Changing the battery in your 1999 Ford Explorer key fob is a quick and easy process that can save you time and money. This guide will walk you through each step, ensuring you’re back on the road with a functioning key fob in no time.

Understanding Your 1999 Ford Explorer Key Fob

Before we dive into the battery replacement process, it’s helpful to understand the components of your key fob. The 1999 Ford Explorer typically uses a simple key fob with a few buttons for locking, unlocking, and potentially panic functions. Inside this fob lies a small battery that powers these functions. Over time, this battery will weaken and eventually die, requiring a replacement. Knowing how to perform this simple task can prevent the inconvenience of a non-functional key fob.

Gathering Your Tools and Materials

You’ll need only a few items to change your 1999 Ford Explorer key fob battery:

A fresh CR2032 battery. This is the most common battery type for these key fobs.
A small flathead screwdriver or a similar tool for prying open the key fob casing.
Optionally, a small container or tray to hold the small parts of your key fob to prevent loss.

Step-by-Step Guide: How to Change Battery in 1999 Ford Explorer Key Fob

Here’s a detailed guide to changing the battery:

Locate the seam: Carefully examine your key fob for a small seam or groove along the edge. This seam is where the two halves of the key fob casing connect.
Insert the screwdriver: Gently insert the flathead screwdriver into the seam. Apply gentle pressure to pry the two halves apart. Be careful not to damage the plastic casing.
Separate the halves: Once the initial separation is made, carefully work your way around the perimeter of the key fob, separating the two halves completely.
Identify the battery: Inside the key fob, you’ll see the CR2032 battery. It’s usually held in place by a small clip or pressure.
Remove the old battery: Gently pry the old battery out of its compartment using your screwdriver or fingernail. Avoid excessive force to prevent damage.
Install the new battery: Insert the new CR2032 battery into the compartment, ensuring the positive (+) side is facing upwards, as it was with the old battery.
Reassemble the key fob: Align the two halves of the key fob casing and press them together firmly until they snap back into place.
Test the key fob: Try locking and unlocking your vehicle to ensure the new battery is working correctly.

Troubleshooting Your 1999 Ford Explorer Key Fob

Sometimes, even after replacing the battery, your key fob might not work. Here are some common issues and solutions:

Check the battery orientation: Ensure the new battery is installed correctly with the positive (+) side facing upwards.
Clean the battery contacts: Use a cotton swab and rubbing alcohol to clean the battery contacts inside the key fob. This can remove any corrosion that might be interfering with the connection.
Try reprogramming the key fob: In some cases, you may need to reprogram the key fob to your vehicle after replacing the battery. Refer to your owner’s manual for specific instructions on how to do this. It typically involves a sequence of actions with the ignition key and door locks.
