How to Fix a Key Fob That isn't Working If your key fob doesn't work There are a few simple steps that can fix it. The first step is to make sure it's not the backup remote. If the backup remote is able to lock and unlock your car door, then there is likely an issue with the main remote. Most problems with car remote keys are caused by circuitry or battery problems. Battery It is not unusual to find a battery on the key fob for cars to degrade. It is relatively easy to replace the battery, however it is important to make sure that you use the right type and you can consult the owner's manual or talk to the dealer of the manufacturer to find out what kind of battery you need. It is also crucial to inspect the battery compartment, since batteries that are not working properly can release toxic chemicals that could damage the remote. If changing the batteries does not solve the issue it could be that there are other issues that require professional attention. For instance, if the buttons appear stuck or damaged, it may be necessary to take the remote apart and rebuild its components. car key repair shop is also possible to reprogramme the vehicle to recognize the new remote. Buttons Key fobs may become filthy and worn out due to repeated use. It is not unusual for buttons to stop functioning, or require a long press to get them working. This can be a huge hassle, especially if you are away from home and you need to start your vehicle. Even broken or damaged buttons are often fixable with a little effort and materials you already have at home. First, make sure that the batteries are properly placed and that the indentation at the back of the button is filled. Open the remote carefully and inspect the circuit board. Check for signs of corrosion or other signs that the buttons are worn out or damaged, like missing paint that is conductive. Use a Q-tip dipped into rubbing alcohol to gently clean any membrane contact that has become damaged or where conductive paint is missing. Be careful not to rub too hard, since this could cause damage to the conductive paint and block the button firing when it is pressed. Check the battery connector's terminals carefully for any loose solder connections. If this is the case, connecting them back can bring back function to the button. The same procedure can be used to restore function to any other loose connections within the fob. Finally, if any of the buttons made of rubber that are on the front of the key fob aren't working or require a very difficult press to function it is likely that the graphite disks that are on the back of the button are wearing down and require replacement. It is usually done by rubbing a pencil over the disks. This will bring the button back to life. If none of this is helpful or if the button still doesn't respond to a hard press It could be the case that the circuit board itself has become damaged. It is possible to fix this by a quick clean, and replacing the solder, but it is recommended to have an additional fob on hand in the event that this method does not work for you. Circuitry Whether or not the keys fob buttons are functioning the circuit board that is inside your remote may be dirty. The issue can be solved by a thorough inspection. The most frequent causes of dirty circuit boards are water and damaged cases. A damaged case allows water and other debris to pass through and short out the electronic components. Water can also destroy pins and small connectors 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 remove the buttons from their sockets and put in new ones. Also, you should check the connections between battery terminals. They can become extremely dirty and if they're loose, the buttons may not work or may even remain in their down position. Soldering terminals and buttons back to their proper positions is usually enough to bring a non-working fob to working. Non-Remote transponder chips The sealed non-remote chips are more durable than remote fobs, however they are susceptible to cracking when a hole is made into them or in the event that a door handle of a car or lawnmowers is pushed over them. Most of the time, non-remote transponder chip malfunctions could be attributed to blowing fuses. If you're not confident opening the key fob, you can take the circuit board off and use a multimeter to determine if the diode is operating correctly. If you don't feel comfortable with this, visit your local Oreilly or hardware store and use their RF frequency tester. This will inform you whether the key fob sends an RF signal. Programming Key fobs are subject to a lot of abuse and aren't indestructible. They may lose their connection to the car's receiver due to shock 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. If, in the unlikely event that resetting and fixing your key fob fails it could be the time to replace it entirely.
