A dead key fob battery can be a major inconvenience, especially when you’re in a hurry. Fortunately, replacing the battery in your BMW key fob is a quick and easy process that can be done at home with just a few tools. In this article, we’ll walk you through the steps of how to replace the battery in a BMW key fob, so you can get back on the road in no time.
What You’ll Need
Before you get started, gather the following items:
- A new CR2032 battery
- A small flat-head screwdriver
- Your BMW key fob
Pro Tip from John Smith, Senior Automotive Electrician: “Always ensure you are using a brand new, high-quality CR2032 battery for optimal performance and lifespan of your key fob.”
Step-by-Step Guide
1. Locate the Release Button: Examine the back of your BMW key fob and find the small release button or slot. This button is usually located near the key ring.
2. Open the Key Fob: Gently insert the flat-head screwdriver into the release slot and apply slight pressure to release the casing. The key fob should pop open, revealing the battery compartment.
3. Remove the Old Battery: Carefully remove the old CR2032 battery from the compartment. You can use the screwdriver or your fingers to pry it out gently.
4. Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side is facing up. Most key fob compartments will have markings indicating the correct battery orientation.
5. Close the Key Fob: Align the two halves of the key fob casing and press them together firmly until you hear a click. This indicates that the casing is securely closed.
6. Test the Key Fob: Test all the buttons on your key fob (lock, unlock, trunk release) to ensure the new battery is working correctly.
Expert Insight from Emily Carter, Certified Automotive Technician: “After replacing the battery, ensure the key fob casing is tightly sealed to prevent moisture or debris from entering and damaging the electronics.”
Troubleshooting Tips
If your BMW key fob is still not working after replacing the battery, try the following:
- Check Battery Orientation: Ensure that the new battery is inserted correctly with the positive (+) side facing up.
- Clean the Battery Contacts: Use a cotton swab and rubbing alcohol to clean the battery contacts inside the key fob.
- Try a Different Battery: In rare cases, the new battery you purchased may be faulty. Try installing a different CR2032 battery.
If you’ve tried all of the above steps and your BMW key fob is still not functioning properly, you may have a more serious issue that requires professional diagnosis and repair. Consider contacting your local BMW dealership or a qualified automotive locksmith.
