Signs Your 2004 BMW X5 Key Fob Battery Needs Replacing
Before you find yourself stuck in a parking lot, your X5 will usually give you some warning signs that your key fob battery is fading:
- Decreased Range: You find yourself standing closer and closer to your car to get it to lock or unlock.
- Intermittent Functioning: The key fob works sometimes, but not others, leading to a frustrating game of “try it again.”
- Dashboard Warning Light: Your X5 may display a warning message indicating a low key fob battery.
- Slow Response: Buttons on the key fob require multiple presses or a longer hold for the vehicle to respond.
How to Replace Your 2004 BMW X5 Key Fob Battery
Don’t worry, replacing the battery in your 2004 BMW X5 key fob is relatively simple and doesn’t require a trip to the dealership. Here’s what you need to do:
What You’ll Need:
- A new CR2032 battery (easily found at most grocery stores, pharmacies, and online retailers)
- A small flat-head screwdriver
Instructions:
- Open the Key Fob: Locate the small groove on the side of the key fob. Gently insert the flat-head screwdriver and pry open the casing.
- Remove the Old Battery: Carefully remove the old CR2032 battery. Note the orientation of the positive (+) and negative (-) sides.
- Insert the New Battery: Place the new battery into the compartment, matching the same orientation as the old battery.
- Reassemble the Key Fob: Snap the two halves of the key fob casing back together.
Pro Tip: While the key fob is open, you can clean the contacts with a cotton swab and rubbing alcohol for optimal performance.
