Signs Your Key Fob Battery Needs Replacing

Just like your car battery, your key fob battery has a limited lifespan. Here are some telltale signs that it might be time for a new one:

Intermittent Functioning: Does your key fob sometimes work and sometimes not? This inconsistency is another strong indicator of a dying battery.
Dashboard Warning Light: Some BMW models may display a warning message on the dashboard when the key fob battery is low.
Physical Damage: Inspect your key fob for any cracks, water damage, or other physical issues that could be affecting its performance.

How to Replace Your 2014 BMW 3 Series Key Fob Battery: A Step-by-Step Guide

Replacing the battery in your key fob is a surprisingly straightforward process. Here’s a step-by-step guide:

Locate the Release Button: Look for a small button or switch on the back of your key fob. This will typically be near the key ring.
Release the Emergency Key: Press the release button and gently slide out the emergency key blade.
Open the Key Fob: Use the emergency key blade or a small flat-head screwdriver to carefully pry open the key fob casing. Start at the notch where the emergency key was located.
Remove the Old Battery: Carefully remove the old CR2032 battery. Note the position of the positive (+) and negative (-) sides.
Insert the New Battery: Place the new CR2032 battery into the key fob, ensuring the positive (+) side is facing up, just as the old battery was positioned.
Reassemble the Key Fob: Align the two halves of the key fob casing and press them together until you hear a click, indicating it’s securely closed.
Reinsert the Emergency Key: Slide the emergency key back into its slot.
Test Your Key Fob: Try locking and unlocking your car to ensure the new battery is working correctly.

Pro Tip from Mike Thompson, Certified BMW Technician: “When replacing the battery in your key fob, be careful not to touch the battery terminals with your fingers. This can reduce the battery life.”

What if My Key Fob Still Doesn’t Work?

Key Fob Programming: In some cases, you may need to reprogram your key fob to your car after replacing the battery. Refer to your owner’s manual for specific instructions.
Key Fob Antenna: The antenna in your key fob or car could be faulty, preventing communication between the two.
Other Electronic Issues: Other electronic issues with your car could be interfering with the key fob’s signal.
