FAQ:

Q: Where are the batteries in a BMW key fob?

A: Non-rechargeable batteries are often found in key fobs with BMW keyless start. Rechargeable batteries are found in some key fobs that need to be inserted into an ignition slot in your car, like in E60 and E90 vehicles without Comfort Access. In this case, the ignition slot doubles as a charger, topping up the battery while you drive.

Q: How do you change the battery in a BMW?

A: To replace your Comfort Access BMW Key Battery, you will need a CR2032 battery. If your key won’t open, you may have the non-comfort access version which has a built-in rechargeable battery. After the valet key is removed, you will notice a small access port on the key fob. Use the valet key or a flat screwdriver to remove the key battery cover.

Q: Where is the battery on a BMW remote?

A: Turn the BMW remote over. Look at the back of your BMW key. The BMW key battery is located under the back cover. Remove the battery cover.

Q: What do you do with a BMW FOB?

A: Pressing a button at the base of the fob lets you remove the key, which can be used to unlock your BMW’s door. This removable key blade is sometimes known as a “surfer’s key”; leave your fob out of sight inside your vehicle, and just take the internal key blade in situations when you’re likely to worry about waterproofing.
