Having trouble with your 2014 Mercedes GL450 key fob? A dead battery is often the culprit. Don’t worry, replacing it is a quick and straightforward process you can handle yourself. This guide will walk you through everything you need to know about replacing your 2014 Mercedes GL450 key fob battery, from identifying the right replacement to getting your key fob back in action.
What You’ll Need to Replace Your Key Fob Battery
Before you start, gather these simple tools:
- A new CR2025 battery: This is the standard battery for most Mercedes key fobs, including the 2014 GL450.
- A small flat-head screwdriver: You’ll need this to open the key fob casing.
- A plastic pry tool (optional): This can help prevent scratching your key fob when prying it open, but a flat-head screwdriver will also work.
How to Replace Your 2014 Mercedes GL450 Key Fob Battery: A Step-by-Step Guide
Follow these simple steps to replace your key fob battery:
- Locate the release button on the back of your key fob. It’s a small, usually silver button.
- Press the release button and gently slide out the metal key. This will expose a small slot on the side of the key fob.
- Insert the flat-head screwdriver (or plastic pry tool) into the slot and gently pry open the key fob casing. Be careful not to use excessive force, as this could damage the casing.
- Locate the old battery. It will be sitting in a compartment, usually secured by a small clip.
- Carefully remove the old battery and note its orientation. The positive (+) and negative (-) sides should be clearly marked.
- Insert the new CR2025 battery into the compartment, making sure it matches the orientation of the old battery.
- Snap the key fob casing back together. You should hear a click when it’s properly secured.
- Reinsert the metal key and test your key fob. It should now be working perfectly.
Still Having Trouble?
If your key fob still isn’t working after replacing the battery, there could be another issue, such as:
- Faulty key fob programming: You might need to reprogram your key fob to your car.
- Damaged key fob: A physical impact or water damage could require a key fob replacement.
“It’s important to remember that while replacing the battery yourself is usually a simple task, more complex issues might require a visit to your local Mercedes dealership or a qualified automotive locksmith,” advises John Miller, a senior technician at Car Diagtech Workshop.
