This should bring the button back to life.
If none of these solutions work, or if you still not be able to get the button respond when pressed hard, it could be that the circuitry has failed. This can be fixed with a quick clean and replacing the solder, but it is recommended to have an additional fob on hand in the event that this method doesn't work for you.
Circuitry
The circuit board of your remote control may be dirty regardless of whether the buttons on the key fob are working or not. A thorough inspection is usually enough to fix this issue. The most frequent causes of dirty circuit boards is water and damaged cases. A damaged case could allow water and other debris to enter the circuit board, which can cause it to short out. Water can also eat through pins and vias, which are tiny connectors found on the board.
If you are handy enough to open your key fob, and don't mind making a mess, we can take the buttons out of their sockets and put in new ones. It's also worth examining the battery terminal connections. They can become very dirty and if they're loose, the buttons may not work or even stick in their down position. Soldering the terminals and buttons into place is usually enough to return a malfunctioning fob back to working.

Sealed non-remote transponder chips are much more durable than the remote fobs that contain them but they can still be damaged by a hole that is made in them or pushed over by a lawnmowers or car door handle. The failure of the fuse is usually to blame for non-remote chips failures.
If you are not comfortable opening the key fob, you may remove the circuitboard and utilize a multimeter to check that the diode is working correctly. If you're not comfortable doing this, go to your local hardware store or Oreilly's, and they will usually have an RFID frequency tester that can let you know whether the key fob is sending a signal.
