Remote Key Fob Repairs You Can Do at Home

If your remote key fob stop working, you may be tempted to visit an establishment to get it reprogrammed. Instead, you can try some simple fixes at home.


Start with a replacement battery. Flat watch-style batteries are cheap and easy to find at hardware stores. Then take a close look at the key fob and look for buttons that are worn out or out of place.

Dead Battery

The key fob is a tiny electronic device that makes it easy to lock or unlock your vehicle. It works by using a radio transmitter which transmits codes to a receiver inside your car. Key fob batteries usually last for a long period of time, but they may die at any time. Check the LED light, or try pressing one of the buttons to determine whether it's dead. If the key fob will not respond to press, then the battery is dead and needs to replaced.

The process of replacing the battery in the key fob is simple and quick. It's usually as easy as opening the key fob, then removing the old battery and replacing it with a new one. Fobs have small batteries, like those found in hearing aids and watches which are sold at general stores and home improvement centers. They are usually shaped as small coins with plus and minus symbol on the bottom. If you're not sure of the type of battery your fob takes, consult the owner's manual, or look on the key fob itself for an identification label.

After changing the battery the fob's key should perform as expected. If it doesn't, there may be another issue with your vehicle or its system that's making the fob fail to function properly. If this is the situation you'll need roadside assistance.

You could be able to purchase replacement keys from a dealer or online, based on the model and make of your car. It is often cheaper and more convenient to purchase an entirely new key fob rather than to repair a broken one.

Buttons Aren't Responding

If you have been driving around for a while and notice that the keys' buttons aren't working it could be due to an issue with worn out button sensors. The buttons made of rubber on a majority of fobs can wear out with time. This can cause them to function properly when pushed in a certain way or under extreme pressure. This is a problem that occurs for a lot of fobs and can be easily solved with a few simple DIY steps.

The fob transmits an unlocking signal to the receiver inside the car. If the receiver is damaged, it could stop receiving the signal, and stop the key from functioning to open or start the vehicle. This can be resolved by having a mechanic examine the receiver to look for damage. In most instances, this will be free or for a small cost depending on the make of the car you own.

It's not surprising that key fobs are often used and are often tossed into pockets and purses. They can become finicky and only function when they are pressed in a particular manner. It is not difficult to fix most fobs, as the buttons are easily strengthened with silicone and a little bit of effort.

Press and hold the lock and unlock buttons on your keyfob until hear the vehicle sound. You'll need to repeat this a few times in succession in order to get the button to activate. Next, you will need to switch your key into and out of the car's ignition several times more in order to reset the connection between the fob and your car. Once key car repair has been restored, you are able to remove the key from the ignition and then unlock your car using the remote. Repeat the process as needed to get your fob working again. If you're unable to fix the fob following this process it might need to be replaced completely. If you decide to replace the fob, be sure it's programmed to match your vehicle's model and make.

Keychain Loop Breaks

If the plastic loop of the key fob breaks it will not function to lock or unlock your vehicle. The replacement of the keychain loop is an easy solution.

Key fobs can also malfunction because of water or moisture damage. The signs include a decreased range of operation, or no functionality at all. Drying the key fob and replacing the battery may fix the issue, but sometimes professional repair or replacement is required.

Key fob buttons might get worn out over time, leading to less functionality or a lack of responsiveness. This might require an entirely new key fob case or button replacement, but most of the time, the issue can be solved by changing the programming. Signal interference from electronic devices nearby could interfere with the connection between your key fob and your vehicle, causing problems with unlocking or locking. This might require a diagnostic test performed by the dealership in order to troubleshoot and resolve. This is usually the case with older electric keys that rely on infrared signals to operate and require an optical line of sight. Most modern microchipped keys communicate with your car using the challenge-response method of authorization via radio frequency.

Pairings that are lost or damaged

Over time, keyfob batteries lose power. If the battery has lost much of its charge, the remote may no longer respond to commands. Replacing the battery will usually fix this problem, but you may also have to have the remote reprogrammed.

Modern cars have key fobs that allow for many functions. They can raise or lower windows, trigger alarms, turn on the interior lights, and even start certain vehicles. It is possible for owners to use the wrong buttons due to accident. It is a good idea to keep your owner's manual nearby when you are using your key fob, so that you can refer to the specific sections that deal with the different features of your vehicle.

A fob could not function due to the remote's signal being damaged or lost. Certain of the latest key fobs utilize sophisticated encryption techniques to stop thieves from stealing the signals and generating remotes or key fobs that are not authorized that can unlock your car. You will probably need to visit an auto locksmith or dealer in order to re-program the fob and restore its function.

Some automakers provide their own instructions available for reprogramming key fobs yourself. Often, these procedures are easy enough to be performed at home. However, this is usually not a good option for people who have no prior electronic experience. It is recommended to leave this sort of work to professionals.

Key fobs are subject to more wear and tear if they're used and handled regularly. The buttons on a key fob can get jostled around, and the case could break or crack. Keep a spare fob on you at all time. This will save you time if your remote breaks down when you're out and about. Keep it close to your bed at all times, so you can press the panic button in the event that you hear noises during the night.
