Dongfeng GX Ignition lock assembly with key assembly 3704010-C6101-HJ

The part number 3704010-C6101-HJ is a unique official identifier authorized by Dongfeng, distinguishing this genuine ignition lock (with key) from counterfeit alternatives. Inputting this number into Dongfeng’s official parts database provides details: production batch, key blank code (matching the GX’s original key design), and quality inspection records. Critically, the assembly includes 2 factory-programmed keys that are pre-matched to the lock’s internal tumblers—no additional key cutting or programming is needed, unlike aftermarket locks that require third-party key pairing. The keys feature the Dongfeng brand logo and durable plastic heads (resisting breakage). The part number is etched on the lock’s housing, remaining legible for authenticity checks, ensuring the ignition system retains its original anti-theft security

As a core anti-theft component, this ignition lock assembly integrates dual security features to protect the Dongfeng GX. First, the mechanical tumbler system uses precision-machined pins (5-6 pin configuration) that only align with the matched original keys, preventing unauthorized key access. Second, it includes an electronic immobilizer chip (where applicable, matching the GX’s on-board anti-theft system) that communicates with the vehicle’s ECU—only recognizing the key’s unique chip signal to allow engine start, blocking hot-wiring attempts. The lock also has a steering lock function: inserting/removing the key engages/disengages the steering column lock, preventing vehicle theft when parked. Tested against common theft tools (e.g., lock picks, drill bits), the assembly resists forced entry, meeting Dongfeng’s anti-theft safety standards

To withstand frequent use and harsh environments, the ignition lock uses high-quality materials for both mechanical and electrical components. The lock body is made of zinc alloy (high tensile strength ≥200MPa) with a chrome-plated surface, resisting corrosion from moisture and road salt. Internal tumblers are made of hardened steel (HRC 45-50), reducing wear from key insertion/removal (tested for 10,000+ cycles with no failure). Electrical contacts are silver-plated copper (low resistance ≤30mΩ), ensuring stable current transmission for ignition, accessory power, and starter activation—avoiding intermittent no-start issues. The wiring connector is made of flame-retardant ABS plastic (meeting UL94 V-0 standard), preventing electrical short circuits. Every unit undergoes 100% testing: mechanical wear tests, electrical continuity checks, and corrosion resistance tests, guaranteeing a service life of 8-10 years

Designed for efficient replacement, this ignition lock assembly features user-friendly installation that requires basic tools (Phillips screwdriver, 8mm socket wrench). It follows the Dongfeng GX’s original mounting design: remove the steering column cover, disconnect the old lock’s wiring harness, unbolt the old lock (2-3 mounting screws), and install the new lock by reversing the steps. No steering column disassembly or electrical rewiring is needed, as the wiring harness connector is plug-and-play. The assembly includes alignment marks (e.g., “ON” position indicator) to ensure correct orientation, and a bilingual (English/Chinese) manual provides step-by-step instructions—including safety tips (e.g., disconnecting the battery before installation). Even novice maintenance personnel can complete replacement in 40-50 minutes, ensuring the ignition system operates as reliably as the original
