How to Fix a Key Fob That isn't Working
If your key fob isn't working A few easy steps can fix it. The first step is to be sure that it's not the backup remote.
If the backup can lock and unlock your car doors then there's a likely issue with the main remote. The most common causes of key malfunctions for car remotes are battery or circuitry issues.
Battery
The battery inside the key fob could get worn out over the course of time. It is relatively easy to change out batteries, but it is essential to ensure that you select the correct one; you can look in your owner's manual or contact the dealer for the manufacturer to find out the kind of battery you require. It is also a good idea to examine the battery compartment with care because dead batteries can leak harmful chemicals that can cause damage to the remote. If replacing the batteries doesn't solve the issue, it may be that there are other issues that require attention from a professional. For key car repair , if buttons seem to be stuck or damaged It may be necessary to disassemble the remote and rework its parts. You could also try reprogramming the vehicle to recognize the new device.
Buttons
Key fobs can get dirty and worn out from frequent use. This is not unusual however it can cause buttons to cease functioning or require a difficult press to get them to work. This can be very frustrating especially if you're away from home and need to start your vehicle. Even worn-out or malfunctioning buttons can be fixed with a little time and materials you already have at home.
First, verify that the batteries are correctly installed and that the indentation on the back of the button is filled. Then, carefully open the remote and examine the circuit board. Check for signs of corrosion or other signs that buttons are worn out or damaged, such as missing the conductive paint. Then, using a Q-tip dipped in alcohol to gently clean any membrane contacts that have become damaged or have conductive paint missing. Be careful not to rub too hard, because this could damage the conductive painting and prevent the button from firing when pressed.
Check the battery connector's terminals carefully for any loose solder connections. If this is the case, simply connecting them back may restore function to the button. The same process can be used to restore function to any loose connections inside the fob.
If any of the rubber buttons at the front of the keyfob isn't functioning or require to be pressed very hard, the graphite disks at the back of the button might have worn out and need to replaced. You can usually do this by rubbing a pencil over the disks. This should bring the button to life.
If none of this is useful, or if the button still doesn't respond to a hard press It could be because the circuit board is damaged. It is possible to fix this issue by cleaning and re-soldering the fob, but you should have another spare in case it does not work.
Circuitry
The circuit board of your remote control may be dirty, regardless of whether the buttons on the key fob are working or not. The issue can be solved through a thorough examination. The most frequent causes of dirty circuit boards are 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 destroy pins and connectors that are small on the board, which are known as via's.
If you're able to open your key fob, and you don't mind making some mess, we can take the buttons out of their sockets and then solder new ones. It's also worth checking the connections between battery terminals. If they're loose, the buttons may not function properly or become stuck in their down position. Soldering the terminals, and putting the button back into place is typically all that's required to return the key fob that is not working to working condition.

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 drilled into them or run over by a lawnmowers blade or car door handle. The majority of non-remote transponder chips fail, and this could be attributed to an exploded fuse.
If you're not confident opening the key fob, remove the circuitboard and utilize a multimeter to check that the diode is working properly. If you're unsure about doing this, visit your local hardware store or the Oreilly's and they usually have a RF frequency tester that will let you know whether the key fob sending a signal.
Programming
Key fobs are subject to a lot of abuse and aren't completely indestructible. They can lose their pairing to the receiver in your car due to shock or low battery, which requires them to be reprogrammed. A professional auto locksmith, or the main dealer, can reprogram your key fob and get it back up and running again. In the event that resetting and repairing your key fob isn't working it may be time to replace it entirely.
