Mercedes - Benz FBS3 and FBS4 Immobilizer Systems

If you own a Mercedes Benz vehicle from 1998, you may already know that it uses an electronic key fob and electronic ignition switch as its primary immobilization device, with an electronic steering lock or shifter mechanism serving as a secondary immobilization device. Unfortunately, it is not uncommon for the EIS, ESL, key fobs, and shifter units (ESMs) to fail, and even more frustratingly, they are often misdiagnosed.
