Different BMW Key Fob Styles and Battery Replacement
BMW offers various key fob designs, each with a slightly different battery replacement procedure. While the overall process is similar, understanding the nuances of your specific key fob is crucial. This section will explore the most common BMW key fob types and detail the steps involved in changing their batteries.
The Diamond Key Fob
The diamond key fob is a popular design recognized by its distinct shape. To change the battery, you’ll typically find a small release button or slot on the side. Pressing this button allows you to separate the key fob into two halves, revealing the battery compartment.
The Rectangular Key Fob
The rectangular key fob, often found in older BMW models, has a slightly different approach to battery replacement. Usually, there’s a small sliding tab or a release button that you need to manipulate to access the battery compartment.
Step-by-Step Guide: How to Change Your BMW Key Fob Battery
Regardless of the key fob style, the overall process is relatively simple. Here’s a general guide:
- Identify Your Key Fob Type: Determine whether you have a diamond, rectangular, or another style of key fob. This will help you follow the specific instructions for your model.
- Gather Your Tools: You’ll typically need a small flat-head screwdriver or a similar tool to pry open the key fob. A replacement CR2032 battery is also required. Ensure you have the correct battery type as using an incorrect battery can damage your key fob.
- Locate the Release Mechanism: Find the release button, slot, or tab on your key fob. This is usually located on the side or back of the fob.
- Open the Key Fob: Carefully insert the flat-head screwdriver into the release mechanism and gently pry open the key fob. Be careful not to damage the plastic casing.
- Remove the Old Battery: Once the key fob is open, locate the battery compartment. Gently remove the old battery, noting its orientation.
- Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring it’s in the same orientation as the old battery. Press it firmly into place.
- Close the Key Fob: Align the two halves of the key fob and press them together until they click shut. Test the key fob buttons to ensure they are working correctly.

Troubleshooting and Common Issues
Sometimes, even after replacing the battery, your key fob might not function correctly. Here are some common issues and how to address them:
-
Key Fob Still Not Working: Double-check that the new battery is correctly installed and is making proper contact. Try using a different new battery to rule out a faulty battery. If the issue persists, there might be a more serious problem with the key fob itself, and you may need to consult a BMW specialist.
-
Key Fob Intermittently Working: This could indicate a loose connection within the key fob. Try cleaning the battery contacts with a cotton swab and alcohol. If the problem continues, you might need to have the key fob inspected by a professional.
John Smith, a certified BMW technician with over 20 years of experience, advises, “Always use a high-quality CR2032 battery for optimal performance and longevity.” He also recommends, “If you are unsure about any step in the process, it is always best to consult your owner’s manual or contact a qualified technician.”
