Why Are Mercedes-Benz Keys So Expensive?
The primary factor for the high expense of Mercedes-Benz secrets depends on the brand's Drive Authorization System (DAS). Since the mid-1990s, Mercedes-Benz has utilized advanced anti-theft innovation that prevents the lorry from starting unless it receives a distinct, encrypted signal from the key.

Modern Mercedes "SmartKeys" utilize infrared (IR) and radio frequency (RF) signals. When the key is placed into the Electronic Ignition Switch (EIS) or brought near a Keyless-Go automobile, a "handshake" takes place. The car and the key exchange a rolling code that alters whenever the car is started. This level of security makes the vehicles exceptionally challenging to steal, but it also implies that a replacement key is a high-tech computer element rather than a basic mechanical tool.
