Ready to tackle this yourself? Here’s a step-by-step guide to replacing your 2016 BMW 4 Series key fob battery:
- Locate the release button: Look for a small button on the back of your key fob. It’s usually located near where the metal key inserts.
- Release the metal key: Press the release button and gently pull out the metal key from the fob.
- Open the key fob casing: Use the flat-head screwdriver to carefully pry open the casing. Start at the notch where the metal key was inserted, applying gentle pressure until the two halves separate.
- Remove the old battery: You’ll see the CR2032 battery inside. Carefully remove it by prying it up from the side with your fingernail or the flat-head screwdriver.
- Insert the new battery: Place the new CR2032 battery in the slot, making sure the positive (+) side is facing up.
- Close the key fob: Align the two halves of the casing and press them firmly together until you hear a click, indicating the fob is securely closed.
- Reinsert the metal key: Slide the metal key back into its slot until it locks in place.
- Test your key fob: Try locking and unlocking your car doors to ensure the new battery is working correctly.
Troubleshooting Tips
If you’ve replaced the battery and your key fob is still not responding, don’t panic. Here are a few things to check:
- Battery orientation: Ensure you inserted the new battery with the positive (+) side facing up.
- Battery contacts: Examine the battery contacts inside the key fob for any dirt or corrosion. You can clean them gently with a cotton swab and some rubbing alcohol.
- Key fob programming: In rare cases, you might need to reprogram your key fob after a battery replacement. Refer to your owner’s manual for instructions specific to your 2016 BMW 4 Series model.
“Many people overlook the importance of routine maintenance for their key fobs,” says John Smith, Senior Automotive Technician at XYZ Auto. “Just like your car battery, your key fob battery needs replacement every few years to ensure optimal performance.”
