Dongfeng GX Ignition lock and door lock cylinder with key assembly 6105915-C6104

Engineered for frequent use (typical commercial vehicles require 500+ lock/unlock cycles monthly), the 6105915-C6104 assembly uses wear-resistant materials to extend service life. The lock cylinder pins are chrome-plated (plating thickness 5μm) to reduce friction, while the cylinder inner wall is polished to a smooth finish (Ra ≤ 0.2μm)—minimizing wear from key insertion/removal. The keys are crafted from nickel-silver alloy (NiCuZn20) with a scratch-resistant PVD coating, preventing bending or tooth deformation even after 100,000+ cycles. Testing shows the assembly maintains smooth operation with no increase in key turning force (remains at 5-8N) after 50,000 cycles, and the lock cylinders resist corrosion from sweat, rain, or road salt—ensuring reliable performance for over 7 years

A key advantage of the 6105915-C6104 assembly is its integrated key design: one set of keys (2 master keys included) operates both the ignition lock and all door lock cylinders (driver, passenger, and cargo doors, where applicable). The keys feature a ergonomic plastic grip (TPR material, shore hardness 60±5A) for comfortable handling, even in cold weather, and include a key ring loop for easy storage with other tools. Each key is laser-engraved with a unique serial number, allowing for precise key duplication (only via authorized Dongfeng service centers) to prevent unauthorized key copying. The key-to-lock fit is calibrated to ±0.02mm, ensuring smooth insertion and turning without jamming—critical for drivers who need quick access to the vehicle during busy logistics operations

Exclusively tailored for Dongfeng GX commercial vehicles (including heavy-duty trucks, cargo models, and long-haul variants), the 6105915-C6104 assembly strictly adheres to original equipment (OE) specifications. Manufactured using CNC machining and precision casting, the ignition lock housing and door lock cylinders achieve dimensional accuracy within ±0.1mm—perfectly matching the Dongfeng GX’s steering column (ignition lock) and door panel (lock cylinders) mounting holes. The ignition lock features a standardized 12-pin electrical connector that directly plugs into the vehicle’s wiring harness, eliminating the need for wire modification. It is fully compatible with all Dongfeng GX models produced since 2022, including those with manual or automated transmission systems, making it a direct replacement part for factory assembly or after-sales repairs

The 6105915-C6104 assembly is designed for hassle-free installation and minimal upkeep. It comes with a complete hardware kit, including mounting screws (M5×10mm), lock washers, and a installation template for door lock cylinders—guiding precise positioning. The ignition lock can be installed in the steering column via 3 pre-drilled holes, while door lock cylinders fit into existing door panel cutouts (no drilling required). Installation can be completed by two technicians in 30-40 minutes (35% faster than non-OE lock assemblies). For maintenance, the lock cylinders can be lubricated with dry graphite powder (included in the kit) every 12 months to maintain smooth operation, and the keys’ PVD coating resists stains—requiring only occasional wiping with a damp cloth. The assembly also includes a 24-month warranty against material defects (e.g., key breakage, lock jamming) and manufacturing errors
