How to Fix a Key Fob That isn't Working

If your key fob doesn't work and you're not sure why, you can fix it with some simple steps. First, make sure that it's not the backup remote.

If your backup remote is unable to lock and unlock the doors of your vehicle, it is likely that the main remote isn't working. The majority of car remote key malfunctions are caused by circuitry or battery problems.

Battery

The battery in the key fob could get worn out over the course of time. It is easy to replace batteries. However it is essential to select the right kind. You can refer to the owner's manual or contact the manufacturer to inquire about the right kind. It is also important to check the battery compartment as batteries that are not working properly can release caustic chemicals which can damage the remote. If changing the batteries does not solve the issue it could be because there are other issues that require attention by a professional. If the buttons are damaged or stuck, for example, it may be necessary take the remote key repair near me apart and vehicle rework each component. You can also try reprogramming the vehicle to recognize the new device.

Buttons

Key fobs may become dirty and worn out from frequent use. This is not atypical, but it can cause buttons to cease functioning or require a long press to work. This can be a huge hassle especially if you're away from home and need to start your vehicle. Even broken or damaged buttons can be fixed with a little time and the tools you already have at home.

First, verify that the batteries have been correctly placed and that the indentation at the back of the button is filled. Then, vehicle carefully open the remote key repair and examine the circuit board. Look for signs of corrosion or other signs that the buttons are worn out or damaged, such as missing conductive paint. Use a Q-tip dipped in alcohol, gently clean any membrane contacts that have damaged or have conductive paint missing. Be careful not to rub too hard, since this could cause damage to the conductive paint and block the button from firing when it is it is pressed.

Also, make sure to inspect the battery connector terminals for any loose solder connections. If this is the case, soldering them back in place may restore functionality to the button. You can follow the same method to restore functionality to any other loose connection inside the fob.

Finally, if any of the buttons made of rubber that are on the front of the key fob stop working or require a very long press to function it is likely the graphite disks at the back of the button are wearing out and need to be replaced. You can do this by rubbing a pen over the disks. This should bring the button back to life.

If none of these solutions work, or if you still cannot get the button to respond when pressed hard, it could be that the circuitry is failing. This can be fixed by a quick clean and re-soldering, but it is recommended to have an additional fob in case this method fails for you.

Circuitry

The circuit board of your remote control may be dirty, regardless of whether the buttons on the key fob function or not. A thorough examination is usually enough to fix this issue. Water and broken cases are the most common causes of boards that are dirty. A broken case allows water and other debris to enter and short circuit the electronics. Water can also damage pins and vias, which are the tiny connectors that are found on the board.

If you're able to remove your key fob, and you're not afraid of some mess, we can take off the buttons and solder new ones in their place. It's also worth looking at the battery terminal connections. If they're loose, the buttons may not function or get stuck in their down position. Soldering the terminals and buttons into place is usually enough to bring a non-working fob to working.

Non-Remote Transponder Chips

Sealed non-remote transponder chips are more durable than the remote fobs they are contained in, but they can be cracked by a hole that is drilled into them or over by a lawnmowers blade or car door handle. The majority of non-remote transponder chip failures can be attributed to a blown fuse.

If you're handy enough to open up a sealed non-remote key fob and can tolerate the mess, you can remove the circuit board and check the fuse using an instrument to verify diode function. If you're not confident doing this, go to your local hardware store or the Oreilly's and they usually have an RF frequency tester that will determine if the key fob is transmitting a signal.

Programming

Key fobs endure a lot of abuse and aren't indestructible. They can break their connection with the receiver inside your vehicle due to shocks or low battery, which calls for changing the program. A professional auto locksmith or dealer can reprogram your key fob and get it back up and running. In the event that resetting or repairing your key fob doesn't work, it could be time to replace it entirely.
