Identifying the Right Battery for Your 2017 BMW Key Fob

Before you start, it’s crucial to identify the correct battery type for your specific 2017 BMW model. Using the wrong battery can damage your key fob. Most 2017 BMW key fobs use a CR2032 3V lithium battery. However, it’s always best to double-check your owner’s manual or search online using your specific BMW model and year (e.g., “battery for key fob bmw x3”) to ensure you purchase the right one.

“Choosing the correct battery is the first and most important step,” says John Davis, Senior Automotive Technician at Bavarian Auto Experts. “Using an incorrect battery can lead to malfunction or even damage to the key fob’s internal circuitry.”

Step-by-Step Guide to 2017 BMW Key Fob Battery Replacement

Follow these simple steps to replace your 2017 BMW key fob battery:

1. Locate the release button: This is usually a small button or slot on the side of your key fob.
2. Release the emergency key: Carefully insert the emergency key (found within your key fob) into the release slot and gently pry open the key fob casing.
3. Access the battery compartment: Once the casing is open, you should see the battery compartment.
4. Remove the old battery: Gently pry the old battery out of its compartment using a small flathead screwdriver or a similar tool. Be careful not to damage the contacts.
5. Insert the new battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side is facing upwards.
6. Reassemble the key fob: Carefully snap the two halves of the key fob casing back together.
7. Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.

Troubleshooting Common Issues

Sometimes, even after replacing the battery, your key fob might not work. Here are some common issues and their solutions:

• Key fob still not working: Ensure the new battery is properly seated and the contacts are clean.
