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.

But don’t worry – at Y Tech, we specialize in helping our customers with any immobilizer-related issue on their Mercedes Benz vehicles. Our expert technicians are well-versed in both DAS3 (FBS3) and DAS4 (FBS4) systems and can quickly diagnose and repair any issue you may be experiencing.
