Owning a Mercedes GLA 250 is a statement. It’s a statement of style, class, and performance. But even the most sophisticated machines need a little TLC from time to time, and your key fob is no exception. If your Mercedes GLA 250 key fob is acting up – think sluggish response or dim lights – it might be time for a new battery. Don’t worry, it’s a common issue, and we’re here to guide you through it.
Spotting a Dying Key Fob Battery: Is it Time for a Change?
Just like your car battery, your key fob battery won’t last forever. Here are some telltale signs that it’s nearing its end:
- Decreased Range: You find yourself standing closer and closer to your car to get it to lock or unlock.
- Intermittent Functioning: The key fob works sometimes, but not others, leaving you stranded at the most inconvenient moments.
- Warning Messages: Your dashboard might display a “Key Fob Battery Low” message, a clear sign it’s time to take action.
- Dim Indicator Lights: The LED lights on your key fob, if it has them, will appear dimmer than usual.
Choosing the Right Battery: Don’t Get Lost in the Aisle
You wouldn’t put just any fuel in your Mercedes, would you? The same goes for your key fob battery. Most Mercedes GLA 250 key fobs use a CR2025 or CR2032 battery. These are readily available online or at your local auto parts store. To be absolutely sure, consult your owner’s manual or look for markings on the old battery.
DIY Battery Replacement: A Simple Guide
Replacing your Mercedes Gla 250 Key Fob Battery is a breeze, and you don’t need to be a mechanic to do it. Here’s a step-by-step guide:
- Locate the Release Button: Look for a small button or switch on your key fob. This will usually be on the back or side.
- Release the Key Blade: Press the release button and gently slide out the metal key blade.

- Replace the Battery: Remove the old battery and insert the new one, making sure to match the + and – terminals.
- Reassemble the Key Fob: Snap the casing back together and reinsert the key blade.
And voila! You’ve successfully replaced your key fob battery. Test it out to make sure everything’s working smoothly.
Expert Tip from John Miller, ASE Certified Master Technician: “When handling the key fob battery, avoid touching the flat surfaces. This can affect the battery’s lifespan.”
Beyond the Battery: Other Key Fob Issues
Sometimes, a new battery isn’t the solution. If you’re still experiencing problems, there might be other culprits:
- Key Fob Programming: Your key fob might need to be reprogrammed to your car. You can usually do this yourself by following the instructions in your owner’s manual, or you can visit a dealership.
- Antenna Issues: The antenna in your car that receives the signal from your key fob might be faulty. This would require professional diagnosis and repair.
Expert Tip from John Miller, ASE Certified Master Technician: “If you’re experiencing intermittent key fob issues, try holding the fob close to the steering column while pressing the buttons. This can sometimes improve signal strength.”
