How to Start a Mercedes When the Key Fob Battery is Dead?
2 Answers
If your Mercedes key fob runs out of battery, you can try starting the vehicle by pressing it firmly against the induction area to utilize any remaining power. If this doesn't work, you'll need to either use the mechanical key to start the vehicle or replace the battery first. Mercedes vehicles typically have two locations for the keyhole: one is beneath the one-touch start button on the steering wheel—you'll need to remove the cover of the one-touch start button and insert the key, then turn it 90 degrees to start the car. The other location is inside the center armrest compartment, which is relatively deep; you can also use the mechanical key to start the vehicle directly. The Mercedes GLC is the first all-new crossover model launched by Mercedes, with body dimensions of 4764mm in length, 1898mm in width, and 1642mm in height, and a wheelbase of 2973mm.
I've seen many car owners ask about this. Starting a Mercedes when the key fob is dead is actually quite simple. If you notice the key isn't responding, don't panic. First, bring the key close to the start button or the induction area below the steering column. Mercedes designed this backup method: there's a coil there that can wirelessly charge and read the chip information in the key to start the engine. I remember the manual mentioned that after placing the key properly, holding the start button for a few seconds should start the car. If placing it close doesn't work, try putting the key near the center console or check if the battery is completely dead; sometimes a slight charge might still work. For prevention, it's good practice to replace the coin battery (CR2025 type, available at supermarkets) every 1-2 years. I've shared this in the community, and most people succeeded. The key is not to rush—your car is a reliable partner, and if starting fails, calling for help isn't too late. Safety first: ensure the car is securely parked when attempting this.
