Key Fob is not Working

Reasons Why the Key Fob is not Working

A key fob is a very convenient feature that modern cars have. However, the key fob can malfunction and stop working. This article will reveal all possible reasons why the key fob is not working. The key fob can stop working when you are in a hurry and can be a huge inconvenience. Some cars will not unlock without the key fob. On the other hand, you can try to fix it yourself by figuring out the problem. The possible reasons if a key fob is not working are mentioned below.

Reasons Why the Key Fob is not Working?

There are different reasons why the car remote might stop working. There could be a problem with the remote or a problem with the car. You will have to find out the problem before you try to fix it. 

Dead Batteries

The most common problem is dead batteries. A battery powers the key fob, and these batteries have a long life but will eventually run out. The battery comes in contact with the transmitter to send signals. The transmitter sends the signal, and the receiver acts on it. If the batteries are dead, the key fob will not be able to send signals. However, there is a way that you can verify that the problem is with the batteries. You can open up the remote to check if everything is in order. If you find no problems, then the batteries are the culprit. Replace the batteries, and the key fob should work just fine. 

The key fob is not Paired

The key fob works like a Bluetooth device. The remote has a transmitter that sends the signal to the receiver. You have to pair the remote with the receiver to send signals. If you do not pair it, the receiver will not receive any signals and thus will not work. Furthermore, some key fobs have to be programmed to control other features in the car. This problem usually occurs with second-hand car owners. It can also occur after you replace the batteries in the key fob. The key fob can reset itself after replacing the batteries, and you will have to reprogram it to get it working again. 

How to program and pair the key fob?

There are many different ways to program and pair the key fob with the receiver. It depends on the manufacturer and the model of the car. You can try some methods to pair it with the receiver.

  • Enter the car and insert the key in the ignition.
  • Turn the key to the run position and back a few times.
  • Do not start the car; you should move the key only till the run position. 
  • Check to see if the key fob works.

Another primary method to pair the key fob is:

  • Enter the car and lock the doors manually.
  • Insert the key in the ignition and take it out instantly.
  • Repeat this process at least six times.
  • Now insert the key in the ignition and start the car.
  • Press any button on the remote to check if it works.

The most effective method is to read the owner’s manual to find out how to reprogram and pair the remote.

Some other methods require special skills or tools. Lock repair and replacement in Schiller Park can help you out if you can’t solve this issue. 

Damaged Transmitter and Receiver

As mentioned above, the key fob operates by sending signals through a transmitter to a receiver. If the transmitter is damaged, the key fob will not be able to interact with the receiver. It is difficult to fix this issue on your own. You will have to contact an automotive locksmith in Schiller Park to fix this issue. A loose wire or wear and tear can cause this problem. Similarly, if the receiver is damaged, the key fob will not work. 

Broken Key Fob

A broken key fob is also another common reason if a key fob is not working. Key fobs are not indestructible. You can damage the internal components of the remote if you do not take care of it. You can open the remote to check if all the components are intact and all the wires are connected. 

Protection from Thieves

Most modern cars have a security system that prevents thieves from breaking into the car. Modern cars detect the proximity of the key fob. If your key is inside your pocket and you are nowhere near the car, and somebody tries to break in, the car will shut down completely. You will not be able to open it with your remote. This feature is mostly in keyless cars.  

Car Battery is Low

As mentioned above, if the key fob’s battery is low or dead, it will not be able to communicate with the car. Similarly, if the car battery is also low or dead, it will not receive the signals sent by the transmitter. You can use jumper cables to recharge your battery. If there is a problem with the battery, you may have to replace it.
