From the comfort of your garage or driveway, follow these steps to ensure your BMW key fob functions flawlessly. Let’s dive into how you can replace the battery and keep your BMW remote ready for every journey.
Identifying Your BMW Key Fob Type
First, identify your BMW key fob type. Each model, whether it’s the 1 series, 2 series, 5 series, 7 series, X1, X3, X5, or X6, may have a different key fob. This step is crucial as it determines the battery type needed and the replacement process.
Tools and Materials Needed
You will need a new battery, which could be a CR2032 or a CR2450, and a screwdriver. Sometimes, you might also use the valet key to open the key fob.
Step-by-Step Battery Replacement for Smart Key
- Locate a new CR2450 battery.
- Remove the metal key blade from the key fob.
- Take off the back cover.
- Carefully remove the old battery.
- Insert the new one securely.
Step-by-Step Battery Replacement for Comfort Access Key
- Find a new CR2032 battery.
- Press the small tab on the key fob to access the valet key.
- Use the valet key or a flathead screwdriver to open the key fob.
- Replace the old battery with the new CR2032 battery.
- Ensure the key fob is securely closed.
Handling Non-Comfort Access Key Battery Replacement
For non-comfort access keys, the process differs. These keys have rechargeable batteries that charge automatically when in the engine. If your key won’t open, it might be because it’s a non-comfort access type. You can’t simply change or charge the battery yourself in this case.
It’s recommended to contact our service department for assistance. Our trained technicians can open the key fob for you, ensuring the battery is correctly replaced without damaging the fob.
Replacing Battery in Sleek Slant Shaped Key
The sleek slant-shaped key, often found in newer BMW models, requires a CR2032 battery. First, push the button to release the valet key. Then, use it to open the battery compartment. Replace the old battery with the new one, ensuring it fits snugly and securely.
It’s crucial to follow the correct direction when inserting the new battery to prevent damage. After replacement, make sure the key fob is closed tightly.
Special Considerations for Diamond Key Fob
The diamond key fob is a bit tricky. Its battery is not meant to be user-replaceable. However, if you’re curious and handy with tools, it’s possible to replace them. This involves cutting the fob open and soldering in a new battery, a task best left to professionals.
We don’t recommend attempting this without proper knowledge and tools. Contact our service centre for help. Our experts have the right tools and experience to handle this delicate procedure.
