The Discovery 4 is a fantastic SUV, known for its ruggedness and off-road capabilities. However, like any vehicle, it can face minor inconveniences, such as a dying key fob battery. This can leave you stranded, unable to unlock your vehicle. Fear not! Changing the battery in your Discovery 4 key fob is a simple process that can be done in minutes. This guide will walk you through the steps, ensuring you’re back on the road in no time.

Gather Your Supplies

Before you begin, gather the following:

• A new CR2032 battery: This is the standard battery used in most Discovery 4 key fobs.
• A small flathead screwdriver: You’ll need this to pry open the key fob.
• A clean cloth: This will be helpful for wiping away any dust or debris.

Identifying the Key Fob Battery Compartment

The first step is to locate the battery compartment on your Discovery 4 key fob. It’s usually found on the back of the fob, but its exact location may vary depending on the model year.

• Look for a small, recessed area: This area will often have a small, sliding tab or a small button that you need to press to open the compartment.
• Check the edges of the key fob: Sometimes, the battery compartment is located along the edges, particularly near the key blade.

Opening the Key Fob

Once you’ve located the battery compartment, you’ll need to open it.

• Look for a small tab or button: If there’s a tab or button, gently slide it or press it to release the back cover of the key fob.
• Use a flathead screwdriver: If there’s no button or tab, carefully insert the flathead screwdriver into a small gap on the key fob’s back. Pry open the back cover gently, taking care not to damage the plastic.

Replacing the Battery

With the back cover open, you’ll see the old battery.

• Remove the old battery: Gently lift the old battery out of its compartment.
• Insert the new battery: Carefully place the new CR2032 battery into the compartment, ensuring the positive (+) side of the battery faces up.
• Close the back cover: Securely close the back cover of the key fob, making sure it clicks into place.

Testing the Key Fob

After replacing the battery, it’s crucial to test the key fob to ensure it’s working correctly.

• Press the unlock button: The key fob should unlock your Discovery 4.
• Press the lock button: The key fob should lock the vehicle.
• Test the panic button: If your key fob has a panic button, press it to ensure it activates the alarm.

If the key fob doesn‘t respond, double-check that the new battery is correctly inserted. If the issue persists, you may need to consult a qualified mechanic.

Troubleshooting Common Problems

While changing the battery is generally straightforward, you might encounter some minor issues.

• The battery compartment won’t open: If you can’t open the battery compartment, try using a different screwdriver or applying a bit more pressure. However, be careful not to damage the key fob.
• The key fob doesn’t work after replacing the battery: Double-check that the battery is correctly inserted and that the positive (+) side is facing up. If the issue persists, try cleaning the battery contacts with a clean cloth.
• The key fob intermittently works: If the key fob works sometimes but not others, it could indicate a more significant issue with the key fob itself. In this case, you may need to contact a qualified mechanic or your local Land Rover dealership.
