Even while the Ford key fob is a time saver, problems with it can be a cause of irritation. When the battery in your Ford key fob is dead, there are a few things you may do to get it operating again.

Many Ford owners deal with this issue on a regular basis. There are a number of reasons why this is happening and how to remedy it in this post.

After a battery change, your Ford key fob may not operate. This is most likely due to the battery change itself. After changing the battery in the key fob remote, the key must be reset to the automobile since the key was erased. That’s why your key fob remote isn’t doing anything.

Replacing the battery in your key fob remote will necessitate reprogramming it to the car.

What Is A Key Fob?

It is possible to lock and unlock your vehicle’s doors remotely with a key fob. On your automobile, you can also use it to set off the car’s panic alert. When you have a key fob, you’ll find buttons for locking and unlocking the doors and one for activating a panic alarm.

How A Key Fob Works

Sending radio signals to a receiver inside the car is how a key fob works. Locks or an alarm can then be activated by the receiver.

When you press a button on a key fob remote, the receiver receives a new code each time you do so. Intercepting the signal and unlocking your vehicle without your consent is therefore challenging.

One of the most typical causes of your Ford key fob not working after a battery change is that it has to be reset, as we’ve already discussed.

One of the following may be the cause of your key fob remote not working after you’ve replaced the battery:

The key fob remote was not properly programmed for the vehicle

In order for the key fob to work, it must be properly programmed to the car. Changing the battery in your key fob remote may not solve the problem if the remote is still not working after the battery has been replaced.

The receiver is not working

Key fob remote signals are received by the receiver, which then turns on the locks or alarm. The key fob will not function if it cannot communicate with the receiver due to a faulty receiver.

The battery in the key fob remote is low

The battery in your key fob remote may be running low even if you just replaced it. The batteries in key fobs last only a short time and consume a lot of power. Your key fob remote will not be able to communicate with the receiver if its battery is low.

There is a problem with the key fob remote itself

There may be a problem with the key fob remote itself if the battery has been replaced and the remote is still not working. Key fobs can malfunction, or they can be programmed incorrectly for a car.

How do I reset my Ford key fob?

It is necessary to re-register your Ford key fob with the car if it does not operate following a battery change. These steps can be followed to do this:

  • Leave the key in the ignition and turn it to the “on” position
  • Press and release the lock button on the key fob
  • Turn the key to the “off” position and remove it from the ignition
  • The doors should now lock and then unlock, indicating that the reset is complete
