Owning a luxury SUV like the 2015 Mercedes ML350 is a dream, until that dreaded moment your key fob stops working. Before you panic and envision a hefty dealership bill, a dead key fob battery is often the culprit and easily fixed. Let’s dive into everything you need to know about your 2015 Mercedes Ml350 Key Fob Battery.
Common Signs Your Key Fob Battery is Dying
Just like your car battery, your key fob battery doesn’t last forever. Here are some telltale signs that it’s time for a replacement:
- Decreased Range: Is your car only responding to the key fob at very close range? This is a classic sign your battery is losing power.
- Intermittent Functionality: If your car locks and unlocks intermittently or the alarm acts up, a weak key fob battery could be to blame.
- Dashboard Warning: Some Mercedes models will display a “Key Fob Battery Low” warning on the dashboard.
- Physical Damage: Inspect your key fob for any physical cracks or leaks. Damage to the casing can expose the battery to the elements and shorten its lifespan.

Don’t worry, changing your key fob battery is a quick and easy process, even for those who aren’t DIY inclined. Here’s a step-by-step guide:
-
Locate the Emergency Key Slot: On the side of your key fob, you’ll find a small slot. This is the emergency key slot.
-
Release the Emergency Key: Insert the emergency key (or a small flat-head screwdriver) into the slot and gently pry open the key fob casing.
-
Identify the Battery: Inside the key fob, you’ll see the CR2032 battery. Carefully remove it by gently prying it out.

Tips for Extending Your Key Fob Battery Life
While key fob batteries have a limited lifespan, here are a few tips to help them last a little longer:
- Avoid Frequent Button Pressing: Only press the buttons when necessary. Excessive pressing, even within range, can drain the battery faster.

- Store it Properly: When not in use, store your key fob in a cool, dry place.
