How to Fix a Key Fob That isn't Working
If your key fob does not work, you can fix it with some simple steps. First, make sure that it's not your backup remote.
If your backup remote is unable to lock and unlock the doors of your car, it is most likely that the primary remote isn't working. The most common causes of car remote key failure are circuitry or battery issues.
Battery
The battery inside the key fob could get worn out over the course of time. It is relatively easy to replace a battery, although it is important to make sure that you use the right type that you can refer to your owner's manual or contact the manufacturer's dealer to find out the kind of battery you need. It is also a good idea to inspect the battery compartment carefully, as dead batteries sometimes release caustic chemicals that could harm the remote. If changing car key repair near me doesn't solve the issue there may be additional issues that require attention from a professional. If the buttons are stuck or broken, for example, it may be necessary disassemble the remote and rework each component. It is also possible to reprogramme the vehicle to recognize the new remote.
Buttons
Key fobs can become filthy and worn out due to repeated use. It is not common for buttons to cease functioning, or require a hard press to make them work. This can be very frustrating, especially if you are away from home and you need to start your car. Even broken or damaged buttons can be fixed with a little effort and the tools you already have at home.
First, verify that the batteries are correctly installed and that the indentation at the back of the button is filled. Then, open the remote with care and examine the circuit board. Check for evidence of rust, or other signs the buttons are worn or damaged. For example there could be conductive paint missing. Then, using the Q-tip, dipped in alcohol, gently clean any membrane contacts that have become worn or have conductive paint missing. Avoid rubbing too hard, as this can erode the conductive paint and stop the button from firing when pressed.
Also, carefully check the battery connector's terminals to ensure a loose solder connection. Soldering them back in place will restore the button's functionality in the event that this is the situation. The same method can be used to restore function to any other loose connections inside the fob.
If any of the rubber buttons at the front of the keyfob isn't functioning or require to be pressing extremely hard the graphite disks on the back of the button may have worn out and will require replacement. It is usually done by rubbing a pencil over the disks. This should bring the button back to life.
If none of these solutions work, or if you still cannot get the button to respond when pressed hard, it could be that the circuitry is failing. It is possible to fix the issue by cleaning and re-soldering the button but you should also have another spare in case it does not work.
Circuitry
The circuit board in the remote control could be dirty regardless of whether the buttons on the key fob function or not. This problem can be resolved through a thorough examination. The most common causes of dirty circuit boards is water and damaged cases. A broken case allows water and other debris to pass through and short circuit the electronic components. Water can also damage pins and small connectors on the board, which are known as via's.
If you're able to open up your key fob and aren't afraid of a little mess, we can de-solder the buttons and solder new ones in their place. Also, you should check the connections between battery terminals. They can become very 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 original positions is often enough to return a malfunctioning fob to working.
Non-Remote transponder chips
The non-remote chips that are sealed are more durable than their remote fobs, but they can be cracked if a hole is drilled into them or if a car door handle or lawnmower runs over them. The majority of non-remote transponder chips fail, and this could be attributed to an exploded fuse.
If you're handy enough to remove a key fob that is sealed and are willing to put up with the mess, you can take off the circuit board and examine the fuse using a multimeter for proper diode function. If you're not comfortable with this, you can go to your local Oreilly or hardware store and use their RF frequency tester. This will tell you whether the key fob is sending signals.
Programming
Key fobs aren't impervious to destruction and are susceptible to damage by a variety of factors. They may lose their connection to the car's receiver because of shock or a low battery, which calls for the reprogramming. A professional auto locksmith or the main dealer, can reprogram your keyfob to get it functioning again. In the rarer case that resetting and fixing your key fob isn't working it may be time to replace it entirely.
