How to Fix a Key Fob That isn't Working
If your key fob isn't functioning, a few easy steps can be taken to fix it. The first step is to make sure that it's not the backup remote.
If your backup remote can lock and unlock the doors of your car, then it is likely that the main remote isn't working. The most frequent causes of key problems with your car remote are circuitry or battery issues.
Battery
The battery inside the key fob may get worn out over the course of time. It is fairly easy to change out batteries, but it is crucial to ensure that you choose the correct type; you can look in the owner's manual or talk to the dealer for the manufacturer to find out the kind of battery you require. It is also a good idea to inspect the battery compartment thoroughly because dead batteries can leak caustic chemicals that can harm the remote. If changing the batteries does not solve the issue, it may be that there are other issues that require attention from a professional. If the buttons are damaged or stuck for instance it could be necessary to take the remote apart and rework each component. You could also try reprogramming your vehicle to recognize the new key fob.
Buttons
Key fobs can get filthy and worn out due to repeated use. This is not unusual, but it can cause buttons to cease functioning or require a hard press for them to function. This can be a hassle especially when you're away from your home and need to switch on your car. Fortunately, even worn out or damaged buttons can be fixed with a little time and a few materials you have in the house.
First, make sure that the batteries are correctly placed and that the indentation on the back of the button has been filled. Then, carefully remove the remote and inspect the circuit board. Examine for signs of rust or other indications that buttons are worn out or damaged, such as missing conductive paint. Utilizing the Q-tip, dipped in alcohol, gently clean any membrane contacts that have become damaged or where conductive paint is missing. Don't rub too hard in order to damage the conductive paint, and block the button from firing when you press it.
Also, be sure to check the battery connector's terminals for a loose solder connection. If this is the case, connecting them back can restore function to the button. The same process can be used to restore function to any other loose connections within the fob.
If, for instance, any of the buttons made of rubber on the front of the key fob stop working or require a difficult press to function it is likely the graphite disks on the back of the button are wearing out and require replacement. This can usually be done by rubbing a pencil over the disks, which will bring the button back to its original state.
If none of these solutions work or you cannot get the button to respond when you press it hard, it could be that the circuitry has failed. It is possible to fix this by cleaning and re-soldering the button, but you should have another spare in case it doesn't work.
Circuitry
Whether or not the key fob buttons are working the circuit board in the remote could be dirty. The issue can be solved through a thorough examination. The most common causes for dirty circuit boards is water and damaged cases. A damaged case can allow water and other debris to get into the circuit board, causing it to short. Water can also eat through pins and vias, which are small connectors that are found on the board.
If you're able to open your key fob and you don't mind making some mess, we can remove the buttons from their sockets and solder in new ones. It's also worth examining the battery terminal connections. If they are loose, the buttons might not function or get stuck in their down position. Soldering the terminals, and putting the button back in their place is generally all that's needed to return a non-working key fob to functioning condition.

The non-remote chips that are sealed are more durable than remote fobs, however they can be cracked if a hole is drilled into them or if a car door handle or lawnmowers plows over them. Fuse failures are usually to blame for non-remote chips failures.
If you're able to open up a key fob that is sealed and are able to bear the mess, you can take off the circuit board and test the fuse with a multimeter for proper diode function. If you're not confident doing this, visit your local hardware store or Oreilly's, and they'll usually have an radio frequency tester that can let you know if the key fob is transmitting a signal.
Programming
Key fobs are subject to lots of abuse and aren't indestructible. They may lose their connection with the receiver in your vehicle due to shocks or low battery, which calls for the reprogramming. A professional auto locksmith or main dealer, can reprogram your keyfob and get it up and running again. In the event that resetting or repairing your key fob doesn't work, it could be time to replace it entirely.
