BMW X5 Key Battery Replacement Guide (2006-2013)

Introduction to BMW X5 Key Battery Replacement

The BMW X5 is a popular luxury SUV that has been around for many years. From 2006 to 2013, the E70 variation of the BMW X5 used a specific type of key fob. This guide focuses on replacing the battery for the Comfort Access version of the key remote.

Comfort Access keys have a distinctive outline on the back, making them easy to identify. If your key lacks this outline, you have a non-Comfort Access key, which requires a different, more complex process involving soldering.

Identifying Your Key Type

To determine whether you have a Comfort Access key, flip the key over. Look for a small outline on the backing. If present, you have a Comfort Access model. If not, you have a non-Comfort Access key.

This guide will show you how to replace the battery in the Comfort Access model. For non-Comfort Access keys, refer to specialized tutorials that cover the additional steps required.

Tools and Materials Needed

• CR2032 battery
• Small Phillips screwdriver

The CR2032 battery is a common watch battery that is readily available. Ensure you have one on hand before starting the replacement process.

Step-by-Step Battery Replacement

Step 1: Remove the Valet Key

First, remove the valet key from the key fob. This will give you access to the internal components.

The valet key is a smaller key within the main key fob. Slide it out carefully to proceed.

Step 2: Access the Battery Compartment

With the valet key removed, you’ll see two small holes. Focus on the middle hole, located next to the outline on the back of the key fob.

Use a small Phillips screwdriver to gently pry the back cover off. Work slowly to avoid damaging the key fob.

Step 3: Remove the Old Battery

Once the back cover is off, you’ll see the old CR2032 battery. Use the screwdriver or a similar tool to pry the old battery out.

Be cautious not to damage any internal components while removing the battery.

Step 4: Insert the New Battery

Take the new CR2032 battery and ensure the text is facing you. Insert it into the battery compartment.

Press down firmly to ensure the battery is securely in place.

Step 5: Reassemble the Key Fob

Once the new battery is in place, reattach the back cover. Press it firmly until it snaps into place.

Finally, reinsert the valet key into the key fob. Your key is now ready to use.

Common Issues and Troubleshooting

If your key fob doesn’t work after replacing the battery, double-check the battery orientation. The text on the battery should face you during insertion.

Ensure the back cover is securely attached. A loose cover can prevent the key fob from functioning correctly.

If problems persist, consider consulting a professional or referring to specialized guides for further troubleshooting.
