2. The SmartKey (Infrared Technology)
In 1997, Mercedes-Benz presented the "SmartKey." This was an advanced plastic fob that used infrared (IR) light to interact with the Drive Authorization System (DAS). Rather of a metal blade turning a cylinder, the SmartKey is placed into the Electronic Ignition Switch (EIS), which "questions" the key before permitting the engine to start.

Each Mercedes key is configured with a distinct "rolling code." Every time the key is used, the code changes based on an intricate algorithm shared between the key and the vehicle's onboard computer. This prevents "code grabbing" by thieves. Configuring this synchronization involves specialized software and hardware that needs substantial investment from the service company. Additionally, for the newest designs, the security data is continued a protected server in Germany, and the "handshake" between the car and the server must be validated through the dealer.

Inspect your policy to see if you are covered.Regularly Asked Questions (FAQ)1. Does a locksmith need to concern the car, or can I simply bring the VIN?

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