Door Lock + Ignition Lock + 2pcs Fuel Tank Cap 812W97100-6194 for Sinotruk Sitrak Trucks

When your Sitrak heavy-duty truck sits idle because of a faulty door lock, a worn ignition cylinder, or a leaking fuel tank cap, every hour translates into lost revenue. That is exactly why Mettlead engineered this complete Door Lock + Ignition Lock + 2pcs Fuel Tank Cap kit (OEM 812W97100-6194) as a single, matched-key solution. Instead of sourcing each component separately and risking mismatched keys, you receive a factory-direct set that restores full cab security and fuel system integrity in one shipment. Built to genuine Sinotruk Sitrak specifications, this kit eliminates guesswork for fleet managers, procurement teams, and workshop technicians across Africa, the Middle East, Southeast Asia, and Latin America.

Key Features and Benefits of the 812W97100-6194 Lock and Fuel Cap Kit

One Key Fits All — Unified Security Design

This complete set shares a single key profile across the door lock, ignition lock, and both fuel tank caps. Consequently, drivers carry fewer keys, dispatch teams simplify key management, and the risk of unauthorized fuel access drops significantly. Moreover, a unified key design reduces wear on driver pockets and ignition cylinders over the vehicle’s lifespan.

OEM-Grade Material and Precision Machining

Every lock cylinder is manufactured from hardened zinc alloy with anti-corrosion plating, while the fuel tank caps feature reinforced nylon seals tested against diesel exposure and UV degradation. As a result, these components resist the harsh vibration, dust, and temperature extremes typical of long-haul routes.

Direct Replacement — Zero Modification Required

Because this kit replicates the original Sinotruk Sitrak factory dimensions, bolt patterns, and wiring interfaces, installation requires no drilling, trimming, or adaptor brackets. Technicians typically complete a full cab lock swap in under 45 minutes, which means your truck returns to service the same day.

Fuel Loss Prevention

The two included fuel tank caps seal tightly against evaporation and spillage. Furthermore, their locking mechanism deters fuel theft — a persistent challenge in remote transit corridors where trucks park overnight without surveillance.

Application Scenarios and Compatible Vehicle Models

This 812W97100-6194 Door Lock + Ignition Lock + Fuel Tank Cap set is specifically designed for the following Sinotruk Sitrak heavy-duty truck platforms:

• Sinotruk Sitrak C7H — Long-haul tractor units operating on intercity freight corridors
• Sinotruk Sitrak C5H — Medium-to-heavy distribution trucks for regional logistics
• Sinotruk Sitrak G7 — Next-generation cab platform for premium fleet operators
• Sinotruk Sitrak C9H — Heavy-haulage and construction-site transport

Whether your fleet tackles 12,000-kilometer trans-continental routes across West Africa, navigates dusty mining roads in Central Asia, or handles port-to-warehouse shuttles in Southeast Asia, this lock and fuel cap kit keeps cab access secure and fuel reserves intact. In addition, fleet workshops that service multiple Sitrak variants can stock this single part number to cover the most common lock-replacement scenarios across several model years.

OEM and ODM Capabilities — Tailored to Your Market

White-Label and Custom Packaging

Mettlead understands that distributors and regional wholesalers often need products under their own brand identity. Therefore, we offer complete white-label packaging, including custom box printing, branded hologram stickers, and multilingual installation guides. Whether you supply 200 sets to a single fleet customer or stock 5,000 units for retail distribution, our packaging line adapts to your requirements without inflating your lead time.

Strict Quality Control Process

Before any lock and fuel cap kit leaves our facility, it undergoes a rigorous 5-step inspection protocol:

1. Raw material composition verification (zinc alloy purity, rubber hardness testing)
2. CNC machining tolerance audit (±0.02 mm on lock cylinder bore)
3. Key insertion cycle test (minimum 10,000 smooth rotations)
4. Fuel cap pressure-seal test (no leakage at 0.3 bar for 60 seconds)
5. Matched-key cross-verification across all four components

This disciplined approach ensures that every kit arriving at your warehouse meets or exceeds the original Sinotruk factory benchmark. In other words, your end customers receive reliability they can trust from the first turn of the key.

Flexible Order Quantities

Whether you are a small independent workshop ordering 10 sets or a national distributor placing a container-load order, Mettlead accommodates. We maintain ready stock for popular Sitrak lock kits and offer scheduled production runs for large-volume OEM contracts.

Customer Case Study — Solving Fleet-Wide Lock Failures in East Africa

In early 2024, a logistics company operating 120 Sinotruk Sitrak C7H tractors across Kenya and Tanzania approached Mettlead with a recurring problem. Over 35 trucks had experienced ignition lock cylinder seizures and fuel tank cap seal failures within the same quarter — likely due to a batch of substandard aftermarket parts sourced previously. The fleet’s procurement manager needed a Door Lock + Ignition Lock + Fuel Tank Cap 812W97100-6194 Sinotruk Sitrak replacement solution that was both cost-effective and genuinely reliable.

After reviewing their requirements, we shipped 40 complete 812W97100-6194 kits with custom fleet-branded packaging. Installation across all affected trucks was completed within two weeks. Six months later, the client reported zero repeat failures, a 100% reduction in fuel theft incidents (thanks to the locking fuel caps), and a noticeable improvement in driver satisfaction because of the smooth single-key operation. Subsequently, they placed a standing quarterly order for an additional 30 kits to cover preventive maintenance schedules.

This case demonstrates how sourcing genuine-spec Sinotruk Sitrak door lock and ignition lock sets directly from a quality-controlled factory like Mettlead eliminates the costly cycle of repeated aftermarket failures.

Frequently Asked Questions — 812W97100-6194 Door Lock + Ignition Lock + Fuel Tank Cap

Does this kit use a single key for all four components?

Yes. The door lock, ignition lock cylinder, and both fuel tank caps are keyed alike. You receive two identical keys with each 812W97100-6194 kit, so one serves as a driver spare.

Will this Sinotruk Sitrak door lock and ignition lock set fit my specific truck model year?

This kit is engineered as a direct OEM replacement for Sitrak C7H, C5H, G7, and C9H platforms. However, because Sinotruk occasionally updates cab hardware between production batches, we recommend confirming your existing part number against 812W97100-6194 before ordering. Feel free to send us a photo of your current lock assembly and we will verify compatibility within 24 hours.

How do the fuel tank caps prevent diesel theft?

Each fuel tank cap features a keyed locking barrel integrated into the cap body. Without the matched key, the cap cannot be unscrewed or pried open without visible damage. Additionally, the internal NBR seal creates a vapor-tight closure that prevents both theft siphoning and evaporation losses during extended parking.

What is the expected lifespan of the ignition lock cylinder?

Under normal operating conditions, the zinc-alloy ignition cylinder is rated for a minimum of 50,000 key-turn cycles. For a truck started 4–6 times per day, this equates to roughly 8–10 years of service before any mechanical wear becomes noticeable. Periodic lubrication with graphite powder can extend this further.

Can I order only the fuel tank caps or only the door lock separately?

While this listing covers the full 812W97100-6194 matched set, Mettlead can supply individual components upon request. Keep in mind, however, that ordering the complete kit ensures key compatibility across all access points. If you need individual parts, contact us with your requirements and we will prepare a tailored quotation.

What packaging options are available for bulk orders?

We offer neutral packaging by default. For distributors who require branded boxes, custom labels, or regional language inserts, our white-label service covers the full scope. Minimum order quantities for custom packaging typically start at 50 sets, though we remain flexible depending on the project scope.
