- Decreased Range: You find yourself having to stand closer to your car for the key fob to unlock the doors or activate the trunk.
- Intermittent Functioning: The key fob only works sporadically, forcing you to press the buttons multiple times.
- Warning Messages: Your dashboard displays warnings about low key fob battery or similar messages.
- No Response: The key fob becomes completely unresponsive, leaving you unable to lock, unlock, or start your vehicle.
Replacing Your 2019 Mercedes GLA 250 Key Fob Battery: A Step-by-Step Guide
Don’t fret if you’re experiencing any of these issues! Replacing the battery in your 2019 Mercedes GLA 250 key fob is straightforward. Here’s a step-by-step guide:
What you’ll need:
- A new CR2025 battery (widely available at auto parts stores, supermarkets, and online retailers)
- A small flat-head screwdriver or a plastic pry tool
Instructions:
- Locate the Battery Compartment: Turn your key fob over and identify the small release button or notch on the back.
- Open the Key Fob: Gently press the release button or insert the flat-head screwdriver into the notch and carefully pry open the key fob. Be careful not to use excessive force.
- Remove the Old Battery: Identify the old CR2025 battery. Carefully pry it out using your fingernail or the tip of the screwdriver. Note the battery’s orientation for correct placement of the new battery.
- Insert the New Battery: Place the new CR2025 battery into the compartment, ensuring it matches the same orientation as the old battery (positive (+) side facing up).
- Reassemble the Key Fob: Align the two halves of the key fob and press them together firmly until you hear a click, indicating it’s securely closed.
- Test the Key Fob: Try locking and unlocking your car doors and using other key fob functions to ensure the new battery is working correctly.
Pro Tip: Avoid touching the top and bottom surfaces of the new battery, as this can transfer oils from your skin and potentially shorten its lifespan.
Beyond the Battery: Additional Key Fob Troubleshooting Tips
While a dead battery is the most common issue, if replacing it doesn’t solve the problem, here are a few additional troubleshooting tips:
