What You Will Need
Before you begin, make sure you have the following items handy:

- Small flat-head screwdriver or a small, thin object like a coin or a paperclip
- Soft cloth or towel
Step 1: Identify Your Key Fob Model
BMW key fobs come in different models, and the battery replacement process may vary slightly depending on the model you have. The most common key fob models for BMW vehicles include the diamond-shaped key fob and the rectangular-shaped key fob. To ensure you have the correct instructions for your specific key fob model, check your owner’s manual or consult a BMW dealership.
Step 2: Prepare a Safe Work Environment
Before you start working on your key fob, it’s important to create a safe work environment to prevent any damage to the key or your vehicle. Find a clean, well-lit, and stable surface to work on. Place a soft cloth or towel on the surface to protect the key fob from scratches or accidental drops.
Step 3: Open the Key Fob
To access the battery compartment, you’ll need to open your BMW key fob. The process may vary slightly depending on the key fob model, so refer to your owner’s manual or consult a BMW dealership for specific instructions. In general, follow these steps:
- Locate the small slot or groove on your key fob. It is usually located on the edge or side of the key fob.
- Insert a small flat-head screwdriver, coin, or another thin object into the slot.
- Gently twist or pry the key fob cover to separate it from the main body. Be careful not to apply excessive force to avoid damaging the key fob.
Step 4: Remove the Old Battery
With the key fob open, you can now remove the old battery. Take note of the battery’s orientation before removing it to ensure you insert the new battery correctly. Follow these steps:
- Locate the battery inside the key fob. It is typically a small, round battery.
- Use your thumb, a small flat-head screwdriver, or a similar object to gently push the battery out of its compartment.

Step 5: Insert the New Battery
With the old battery removed, it’s time to insert the new battery into the key fob. Make sure you have the correct replacement battery for your specific key fob model. Follow these steps:
- Take the new battery and check its orientation. Look for any markings or engravings that indicate which side should face up.
- Place the new battery into the battery compartment, ensuring it sits securely in place.
- Apply gentle pressure to the battery to ensure it is fully inserted and making proper contact.
Step 6: Close the Key Fob
Now that the new battery is in place, it’s time to close the key fob. Make sure the key fob cover is properly aligned with the main body before closing it. Follow these steps:
- Hold the key fob cover and main body together, aligning the two pieces.
- Gently press them together until you hear a click or feel the key fob securely snap shut.
- Inspect the key fob to ensure there are no gaps or misalignments.
Step 7: Test the Key Fob
After changing the battery, it’s crucial to verify that your key fob is functioning properly. Test the key fob by locking and unlocking your BMW, as well as starting the engine. If the key fob is still not working, double-check your battery installation or consider replacing the key fob.
