Mercedes-Benz Key Fobs

Is your key fob increasingly slow to respond? This is a sure sign that the batteries in the key fob for your Mercedes-Benz SUV or car should be replaced. Our team will happily assist with the battery replacement at Mercedes-Benz of Des Moines and with all of your other auto service needs.

Signs That a Battery Replacement Is Needed

When your key fob’s battery is losing power, you could notice several warning signs. For example, the buttons to unlock and lock the doors may not respond on the first attempt. If your vehicle is equipped with KEYLESS GO®, the engine may not start quickly by pushing the fob button. Another warning sign is the illumination of an indicator light on the dashboard. Specifically, this warning light will be for the vehicle’s charging system.

How to Replace the Fob Battery

You can become increasingly frustrated with the key fob as its battery loses power. To avoid frustration and other issues related to a dead fob battery now is the time to replace it. Research the type of battery required for your model’s fob, and connect with our parts department to place your order. If you have a Smart Key system, you will need to pull out the latch located at the end of the unit. Insert your key into the slot that you have now accessed. You can replace the old batteries with new ones. If you have a Chrome Key, you will need to remove the fob’s cover to replace the battery.
