Dongfeng KL truck parts Right Outer Door Handle Assembly with Key Set 6105121-C3100-HJ

Designed as an all-in-one solution for door access and security, the assembly integrates a factory-matched lock cylinder and two brass keys (included in the set). The lock cylinder uses a 6-pin tumbler design (matching Dongfeng KL’s original key coding system) that resists picking and unauthorized access, providing reliable anti-theft protection. The keys are crafted from high-strength brass with a nickel-plated finish, which resists bending and corrosion—ensuring long-term usability even with frequent use. Unlike separate handle and lock purchases that require key rekeying, this integrated set arrives pre-matched to the lock cylinder, allowing immediate use after installation. The lock cylinder also features a dust cover that closes automatically when the key is removed, preventing dust, rainwater, or road salt from entering the cylinder and causing jamming

Built to withstand the harsh conditions of truck operation—including road debris impact, temperature fluctuations, and repeated use—the handle assembly uses rugged materials. The handle body is made of glass-fiber-reinforced ABS plastic (20% GF content) with a tensile strength of 45 MPa, which resists cracking from minor impacts (e.g., hitting branches or tools) and maintains rigidity in temperatures ranging from -40°C to 85°C. The internal linkage components (e.g., pivot pins, springs) are crafted from stainless steel (304 grade) that resists rust and wear, ensuring smooth handle operation through 100,000+ opening cycles. The handle’s outer surface is coated with a scratch-resistant acrylic layer (50μm thickness) that prevents unsightly marks from dirt or (fingernails), maintaining a clean appearance for years. Unlike low-grade plastic handles that break easily, this design ensures long-term reliability in tough trucking environments

Engineered to prioritize user comfort and ease of use, the handle features an ergonomic shape and optimized leverage. The handle’s grip area is curved to fit the natural contour of a hand, reducing hand fatigue during repeated use (e.g., frequent stops for deliveries or inspections). It requires a pulling force of only 8–10 N to open the door—significantly less than generic handles that demand 15+ N—making it easy to operate even with gloves (common in cold weather or construction sites). The lock cylinder is positioned at a 30° angle to the handle, allowing for natural key insertion without wrist twisting, and the key turns smoothly with minimal force. Unlike awkwardly shaped handles that cause discomfort, this ergonomic design enhances usability for all drivers, regardless of hand size or strength

Engineered to resist the elements and prevent corrosion, the assembly includes comprehensive weatherproofing features. The junction between the handle and door panel is sealed with an EPDM rubber gasket (8mm thickness) that blocks rainwater, snow, and road salt from seeping into the door interior—preventing damage to internal lock components or electrical systems (if equipped). The lock cylinder is filled with a waterproof lubricant that maintains smooth key operation even in heavy rain or freezing conditions, avoiding jamming caused by moisture. All metal components (e.g., mounting bolts, linkage pins) are zinc-plated and coated with an anti-corrosion finish, passing 500 hours of neutral salt spray testing without rust. Unlike unprotected handles that corrode or seize in wet environments, this design ensures reliable operation in coastal, snowy, or dusty regions for 5+ years. Backed by a 24-month warranty against manufacturing defects (e.g., handle cracking, lock jamming, key breakage), it provides Dongfeng KL truck owners with a secure, durable, and user-friendly door access solution
