Identifying Your BMW Key Fob Type
BMW has released several key fob designs over the years. Identifying your specific key fob type is the first step to changing the battery correctly. Common types include the standard key fob, the display key, and the comfort access key. Each type has a slightly different battery replacement procedure.
Standard Key Fob Battery Replacement
The standard key fob is the most common type. To change the battery, you’ll need a small flathead screwdriver and a CR2032 battery. Begin by inserting the flathead screwdriver into the small slot on the side of the key fob. Gently pry open the key fob to reveal the battery compartment. Remove the old battery and replace it with the new CR2032 battery, ensuring the positive (+) side is facing upwards. Finally, snap the key fob back together.
Display Key Battery Replacement
The display key has a small LCD screen that shows information like remaining fuel and range. The battery replacement process is similar to the standard key fob, but it uses a different battery type, typically a CR2450. Follow the same steps as the standard key fob, using the flathead screwdriver to open the fob and replace the CR2450 battery.
