Owning a luxurious 2018 Mercedes GLC 300 comes with the perk of keyless entry and ignition. But what happens when your key fob starts acting up due to a low battery? A dead key fob battery can be a major inconvenience, leaving you stranded. This comprehensive guide will walk you through the simple steps of changing a 2018 Mercedes GLC 300 key fob battery, empowering you to take charge and get back on the road in no time.
Identifying a Dying Key Fob Battery
Before you start digging for tools, it’s crucial to confirm that your key fob battery is the culprit. Here are a few telltale signs:
- Decreased Range: You find yourself standing closer to your GLC 300 than usual to lock or unlock the doors.
- Intermittent Functionality: The key fob works sporadically, requiring multiple attempts.
- Warning Messages: Your dashboard might display warnings like “Key Fob Battery Low.”
If you notice any of these signs, it’s time for a battery swap.
What You’ll Need for the Battery Change
Fortunately, changing the key fob battery is a straightforward process. Here’s what you need:
- A new CR2032 battery (easily found at most stores)
- A small flat-head screwdriver
Step-by-Step Guide to Replacing the Battery
Follow these simple steps to replace your 2018 Mercedes GLC 300 key fob battery:
-
Locate the Emergency Key Slot: On the back of your key fob, you’ll find a small, rectangular slot.
-
Release the Emergency Key: Insert the flat-head screwdriver into the slot and gently pry open the key fob casing. Be careful not to use excessive force.
-
Separate the Halves: Once the casing is slightly open, you can carefully separate the two halves of the key fob to access the battery compartment.
-
Remove the Old Battery: Gently pry out the old CR2032 battery from its slot. Note the orientation of the battery for correct replacement.
-
Install the New Battery: Insert the new CR2032 battery into the slot, ensuring the positive (+) side faces upwards, just like the old battery.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob and press them together until you hear a click, indicating they are securely closed.
-
Test the Key Fob: Try locking and unlocking your GLC 300 to ensure the new battery is working correctly.
