Having trouble with your 2003 BMW 325xi key fob? Before you schedule a trip to the dealership, it could be something as simple as a dead battery. Replacing the key fob battery on your own is a fairly straightforward process that can save you both time and money. Here’s a quick guide to get you back on the road in no time.
What You’ll Need:
- A new CR2032 battery (you can usually find these at electronics stores, auto parts stores, or even your local supermarket)
- A small flat-head screwdriver
- Your 2003 BMW 325xi key fob
Replacing the Battery:
-
Open the key fob: Locate the small release button on the back of your key fob. Gently press the button and slide the back cover off to reveal the battery compartment.
-
Remove the old battery: Carefully pry out the old battery. Note the position of the positive (+) side of the battery for correct replacement.
-
Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side is facing the same direction as the old battery.
-
Close the key fob: Align the back cover and snap it back into place.
-
Test the key fob: Make sure the buttons on your key fob are working correctly by locking and unlocking your car doors.
Pro Tip from John Miller, ASE Certified Master Technician: “When replacing the battery, avoid touching the terminals with your fingers. This can transfer oils and reduce the lifespan of the new battery. If you do accidentally touch the terminals, simply wipe them clean with a dry cloth.”
Troubleshooting:
- Key fob still not working? Double-check that you’ve inserted the new battery correctly, ensuring the positive (+) side is facing up.
- Key fob working intermittently? This could indicate a weak battery or a problem with the key fob itself. Try a new battery first. If the problem persists, you may need to have your key fob inspected by a qualified technician.
