Having trouble with your 2015 Mercedes-Benz GLK350 key fob? It might be time for a new battery. Key fobs these days are pretty sophisticated, and that means they need a good battery to keep working smoothly. If your key fob’s acting up, a dead battery is often the culprit.
Here’s the thing about key fob batteries, they don’t last forever. Over time, they lose their charge, just like any other battery. And when that happens, you might find your key fob isn’t quite as responsive as it used to be. Maybe you have to press the buttons multiple times to get it to work, or perhaps the range is starting to dwindle.
Don’t worry, though. Replacing the key fob battery in your 2015 Mercedes-Benz GLK350 is a fairly straightforward process, even for someone who’s not exactly a car expert. In this article, we’ll walk you through everything you need to know, from identifying the right battery to replacing it yourself.
Signs You Need a New Key Fob Battery for Your 2015 GLK350
Before we jump into the how-to, let’s make sure you actually need a new key fob battery. Here are some common signs:
- Decreased Range: You’re noticing you have to be much closer to your GLK350 for the key fob to work.
- Intermittent Functioning: The lock, unlock, or panic buttons sometimes work and sometimes don’t, requiring multiple presses.
- No Response: The key fob doesn’t seem to be sending any signals at all.
- Dashboard Warning: Some GLK350 models may display a “Key Fob Battery Low” warning on the dashboard.
What Type of Battery Does a 2015 Mercedes-Benz GLK350 Key Fob Use?
The 2015 GLK350 key fob uses a CR2045 battery. This is a common type of 3-volt lithium coin battery that you can find at most auto parts stores, electronics stores, and even some larger retailers.
How to Change the Key Fob Battery in a 2015 Mercedes-Benz GLK350
Replacing the battery in your GLK350 key fob is easier than you might think. Here’s a step-by-step guide:
What You’ll Need:
- A new CR2045 battery
- A small flat-head screwdriver or a key (Some key fobs have a small slot for easy opening).
Instructions:
-
Locate the Battery Compartment: On the back of your GLK350 key fob, you’ll find a small notch or indentation. This indicates the location of the battery compartment.
-
Open the Battery Compartment: Insert your flat-head screwdriver (or key, if applicable) into the notch and gently pry open the compartment. You should hear a slight click when it releases.
-
Remove the Old Battery: Carefully remove the old CR2045 battery. Note which side was facing up, as the new battery will need to be installed the same way.
-
Insert the New Battery: Place the new CR2045 battery into the compartment, ensuring the positive (+) side is facing the same direction as the old battery.
-
Close the Compartment: Align the two halves of the key fob and press them together firmly until you hear a click, indicating it’s securely closed.
-
Test the Key Fob: Try locking and unlocking your GLK350 to make sure the new battery is working properly.

Handle with Care: When handling the battery and key fob components, be gentle to avoid damaging any of the internal electronics.
