How to Fix a Key Fob That isn't Working

If your key fob isn't working A few easy steps can fix it. First, make sure that it's not your backup remote.

If your backup remote can unlock and lock the doors of your car, then it is likely that the primary remote isn't functioning. The majority of car remote key malfunctions are caused by circuitry or battery problems.

Battery

It is not unusual for the battery inside the car key fob to degrade. It is easy to replace a battery. However, it is important that you choose the right kind. You can check your owner's guide or contact the manufacturer to find out the correct type. It's recommended to examine the battery compartment carefully since dead batteries may release caustic chemicals that could harm the remote. If changing the battery doesn't fix the problem there may be additional issues that require professional attention. For instance, if buttons seem stuck or damaged, it may be necessary to take the remote apart and rework its components. You can also try reprogramming your car to recognize the new key fob.

Buttons

Key fobs may become dirty and worn out from repeated use. This is not uncommon however, it can cause buttons to stop functioning or require a long press to work. This can be extremely frustrating, especially if you are away from home and you need to start your car. Even broken or damaged buttons are often fixable with a little effort and the tools you already have at home.

First, ensure that the batteries are up correctly and that the indentation on the back of the button is filled. Then, open the remote with care and inspect the circuit board. Check for signs of corrosion or other signs that the buttons are worn out or damaged, like missing conductive paint. Use a Q-tip that has been dipped in alcohol to gently clean any membrane contact that has become damaged or where conductive paint is missing. Avoid rubbing too hard as this can erode the conductive paint and stop the button firing when the button is pressed.

Also, be sure to check the battery connector terminals for a loose solder connection. Soldering them back to their original position will restore the button's functionality if this is the situation. The same procedure can be used to restore function to any loose connections in the fob.

Finally, if any of the buttons made of rubber 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 at the back of the button are wearing out and need to be replaced. This can usually be done by rubbing a pencil on the disks, which will bring the button back to working.

If none of these solutions work or you not be able to get the button respond when you press it hard, it is possible that the circuitry is failing. It is possible to fix this issue by cleaning and re-soldering the button however, you should have a spare in case it does not work.


Circuitry

If the keys fob buttons are functioning the circuit board in your remote may be dirty. A very thorough inspection is usually enough to fix this problem. The most common causes for dirty circuit boards are water and broken cases. A damaged case could let water and other debris to get into the circuit board, causing it to short. Water can also damage pins and vias, which are the tiny connectors on the board.

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. Also, you should check the connections between the battery terminals. If they are loose, the buttons could not work or even become stuck in their down position. Soldering the terminals and button's back into place is typically all that's required to return the key fob that is not working to working condition.

Non-Remote transponder chips

The sealed non-remote chips are more durable than remote fobs, but they are susceptible to cracking in the event of a hole being drilled in them, or if a car door handle or lawnmowers is pushed over them. The failure of the fuse is usually to blame for non-remote chips failures.

If you are not comfortable opening the key fob, you can remove the circuitboard and use a multimeter to verify that the diode is working properly. If you're not sure with this, go to your local Oreilly or hardware store and test their RF frequency tester. This will inform you whether the key fob is sending signals.

Programming

G28 Car Keys fobs aren't impervious to destruction and can be damaged through a variety of causes. They can lose their pairing with the receiver in your vehicle because of shocks or a low-battery, which requires reprogramming. A professional auto locksmith or a dealer in the main can reprogram the key fob and get it back up and running again. If, in the unlikely event that resetting and fixing your key fob fails, it could be time to replace it entirely.
