A dead key fob battery can be a major inconvenience, leaving you stranded and unable to unlock your Ford. Fortunately, changing the battery in your Ford key fob is a quick and easy process that most people can do themselves. This guide will walk you through the steps to replace your Ford key fob battery, get you back on the road, and help you avoid a costly trip to the dealership.
What You’ll Need to Change Your Ford Key Fob Battery
Before you begin, gather the following items:
- A new CR2032 battery: This is the most common type of battery used in Ford key fobs. You can find these batteries at most convenience stores, auto parts stores, and online retailers.
- A small flat-head screwdriver: This will be used to pry open the key fob.
- Optional: A small flashlight: This can be helpful if you are working in a dimly lit area.
Step-by-Step Guide to Change the Battery in a Ford Key Fob
Once you have gathered your materials, you can begin the process of replacing the battery in your Ford key fob. Here’s a step-by-step guide:
-
Locate the release button on the back of your key fob. This button is usually small and may have a key symbol next to it.
-
Press the release button and gently pull out the metal key. The key fob should now be separated into two halves.
-
Use the flat-head screwdriver to carefully pry open the key fob. There is usually a small notch where you can insert the screwdriver.
-
Locate the old battery. It will be a small, round, silver battery.
-
Gently remove the old battery and install the new battery. Make sure the positive (+) side of the battery is facing up.
-
Snap the two halves of the key fob back together. You should hear a click when they are securely fastened.
-
Test the key fob to make sure it is working properly. Try locking and unlocking your car doors, as well as using the panic button.
Why is My Ford Key Fob Not Working After Battery Replacement?
If your key fob isn’t working after you’ve replaced the battery, there are a few potential issues:
- The new battery is dead: Although rare, it’s possible you’ve picked up a dead battery. Try replacing it with a different CR2032 battery.
- The battery is installed incorrectly: Double-check that the positive (+) side of the battery is facing up.
- The key fob needs to be reprogrammed: Some Ford key fobs need to be reprogrammed after a battery change. You can usually find instructions on how to do this in your owner’s manual. If you’re unable to find the instructions or are uncomfortable reprogramming the key fob yourself, a dealership or automotive locksmith can do it for you.
Can a Dead Key Fob Battery Drain My Car Battery?
A dead key fob battery itself will not drain your car battery. Your car battery is responsible for powering the vehicle’s electrical system, while the key fob battery only powers the key fob’s signal transmission.
How Long Does a Ford Key Fob Battery Last?
The battery in your Ford key fob typically lasts between 3 to 5 years, depending on usage and environmental factors. Signs that your key fob battery is dying include a decreased signal range (requiring you to be closer to the car for it to respond) or the key fob needing to be pressed multiple times before the car responds.
Preventing Future Ford Key Fob Battery Issues
- Avoid extreme temperatures: Extreme heat or cold can shorten the lifespan of your key fob battery.
- Don’t let the battery drain completely: If you notice your key fob’s signal range is decreasing, it’s a good indication that the battery is getting low and should be replaced soon.
