2. The SmartKey (FBS2 and FBS3)
Introduced in 1997, the SmartKey changed the metal blade with an infrared remote. These secrets do not have a physical "cut" to start the engine. Instead, they communicate with the Electronic Ignition Switch (EIS) through infrared light and radio frequency.
3. Keyless Go

4. The Digital Key (FBS4)
The latest generation of Mercedes security (FBS4) is highly encrypted. These keys are connected to the vehicle's VIN at a hardware level, making third-party duplication substantially harder than earlier designs.

If the key starts the car however will not open the doors, the battery is most likely the perpetrator.Approximating the Cost of Replacement
