Toolbox Lock Cylinder 3704970LE640
,JAC N56 N75 N80 N90 N120 Lock
,OEM Toolbox Lock with 2 Keys
The Toolbox Lock Cylinder 3704970LE640 is a direct-fit OEM replacement designed for JAC N56, N75, N80, N90, and N120 trucks. This lock cylinder secures the toolbox compartment, preventing unauthorized access to tools and equipment stored on the vehicle. Supplied with 2 JAC-branded keys and backed by a 3-month IZUMI aftermarket warranty.
The lock cylinder is inserted into the toolbox latch assembly and operated by a key. When the key is turned, the cylinder rotates a cam or lever that engages or releases the latch mechanism. A worn or damaged lock cylinder — indicated by stiff key operation, broken tumblers, or lost keys — prevents the toolbox from being secured or opened, creating a security risk for stored tools.

- Product Type Confirmed: Russian catalogs describe it as "Замок инструментального ящика" (toolbox lock). The product label confirms "行李箱锁" (luggage lock) and "工具锁芯" (tool lock cylinder).

- Brand & Warranty: IZUMI aftermarket brand available; 3-month warranty offered.
- Packaging & Lead Time: Neutral box, color box, or custom branded packaging; delivery 15–20 days after payment; small orders accepted.
