Owning a luxury SUV like the 2016 Mercedes GLE 350 is a dream, until that dreaded moment when your key fob stops working. Before you panic and envision a hefty dealership bill, the problem could be as simple as a dead key fob battery. Replacing it yourself is a quick and easy process, saving you time and money. This guide will walk you through everything you need to know about 2016 Mercedes Gle 350 Key Fob Battery Replacement.
Recognizing a Dying Key Fob Battery
Several telltale signs indicate your Mercedes GLE 350 key fob battery is nearing its end. If you’ve noticed any of the following, it’s time to consider a replacement:
- Decreased Range: Are you finding yourself standing closer and closer to your car to get it to unlock? This reduced signal strength is a classic sign of a fading battery.
- Delayed Response: A lag between pressing the button and your car responding is another signal. The key fob might take several pushes to register.
- Intermittent Functioning: Does your key fob work perfectly sometimes and then act completely dead other times? This inconsistency is a strong indicator of a dying battery.
- Warning Messages: Your dashboard might display messages like “Key Fob Battery Low” – a clear call to action for a replacement.
What You’ll Need for the Replacement
Replacing your 2016 Mercedes GLE 350 key fob battery is straightforward and requires minimal tools:
- New Battery: You’ll need a CR2025 battery. These are readily available at most grocery stores, pharmacies, and online retailers.
- Small Flathead Screwdriver: This will be used to open the key fob casing. A small coin or a similar tool can also work in a pinch.
