Ford key fob not working after battery change

The Ford key fob is a great convenience, but it can also be a source of frustration when it doesn’t work properly. If your Ford key fob isn’t working after you’ve changed the battery, there are a few things you can try to get it working again.

This is a common problem that many Ford owners face. In this blog post, we will discuss the causes of this problem and how to fix it.

Your Ford key fob not working after a battery change is probably caused by the battery change itself. The key fob must be reset to the car after replacing the battery in the key fob remote, as the key was erased when the battery was changed. This is why nothing is operating with your key fob remote.

You’ll need to reprogram the remote back to the vehicle once you’ve replaced the battery in your key fob remote.

A key fob is a small, hand-held remote that can be used to lock and unlock your car doors from a distance. It can also be used to activate the panic alarm on your car. Key fobs typically have buttons for locking and unlocking the doors, as well as a button for activating the panic alarm.

How A Key Fob Works

A key fob works by sending a radio signal to a receiver that is located inside the car. The receiver then activates the locks or the alarm.

Key fobs use rolling codes, which means that each time you press a button on the remote, it sends a different code to the receiver. This makes it difficult for someone to intercept the signal and unlock your car without your permission.

Reasons Why Your Ford Key Fob May Not Work After A Battery Change?

As we mentioned before, one of the most common reasons why your Ford key fob might not be working after you’ve changed the battery is because it needs to be reset.

If you’ve replaced the battery in your key fob remote and it’s still not working, the reasons could be one of the following:

The key fob remote was not properly programmed for the vehicle

The key fob must be properly programmed to the vehicle in order for it to work. If you’ve replaced the battery in your key fob remote and it’s still not working, it’s possible that the remote was not properly programmed for the vehicle.

The receiver is not working

The receiver is what receives the signal from the key fob remote and activates the locks or the alarm. If the receiver is not working, then the key fob will not be able to communicate with it and it will not work.

The battery in the key fob remote is low

Even if you’ve just replaced the battery in your key fob remote, it’s possible that the battery is already low. Key fobs use a lot of power and the batteries don’t last very long. If the battery in your key fob remote is low, it will not be able to communicate with the receiver.

There is a problem with the key fob remote itself

When you’ve replaced the battery in your key fob remote and it’s still not working, there may be a problem with the key fob remote itself. It’s possible that the key fob is damaged or that it was not properly programmed for the vehicle.

How do I reset my Ford key fob?

In case your Ford key fob isn’t working after you’ve changed the battery, you’ll need to reset it to the vehicle. This can be done by following these steps:

1. Start with the key out of the ignition and all doors closed
2. Insert and remove the key from the ignition six times within ten seconds
3. Leave the key in the ignition and turn it to the “on” position
4. Press and release the lock button on the key fob
5. Turn the key to the “off” position and remove it from the ignition
6. The doors should now lock and then unlock, indicating that the reset is complete

When you’ve followed these steps and your Ford key fob still isn’t working, it’s possible that there is a problem with the key fob itself. You may need to take it to a dealer or locksmith to have it programmed or replaced.
