The security architecture includes several interconnected components:

• EIS (Electronic Ignition Switch): The “brain” that authenticates the key.

The Specialized Locksmith Route

Not all locksmiths can handle a Mercedes. A specialized vehicle locksmith needs to have sophisticated software (like VVDI or Abrites) to draw out data from the car’s EIS and compose it onto a new chip. This is a highly technical procedure. For newer models (post-2014/ 2015), lots of locksmiths are locked out due to Mercedes-Benz’s upgraded “FBS4” security protocol, leaving the dealer as the only option for those years.
