What are the two styles of Mercedes-Benz keys?
2 Answers
All Mercedes-Benz cars have the same key. The two styles likely refer to the mechanical key and the remote key. Key classification: Car keys are divided into two types, one without an anti-theft chip and the other with an anti-theft chip. Keys with anti-theft chips are commonly found in some low-end models and don't even have a remote control, which is now rare. Smart key: A smart key is equivalent to a small radio wave transmitter. The chip inside the key contains a unique ID code that matches the car. When the smart key emits a radio wave, it is received by the car. After confirmation by the car's anti-theft system control unit, the key is recognized, and then the door can be opened and the engine started.
I've been driving Mercedes-Benz for years and noticed their keys mainly come in two styles. One is the traditional flip key, the kind with a hard plastic shell that can be snapped open to reveal the metal key head. It's quite intuitive for daily use—just insert it into the door or ignition slot, and it feels solid, not afraid of being dropped. However, it can feel a bit bulky when carrying more items in the pocket. The other type is the smart key, designed like a small card or with a streamlined shape, supporting keyless entry. You can automatically unlock the car from a few meters away and start the engine by pressing the ignition button once inside. It's incredibly convenient, especially when you're in a hurry and don’t need to fumble for the key. The smart key also integrates an anti-theft system, allowing remote locking of the car if it’s lost. Personally, I prefer the smart key because it makes life quicker. But the traditional key is simpler to maintain, with easier battery changes and such. When buying a car, considering the model's age can help decide which type to choose.
