Many BMW keys typically use a CR2032 battery. This type of battery is a lithium coin cell that provides reliable power to the key fob. It is a widely available and commonly used battery that is affordable and easy to replace. The CR2032 battery has a long shelf life, and it’s known for its stability and durability.

If you’re unsure about changing the battery yourself or if your key fob requires a different procedure, it’s recommended to seek professional assistance.

Starting a BMW without a key battery can be a frustrating experience, especially if you’re in a hurry or far away from home. However, there are a few alternative methods you can try to get your BMW started. We will explore different ways to start a BMW without a key battery.
