Product Info

Specifications

The Lonsdor SGW 12+8 Special Adapter is designed to bypass the Secure Gateway Module (SGW) on select Chrysler, Dodge, Jeep, and Fiat vehicles. It allows direct communication between diagnostic tools (like the Lonsdor K518 series) and the vehicle’s onboard systems—enabling functions such as key programming, diagnostics, and module coding that are otherwise restricted.

Vehicle Brands Supported:

  • Chrysler
  • Dodge
  • Jeep
  • Ram
  • Fiat
  • Alfa Romeo (select models with SGW)

Basic Functions

  • Supports most 2018–2020+ FCA models Compatible with 2018+ across all FCA brands—but not compatible with 2021+ models where SGW functionality is integrated into the BCM
  • Cross-platform compatibility Works with a wide range of aftermarket tools, not limited to Lonsdor devices
  • Time-saving and non-destructive setup Connects quickly to the SGW module, usually located behind the dash or glovebox, enabling faster diagnostics and key programming without interfering with vehicle wiring
  • Plug‑and‑play 12+8 harness compatibility Designed for the standard 12+8 connector layout used in FCA (Chrysler, Dodge, Jeep, RAM, Fiat, Alfa Romeo, Lancia, Maserati) vehicles since 2018
  • Bypasses Security Gateway (SGW) on 2018+ Chrysler-family vehicles Facilitates communication with key programming and diagnostic tools (e.g., Lonsdor, Launch, Autel, Xhorse, OBDSTAR) by bypassing the factory SGW module in the 12+8 wiring harness—no need to remove or splice existing components
