Modern vehicle security architectures (such as GM Global-B and high-encryption push-to-start CAN systems) make traditional wire-interrupt bypasses or firmware-based Key2Go routines difficult or impossible without triggering OEM immobilizer lockouts.
The BP1 Module solves this by acting as a true authorized factory smart key during remote start attempts, eliminating the need to sacrifice a physical factory key inside a key-wrap box (like the legacy 556UXL). The DKPROG is the hardware tool required by installers to extract, synthesize, and write OEM transponder payload data onto the BP1 module via DirectLinkDT or DirectLoader mobile/PC applications.

Key Technical Features & Workflow
-
True Authorized Start: Unlike standard firmware bypasses that “trick” immobilizer lines, the DKPROG writes actual authorized key logic to the BP1, which presents genuine RFID/smart-key data to the vehicle upon activation.
-
Zero IMMO Wires Intercepted: Eliminates the risk of cutting high-frequency smart key antenna lines or interrupting sensitive CAN-bus immobilizer circuits.
-
Advanced OEM Platform Support: Designed specifically to overcome complex encryption barriers, including 2021+ GM Global-B architectures and push-to-start proximity systems.
-
D2D Plug-and-Play Integration: The programmed BP1 module interfaces directly with DS3, DS3+, DS4, and DS4+ digital brains via a standard 4-pin D2D harness cable without auxiliary relay wiring.
-
DirectLoader / DirectLinkDT Integration: Syncs wirelessly via Bluetooth with DirectLoader mobile apps or connected PCs to download vehicle-specific key profiles from Directed cloud servers.
