If you’re experiencing any of these issues, it’s time to replace your key fob battery.

What You’ll Need

A small flat-head screwdriver or a plastic pry tool

Changing the Battery: A Step-by-Step Guide

Here’s how to change your BMW X5 key fob battery like a pro:

Locate the release button: Look for a small button on the back of your key fob. This button releases the physical key.
Release the physical key: Press the release button and gently slide the physical key out of the fob.
Open the key fob: Use the tip of your flat-head screwdriver or pry tool to carefully pry open the key fob casing. Start at the notch where the physical key was located.
Remove the old battery: Once the casing is open, you’ll see the old CR2032 battery. Gently pry it out.
Insert the new battery: Place the new CR2032 battery into the slot, ensuring the positive (+) side faces up.
Reassemble the key fob: Carefully align the two halves of the key fob casing and press them together until you hear a click.
Reinsert the physical key: Slide the physical key back into its slot on the key fob.
Test the key fob: Try locking and unlocking your car doors to ensure the new battery is working correctly.

Troubleshooting Tips

If your key fob still doesn’t work after replacing the battery, double-check that the new battery is properly installed and that the positive (+) side is facing up.
Make sure the battery contacts inside the key fob are clean. If not, you can clean them with a cotton swab and some rubbing alcohol.
If you’re still experiencing issues, consult your owner’s manual or contact your BMW dealership for assistance.

Avoid exposing your key fob to extreme temperatures or moisture.
Don’t stack heavy objects on top of your key fob.
