Kinds Of Mercedes Keys Explained
1. Conventional Blade Keys

The car identifies the key's proximity, enabling the doors to be unlocked by touching the deal with and the engine to be started through a button.

The Process: The dealership orders the key based on your VIN. It arrives "pre-cut" from Germany. You then bring the car in for a service technician to sync the key to the car's computer system.
