Replacing Your 2018 Mercedes GLA 250 Key Fob Battery: A Step-by-Step Guide
Replacing the key fob battery is a simple DIY task that can save you time and money. Here’s a step-by-step guide to get you started:
-
Gather Your Supplies: You’ll need a new CR2025 battery (easily found at most convenience stores and online), a small flat-head screwdriver, and your key fob.
-
Locate the Battery Compartment: Look for a small release button or notch on the back or side of your key fob. This will help you open the battery compartment.
-
Open the Compartment: Gently insert the flat-head screwdriver into the notch or press the release button while prying open the compartment.
-
Remove the Old Battery: Carefully remove the old battery, noting the orientation (positive (+) side facing up).

Insert the New Battery: Place the new CR2025 battery into the compartment, ensuring it matches the same orientation as the old battery.

Close the Compartment: Snap the battery compartment back together, making sure it’s securely closed.
-
Test the Key Fob: Try locking and unlocking your car doors, and starting the engine to confirm the new battery is working correctly.
Pro Tip from John Miller, Automotive Electrician: “Always handle the new battery by its edges to avoid transferring oils from your skin, which can reduce its lifespan.”
