How to Fix a Key Fob That isn't Working If your key fob doesn't work, a few easy steps can fix it. The first step is to be sure it's not the backup remote. If your backup remote can unlock and lock the doors of your vehicle, it is most likely that the primary remote is not working. Most problems with car remote keys are caused by circuitry or battery issues. Battery It is not unusual to find a battery on the key fob for cars to degrade. It is fairly easy to change out a battery, although it is essential to make sure that you choose the correct type; you can look in your owner's manual or contact the dealer of the manufacturer to find out what kind of battery you need. It is recommended to inspect the battery compartment with care because dead batteries can release caustic chemicals that could harm the remote. If replacing the batteries doesn't solve the issue it could be because there are other issues that require attention from a professional. If the buttons are stuck or broken for instance, it may be necessary disassemble the remote and rework each component. It is also possible to reprogramme the vehicle to recognize the new fob. Buttons Key fobs may become dirty and worn-out from frequent use. car key repair near me is not atypical however it can cause buttons to cease working or require a very difficult press to get them to work. This can be a huge hassle particularly if you're out of town and need to start your car. Fortunately, even worn-out or malfunctioning buttons can often be fixed with a bit of time and some of the materials you might already have in the home. First, make sure that the batteries have been correctly installed and that the indentation at the back of the button is filled. Take the remote apart and look over the circuit board. Examine for signs of rust or other signs that buttons are worn out or damaged, like missing the conductive paint. Then, using a Q-tip dipped in alcohol, gently clean any membrane contacts that have worn or where conductive paint is missing. Be careful not to rub too hard, because this could damage the conductive paint and block the button from firing when it is pressed. Also, carefully check the battery connector's terminals to ensure an unattached solder connection. If this is the case, simply soldering them back in place can bring back function to the button. The same procedure can be used to restore function to any loose connections within the fob. If any of the rubber buttons on the front of the keyfob are not working or need to be pressed very hard the graphite disks on the back of the button could have worn out and need to replaced. 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 you cannot get the button to respond when you press it hard, it is possible that the circuitry has failed. It is possible to fix this by cleaning and re-soldering your fob but you should also have a spare in case it does not work. Circuitry Whether or not the keys fob buttons are functioning, the circuit board inside your remote might be dirty. A thorough inspection is often enough to resolve this problem. The most frequent causes of dirty circuit boards is water and damaged cases. A damaged case can allow water and other debris to get in and short out the electronics. Water can also damage pins and vias, which are the tiny connectors found on the board. If you are handy enough to open your key fob, and aren't afraid of making some mess, we can remove the buttons from their sockets and put in new ones. It's also worth examining the battery terminal connections. 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 back to their original positions is often enough to restore a non-working fob back to working. Non-Remote transponder chips Sealed non-remote transponder chips are much more durable than the remote fobs that have them but they can be cracked by a hole that is drilled into them or over by a lawnmowers or door handle for a car. The failure of the fuse is usually to blame for non-remote chips failures. If you're not comfortable opening the key fob, you may remove the circuitboard and utilize a multimeter to check that the diode is working properly. If you're unsure about doing this, go to your local hardware store or Oreilly's and they will usually have an RF frequency tester that will let you know if the key fob is sending signals. Programming Key fobs endure lots 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, requiring changing the program. A professional auto locksmith or a dealer in the main, can reprogram your keyfob and get it working again. If resetting or fixing your keyfob does not work it may be necessary to replace it.
