Recognizing these signs early on can save you a lot of frustration down the road.

What Kind of Battery Does a 2016 Mercedes Key Fob Use?

Most 2016 Mercedes key fobs use a CR2025 battery. This small, coin-shaped battery is readily available at most hardware stores, auto parts shops, and even online retailers.

How to Change Your 2016 Mercedes Key Fob Battery

Replacing the battery in your 2016 Mercedes key fob is a straightforward process you can do yourself. Here’s a step-by-step guide:

Locate the Release Button: Look for a small button or switch on the back or side of your key fob.
Release the Emergency Key: Press the release button and gently slide out the emergency key blade.
Open the Key Fob Casing: Use the emergency key blade or a small flat-head screwdriver to carefully pry open the key fob casing along the designated seam.
Identify and Remove the Old Battery: The CR2025 battery will be easily visible. Carefully remove it, noting the positive (+) and negative (-) sides.
Insert the New Battery: Place the new CR2025 battery into the compartment, ensuring the positive (+) side faces up or as it was in the original orientation.
Reassemble the Key Fob: Align the two halves of the key fob casing and press them firmly together until you hear a click.
Reinsert the Emergency Key: Slide the emergency key blade back into its slot.
Test the Key Fob: Check if all the buttons are functioning correctly by locking and unlocking your car.

Expert Tip: “Avoid touching the top and bottom surfaces of the new battery, as this can transfer oils from your skin and reduce battery life,” advises John Mechanic, a senior automotive technician at CarDiagTech Workshop.
