How to Fix a Key Fob That isn't Working

If your key repair fob isn't functioning There are a few simple steps that can fix it. The first step is to make sure that it's not your backup remote.

If your backup remote cannot unlock and lock the doors of your car key fob repair service, then it is likely that the main remote isn't functioning. The most common causes for car remote key failure are circuitry or battery issues.

Battery

The battery inside a key fob can get worn out over the course of time. It is easy to replace a battery. However it is essential that you choose the right type. You can consult your owner's guide or contact the manufacturer to determine the right type. It's also a good idea to inspect the battery compartment thoroughly since dead batteries may release caustic chemicals that could harm the remote. If replacing the battery does not fix the issue there could be other issues that require attention from a professional. For instance, if the buttons seem to be stuck or damaged It may be necessary to take the remote apart and rework its parts. You could also try reprogramming your vehicle to recognize the new key fob.

Buttons

Key fobs may become dirty and worn-out from frequent use. This is not atypical however, it can cause buttons to cease functioning or require a hard press for them to work. This can be frustrating particularly when you're away from home and you need to start your repair car key fob. Even malfunctioning or worn-out buttons can be fixed with a little effort and materials you already have at home.

First, check that the batteries have been correctly inserted and that the indentation at the back of the button is filled. Then, carefully remove the Remote key repair and inspect the circuit board. Check for signs of rust or other signs the buttons are damaged or worn. For example there could be conductive paint missing. Use a Q-tip dipped into alcohol to gently clean any membrane contact that has become damaged or has conductive paint missing. Be careful not to rub too hard, because this could damage the conductive paint and block the button firing when the button is pressed.

Examine the battery connector's terminals carefully for any loose solder connections. If this is the case, simply soldering them back in place could restore functionality to the button. You can apply the same procedure to restore functionality to any other loose connection inside the fob.

If, for instance, any of the buttons made of rubber on the front of the key fob stop working or require a long press to function it is likely the graphite disks on the back of the button are wearing down and require replacement. You can usually do this by rubbing a pen across the disks. This will bring the button back to life.

If none of this is useful or if the button still does not respond to a firm press, then it may be because the circuit board itself is damaged. It is possible to fix the issue by cleaning and re-soldering your fob but you should also have an extra in case it does not work.

Circuitry

The circuit board inside your remote control could be dirty regardless of whether the buttons on the key fob are working or not. A very thorough inspection will usually resolve this problem. Water and broken cases are the most frequent causes of dirty boards. A damaged case could allow water and other debris into the circuit board, which can cause it to short. Water can also eat away at pins and connectors on the board called via's.

If you're able to open your key fob, and don't mind making a mess, we can remove the buttons from their sockets and solder in new ones. It's also worth checking the battery terminal connections. If they're loose, the buttons could not function or get stuck in their down position. Soldering the terminals and buttons back into place is typically all that's required to return keys that are not in functioning condition.

Non-Remote Transponder Chips

The non-remote chips that are sealed are more durable than their 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 plows over them. The failure of the fuse is usually to blame for non-remote chips failures.

If you're not confident opening the key fob, you may take the circuit board off and use a multimeter to check that the diode is operating correctly. If you're not confident doing this, go to your local hardware store or Oreilly's and they usually have a RFID frequency tester that can let you know if the key fob is transmitting a signal.

Programming

Key fobs endure lots of abuse and aren't impervious to damage. They can break their connection with the receiver inside your vehicle because of shocks or a low battery, requiring changing the program. A professional auto locksmith or a main dealer will be able to reprogram your key fob to get it working again. If resetting or repairing your key fob fails, you may need to replace it.
