| PLEASE NOTE | FBS3 is Mercedes-Benz's infrared (IR) immobilizer and start system used on vehicles manufactured until approximately 2014-2015. Unlike traditional transponders, it uses "chrome" or "fish" type smart keys and requires specialized programming tools to add keys or replace modules. This security system includes key modules such as the electronic ignition switch (EIS), engine computer (ECM), and steering column lock module (ELV). If any of these parts fail or the key is lost, automotive locksmiths or specialized technicians use advanced diagnostic equipment (such as Autel, CGDI MB or the OBDSTAR KeyMaster G3 kit) to read PIN codes and virginize or reprogram the components. |
