Tools and Materials Needed

Before you start, make sure you have the following tools and materials:

• Small Flat-Head Screwdriver

You can purchase the CR2032 coin battery online or at most electronics stores. Having a small flat-head screwdriver on hand will make the process easier.

Step-by-Step Guide to Replacing the Battery

Step 1: Remove the Valet Key

The first step is to remove the valet key from your key fob. To do this, depress the side of the key fob near the top. This will release the valet key.

Step 2: Locate the Battery Compartment

Once the valet key is removed, you will see a small hole next to the valet key slot. This hole is the perfect size for a small flat-head screwdriver or even the valet key itself.

Step 3: Open the Battery Compartment

Insert the flat-head screwdriver or the valet key into the hole and use it as leverage to pop off the back cover of the key fob. This will give you access to the internal battery compartment.

Step 4: Remove the Old Battery

Inside the battery compartment, you will find a CR2032 battery. To remove it, gently pop it out from the top. There are two holdings at the top and a base part that keep the battery in place.

Step 5: Insert the New Battery

Take the new CR2032 battery and place it into the compartment. Make sure to insert the bottom part first to avoid the battery flying out. Once it is securely in place, you can proceed to the next step.

Step 6: Reassemble the Key Fob

Place the back cover of the key fob back on by aligning the curved part with the base first. Once it is in place, press down to snap it back together. Finally, reinsert the valet key.

Conclusion

Replacing the battery in your BMW X4 key fob is a simple process that can be done in just a few minutes. By following these steps, you can ensure that your key fob remains functional and reliable.

Remember to dispose of the old battery properly and keep a spare CR2032 battery on hand for future replacements.
