How to Change Key Fob Battery in a 2001 BMW

Changing the battery in your 2001 BMW key fob is a simple process that can save you time and money. A dead key fob battery can leave you stranded, so knowing how to replace it yourself is a valuable skill. This guide will walk you through the steps involved, addressing common issues and offering helpful tips.

Replacing your BMW key fob battery is a straightforward task that most people can handle themselves. By understanding the process and having the right tools, you can avoid a trip to the dealership and get back on the road quickly. There are a few different types of key fobs for 2001 BMW models, so we’ll cover the most common ones.

Identifying Your 2001 BMW Key Fob

Before you start, it’s crucial to identify the type of key fob you have. This will determine the specific steps for battery replacement. 2001 BMWs typically had two main key fob styles: the diamond-shaped key with integrated remote, and the rectangular remote with a separate valet key.

Diamond-Shaped Key Fob with Integrated Remote

This key fob is easily recognized by its diamond shape and integrated key blade. The battery compartment is usually located on the side or back of the fob.

Rectangular Key Fob with Separate Valet Key

The rectangular key fob is larger and has a separate valet key. The battery compartment for this type is typically accessed by sliding or prying open a section of the fob.

Gathering the Necessary Tools

Once you’ve identified your key fob, gather the necessary tools. You’ll need a small flathead screwdriver or a similar tool to pry open the key fob, and a replacement battery. The most common battery type for 2001 BMW key fobs is the CR2032.

Choosing the Right Battery

Make sure you purchase a high-quality CR2032 battery. Cheap batteries can leak and damage your key fob. It’s best to stick with reputable brands.
