2. The SmartKey (Infrared Technology)
In 1997, Mercedes-Benz introduced the "SmartKey." This was a revolutionary plastic fob that used infrared (IR) light to communicate with the Drive Authorization System (DAS). Instead of a metal blade turning a cylinder, the SmartKey is placed into the Electronic Ignition Switch (EIS), which "questions" the key before allowing the engine to begin.
3. Keyless Go
The next leap was Keyless Go technology. This allows the driver to keep the key in their pocket or purse. The lorry discovers the presence of the key via a Radio Frequency (RF) signal, allowing the driver to open the doors by touching the handle and begin the engine with a push-button ignition.

Why Are Mercedes Keys So Expensive?

Each Mercedes key is configured with a special "rolling code." Every time the key is utilized, the code changes based on a complicated algorithm shared between the key and the lorry's onboard computer. This avoids "code grabbing" by burglars. Setting this synchronization involves specialized software application and hardware that needs considerable financial investment from the service company. Moreover, for the most recent models, the security information is continued a protected server in Germany, and the "handshake" between the car and the server must be confirmed through the dealership.

2. If I find my lost key later on, will it still work?
