How to change battery for bmw key

Having trouble with your BMW key? One common issue could be a drained battery. If your key stops working or you notice a decrease in signal strength, it may be time to replace the battery. But don’t worry, it’s a simple process that you can do yourself!

The first step is to determine what type of key you have. BMW keys can be either standard remote keys or comfort access keys. The process for changing the battery differs slightly depending on the type. Standard remote keys have a key blade that you can use to manually unlock your car, while comfort access keys do not have a key blade.

Now, let’s get started with the battery replacement. For standard remote keys, locate the small groove on the side of the key and use a small flat-head screwdriver to gently pry it open. Inside, you will find the old battery. Take note of its orientation, then carefully remove it and replace it with a new one. Make sure to align the new battery in the same orientation as the old one.
