Why is My 2008 BMW Key Fob Battery Dying?

Just like your car battery, your key fob battery has a limited lifespan. On average, you can expect it to last anywhere from 3 to 5 years. However, several factors can impact its longevity:

Frequency of use: The more you use your key fob, the faster the battery drains.
Extreme temperatures: Both hot and cold weather can shorten battery life.
Age: Over time, all batteries lose their ability to hold a charge effectively.

What Kind of Battery Does a 2008 BMW Key Fob Take?

Most 2008 BMW key fobs use a CR2032 battery. This small, coin-shaped battery is readily available at most drugstores, supermarkets, and online retailers.

How Do I Change the Battery in My 2008 BMW Key Fob?

You won’t need a mechanic for this one! Changing the battery in your 2008 BMW key fob is a simple DIY task. Here’s a step-by-step guide:

Locate the battery compartment: On the back of your key fob, you’ll find a small release button or slider.
Open the compartment: Press the button or slide the release mechanism to open the battery compartment.
Remove the old battery: Carefully pry out the old CR2032 battery. Note the orientation (+/-) for installing the new one.
Insert the new battery: Place the new battery into the compartment, ensuring the positive (+) side faces up, just like the old battery.
Close the compartment: Snap the battery compartment cover back into place.
Test your key fob: Try locking and unlocking your car to ensure the new battery is working correctly.

Still Having Trouble?

Sometimes, what seems like a simple battery issue can be more complex. If you’ve replaced the battery and your 2008 BMW key fob still isn’t working correctly, you might need to:

Reinitialize your key fob: Your BMW owner’s manual will have instructions on how to reprogram your key fob after a battery change.
Check for other issues: There could be a problem with your key fob’s circuitry or your car’s receiver. In this case, it’s best to consult a qualified BMW technician.
