2013 BMW 5 Series Key Fob Battery Replacement: A Quick Guide

Experiencing a spotty connection with your 2013 BMW 5 Series key fob? Before you schedule a trip to the dealership, a dead battery might be the culprit. Replacing it is a surprisingly simple DIY task that can save you time and money. In this guide, we’ll walk you through the process step-by-step.

Do I Need a New Key Fob Battery?

Here are a few telltale signs that your 2013 BMW 5 Series key fob battery needs replacing:

Decreased Range: Are you finding yourself standing closer and closer to your car to get it to unlock? This is a prime indicator of a weakening battery.
Intermittent Functioning: If your key fob only works sporadically, the battery is likely on its last legs.
Warning Messages: Your BMW may display a “Key Fob Battery Low” warning on the dashboard.

What You’ll Need:

A New Battery: Grab a CR2032 battery. These are readily available at most grocery stores, pharmacies, and online retailers. For guaranteed compatibility, consider an OEM BMW key fob.
A Small Flathead Screwdriver: This will help you open the key fob casing.

Replacing the Battery: A Step-by-Step Guide

Locate the Release Button: On the back of your key fob, find the small, silver button.
Release the Key Blade: Press the release button and gently slide out the metal key blade from the fob.
Separate the Fob Halves: Use your flathead screwdriver to carefully pry open the key fob casing along the seam.
Remove and Replace the Battery: Gently remove the old CR2032 battery and insert the new one, making sure the positive (+) side is facing up.
Reassemble the Key Fob: Carefully snap the two halves of the key fob back together.
Reinsert the Key Blade: Slide the metal key blade back into its slot until it clicks securely.

Still Having Trouble?

If you’ve replaced the battery and your key fob is still acting up, there might be other issues at play. Here are a few things to consider:

Key Fob Programming: In some cases, you might need to reprogram your key fob after replacing the battery. Refer to your owner’s manual for instructions or consult a qualified technician.
Key Fob Damage: Physical damage to your key fob, like water exposure or impact, could be affecting its functionality.
Vehicle Issues: While less common, problems with your car’s receiver could also cause key fob communication issues.
