How do you replace a BMW key battery?
I’ve had my BMW for a few years now and I’m starting to have issues with my key fob. It doesn’t seem to be able to unlock my car from a distance. How can I replace my BMW key battery?

Most car key batteries last for about three or four years before needing a new battery. Depending on the type of
BMW
key you have, you may not need to replace the battery. If you have a non-comfort access key, all you’ll need to do is go for a long drive as the key recharges through the ignition. If you have a smart key or comfort access key and can open your key fob, you will need to replace the battery by following these steps:
- Buy a new CR2032 battery.
- Press the tab on the key fob to release the metal key.
- Use the key or a flathead screwdriver to open the battery cover.
- Remove the dead battery and put the new one in its place.
- Close your key fob and return the key.
Once you have successfully replaced or recharged your battery, you should have no trouble using it effectively from a distance. If you’re interested in more car-related convenience, be sure to check out the
Jerry
app and see how you can save hundreds of dollars on your car insurance. After you download Jerry, answer a handful of questions that will take you roughly 45 seconds to complete and you’ll immediately get car insurance quotes for coverage similar to your current plan.
