1998–2014 Mercedes EIS EZS Ignition Switch Clone Programming Service Mercedes-Benz Electronic Ignition Switch (EIS / EZS) Cloning Service This is a mail-in EIS / EZS cloning and programming service for select Mercedes-Benz vehicles equipped with supported FBS3 Electronic Ignition Switch modules. We transfer the necessary vehicle-specific data from your original EIS into a compatible replacement EIS that you provide. Once completed, the replacement is prepared for installation into the original vehicle. YOU MUST SEND BOTH YOUR ORIGINAL EIS AND A COMPATIBLE REPLACEMENT EIS. A REPLACEMENT EIS IS NOT INCLUDED. WHAT IS THIS SERVICE FOR? This service allows a compatible used replacement EIS / EZS to be used in place of your original Electronic Ignition Switch. The necessary vehicle-specific data is transferred from your original EIS into the replacement so that it is prepared to operate with the original vehicle. This service is intended for situations where the original EIS needs to be replaced but still contains recoverable vehicle-specific data.

This service is for supported FBS3 EIS / EZS modules. FBS4 modules are not supported. Some Mercedes-Benz models transitioned to FBS4 before the 2015 model year, so compatibility cannot be determined by vehicle year alone.
