The 812W97100-6284 Door Lock + Ignition Lock Cylinder + Fuel Filler Cap set is a critical security component group for the cab and chassis of SINOTRUK Howo trucks. It provides three matched locking points, all operated by a single key, so the driver can secure the cab and fuel tank with one convenient key.
This 812W97100-6284 set is precision-manufactured to exact OEM dimensions. The lock cylinders use hardened brass tumblers, the ignition cylinder matches the TX mechanical steering column profile, and the fuel cap seals tightly against the filler neck. Every unit is tested for correct key engagement and smooth rotation.
Common signs that a lock set needs replacement include a stiff or jammed door lock, a worn ignition cylinder that fails to turn, a missing or leaking fuel cap, and keys that no longer match all three points. Fitting a new 812W97100-6284 set restores convenient single-key security across the vehicle.
Whether you are repairing a faulty door lock, replacing a worn ignition cylinder or renewing a lost fuel cap, the 812W97100-6284 set delivers the quality, reliability and durability that SINOTRUK Howo professionals expect.
The 812W97100-6284 lock and cap set is designed for SINOTRUK Howo trucks, with primary compatibility across the TX, A7, T7H, HOWO 371 and HOWO 380 series fitted with the TX mechanical steering column. It is a direct OE replacement, so it installs into the original mounting points without modification.
This set is essential in applications where vehicle security and fuel protection are critical, such as long-haul transport, construction, mining and municipal service. In these duties, the locks must operate smoothly despite vibration, dust and temperature extremes, and the fuel cap must seal reliably.
When replacing the lock set, it is recommended to inspect the door latch mechanism, steering column housing, fuel filler neck and key cylinders for wear or damage. The 812W97100-6284 is designed to work with the factory security system, ensuring correct key alignment and reliable operation.
For fleets with multiple HOWO trucks, standardising on the 812W97100-6284 lock and cap set simplifies security maintenance and ensures the correct matched set is available for scheduled service or emergency key replacement.
Replacing the 812W97100-6284 lock and cap set is a moderately simple procedure that requires basic hand tools and care with trim panels. This work should be performed by a qualified technician. Begin by disconnecting the battery negative terminal as a safety precaution.
For the door lock, remove the inner door trim, release the cylinder retaining clip and withdraw the old cylinder. For the ignition cylinder, remove the steering column shroud, insert the key and depress the release pin to slide the cylinder out. For the fuel cap, simply unlock and unscrew the old cap.
Fit the new 812W97100-6284 components into their respective positions, ensuring the retaining clips and release pins engage correctly. Refit the trim panels and reconnect the battery. Test each lock with the matched key, confirming smooth operation and secure locking at all three points.
For ongoing maintenance, periodically lubricate the lock cylinders with a graphite-based lock lubricant and check that the fuel cap seal is intact. If a lock becomes stiff, inspect the cylinder and latch mechanism before replacing the set again.
The 812W97100-6284 lock and cap set is manufactured in an ISO 9001-certified facility using hardened steel, brass tumblers and reinforced polymer components. Raw materials are sourced from certified suppliers and undergo incoming inspection for hardness, plating thickness and dimensional accuracy.
Each set is assembled on precision lines and then tested for key engagement, cylinder rotation, lock retention and fuel cap sealing. The keys are cut to the correct profile, and the tumblers are checked for smooth operation. Every set is subjected to a functional test before packing.
Random samples from each production batch undergo environmental testing, including salt spray, thermal cycling, humidity exposure and vibration, to validate long-term reliability in heavy-duty truck applications. These tests ensure the lock set continues to perform in the harsh conditions experienced by SINOTRUK Howo vehicles.
We back the 812W97100-6284 with a comprehensive 12-month warranty against material and workmanship defects. Our rigorous quality control ensures that every lock and cap set delivers the same fit, function and durability as the original factory component.
