How to Fix a Key Fob That isn't Working
If your key fob isn't functioning There are a few simple steps that can be taken to fix it. First, check to make sure it's not your backup remote.
If your backup remote cannot lock and unlock the doors of your car, then it is likely that the primary remote isn't functioning. Most problems with car remote keys are caused by battery or circuitry problems.
Battery
It is not uncommon to find a battery on the key fob for cars to degrade. It is fairly easy to change out the battery, however it is important to ensure you use the right type and you can consult your owner's manual, or contact the dealer of the manufacturer to find out the kind of battery you need.

If changing the batteries doesn't solve the problem it could be that there are other issues that require attention by a professional. If buttons are damaged or stuck for instance it might be necessary to take the remote apart and rework each component. It is also possible to reprogramme the vehicle to recognize the new remote.
Buttons
Key fobs can get dirty and worn-out from frequent use. This is not atypical however it can cause buttons to stop working or require a very long press to work. This can be a hassle particularly when you're away from your home and you need to turn on your car.

First, ensure that the batteries are up correctly and that the indentation on the back of the button is filled. Then, carefully open key lock repair near me and examine the circuit board. Check for signs of corrosion or other signs that the buttons are worn out or damaged, such as missing paint that is conductive. Utilizing a Q-tip dipped in alcohol, gently clean any membrane contacts that have damaged or where conductive paint is missing. Avoid rubbing too hard since this could cause damage to the conductive paint and block the button from firing when pressed.
Also, be sure to check the battery connector's terminals to ensure any loose solder connections. Soldering them back to their original position can restore the button's functionality If this is the situation. You can use the same procedure to restore functionality to any other loose connection inside the fob.
If, for instance, any of the buttons made of rubber that are on the front of the key fob have stopped functioning or require a long press to function it is likely the graphite disks at the back of the button are wearing out and require replacement. This can usually be done by rubbing a pencil across the disks, which will bring the button back to working.
If none of these solutions work or you are unable to get the button to respond when pressed hard, it is possible that the circuitry has failed. It is possible to fix the issue by cleaning and re-soldering the button but you should also have a spare in case it doesn't work.
Circuitry
The circuit board inside the remote control could be dirty, regardless of whether the buttons on the key fob are working or not. This issue can be fixed by a thorough inspection. Water and broken cases are the most frequent causes of boards that are dirty. A damaged case allows water and other debris to pass through and short out the electronics. Water can also damage pins and small connectors on the board, referred to as via's.
If you're able to remove your key fob and don't mind making a mess, we can remove the solder from the buttons and solder new ones in their place. Also, it's worth checking the connections between the battery terminals. They can become very filthy and if they're not tight enough, the buttons may not work or even stay in their down position. Soldering the terminals back to their original positions is often enough to bring a non-working fob to a working condition.
Non-Remote Transponder Chips
Sealed non-remote transponder chips are much more durable than remote fobs they are contained in, however they are still susceptible to being broken by a hole being that is drilled into them or over by a lawnmowers blade or door handle for a car. Most of the time non-remote transponder chip failures could be attributed to an exploded fuse.
If you're handy enough to open a sealed non-remote key fob and can tolerate the mess, you can take off the circuit board and examine the fuse using a multimeter to ensure that it is functioning as intended. function. If you're not confident doing this, go to your local hardware store or Oreilly's and they usually have a RF frequency tester that will let you know whether the key fob sending signals.
Programming
Key fobs endure a lot of abuse and aren't completely indestructible. They can lose their pairing with the receiver inside your vehicle due to shocks or a low-battery, which requires the reprogramming. A professional auto locksmith or main dealer will be able to reprogram your key fob and get it working again. If resetting or replacing your key fob fails it may be necessary to replace it.
