Owning a 2016 Mercedes Benz E350 is a statement. It speaks of luxury, performance, and sophistication. But even the most prestigious vehicles require routine maintenance, and your key fob is no exception. A dead key fob battery can leave you stranded, so knowing how to identify, replace, and care for your 2016 Mercedes Benz E350 key fob battery is essential.
Signs Your Mercedes Key Fob Battery Needs Replacing
Several telltale signs indicate your Mercedes key fob battery needs replacing. Recognizing these signs early can save you time, frustration, and potentially an emergency call to roadside assistance.
- Decreased Signal Range: Is your car only responding to your key fob at very close range? This diminished signal strength is often the first sign of a weakening battery.
- Inconsistent Locking/Unlocking: Do you find yourself repeatedly pressing the lock or unlock button on your key fob before the car responds? This inconsistent behavior can signal a dying battery.
- Dashboard Warning Light: Some Mercedes models will display a warning light on the dashboard when the key fob battery is low. Consult your owner’s manual to identify this specific warning light for your E350 model.
What Battery Does My 2016 Mercedes Benz E350 Key Fob Use?
Your 2016 Mercedes Benz E350 key fob requires a CR2025 battery, a common type of lithium coin battery readily available online, in auto parts stores, and even many supermarkets.
Replacing Your 2016 Mercedes Benz E350 Key Fob Battery: A Step-by-Step Guide
Replacing the battery in your key fob is a simple process that can be done at home with minimal tools. Here’s how to do it:
- Locate the Battery Compartment: Most 2016 E350 key fobs have a small release button or slider on the back. Press this button and gently separate the key fob’s two halves.
- Identify and Remove the Old Battery: The CR2025 battery will be easily visible. Carefully remove it by prying it out with a small flathead screwdriver or your fingernail. Avoid using excessive force to prevent damaging the battery or the key fob.
- Install the New Battery: Insert the new CR2025 battery, ensuring the positive (+) side faces upwards. This information is typically marked on the battery itself and within the battery compartment.
- Reassemble the Key Fob: 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: Ensure all buttons (lock, unlock, trunk release, panic) are functioning correctly.
Prolonging the Life of Your Mercedes Key Fob Battery
You can take several simple measures to maximize your key fob battery’s lifespan and avoid the inconvenience of a dead battery:
- Minimize Button Presses: While it might be tempting to repeatedly click the lock button to confirm your car is secured, excessive button pressing can drain the battery faster.
- Store Your Key Fob Properly: Extreme temperatures (both hot and cold) can impact battery life. Avoid storing your key fob in direct sunlight or extremely cold environments.
- Replace the Battery Proactively: Most key fob batteries last between 3-5 years. Consider replacing your battery proactively before it completely dies to prevent any unexpected issues.
