Description
BENZ FBS3 KIT
Turn your OBDSTAR G3 into a dedicated Mercedes-Benz service platform
Key Programming · PIN reading · All Keys Lost · EIS/ELV/ISM/ECU/TCM module service
- ✓ Online PIN calculation – fast and simple
- ✓ AKL support, most models directly via OBD
- ✓ Far beyond key Programming: electronic module service
Three Core Capabilities
PIN Reading
Calculate the PIN via a working key or in AKL mode, and read PIN from a BE key. The calculation is online and usually takes 5-10 minutes.
Module Service (Virgin)
Reset/renew and match EIS/EZS, engine ECU (ECM), transmission (TCM), ISM module and electronic steering lock (ELV) — where supported.
Key Programming
Read key data, generate key file, erase BE key and write BE key — for add-key and All Keys Lost scenarios.
What is the BENZ FBS3 KIT?
The BENZ FBS3 KIT is a dedicated OBDSTAR accessory kit that transforms the X300 Classic G3 into a dedicated Mercedes-Benz Programming and service platform for supported FBS3 systems. Rather than investing in a separate Mercedes-only programmer, a locksmith who already owns a G3 can expand into advanced Mercedes immobilizer and module work — using the same device and the same interface.
Unlike tools that only do key Programming, the FBS3 KIT also handles EIS replacement and matching a faulty EIS to the vehicle — a critical capability in All Keys Lost (AKL) jobs and on cars with a damaged ignition module.
What's in the kit?
Dedicated cable for vehicle data collection
Adapter board
Dedicated connection cable
Who is this kit for?
- Automotive locksmiths expanding into Mercedes-Benz services
- Existing OBDSTAR G3 owners adding dedicated Mercedes capability
- Workshops looking to complement existing tools (Xhorse, Autel and others) with another Mercedes solution
- Technicians performing EIS, ELV, ISM, ECU and transmission service alongside key Programming
Much More Than Key Programming
One of the kit's greatest strengths is that it is designed for far more than adding keys. While most Mercedes solutions on the market focus mainly on the immobilizer, OBDSTAR has steadily expanded into electronic module service too — making the G3 a Mercedes electronic service platform, not just a key programmer.
Complements Your Existing Toolbox
The kit is not necessarily meant to replace every other Mercedes tool — but to complement your workshop:
- Owners of the Xhorse Key Tool MIDI + Multi-Prog gain advanced Mercedes capabilities without buying the separate VVDI MB platform
- Workshops using Autel add another dedicated Mercedes solution with different workflows and module functions
- Existing OBDSTAR users keep working in a familiar interface instead of maintaining multiple software ecosystems
Convenience Advantage: Android, No PC
Unlike PC-based Mercedes programmers, the OBDSTAR solution runs directly from the Android-based G3 tablet. For mobile locksmiths, that means:
- Fewer devices to carry
- No Windows laptop required for supported procedures
- Integrated software updates
- One interface across multiple vehicle brands
