This left rear door lock block is exclusive to Dongfeng H30—always check your vehicle’s VIN to confirm fitment! Dongfeng tailored it to the H30’s specs: its latch size matches the door’s strike plate (locks securely with a “click”), its internal gears align with the H30’s door handle rods (smooth operation), and its wiring (for electric locks) connects directly to the car’s central locking system (no adapters needed). Grab a generic lock block or one for other models? You’ll face issues: loose locking (door pops open), stuck doors (can’t open from inside/outside), or incompatible wiring (electric locks don’t work).
Core Jobs: Lock Securely, Open Smoothly & Sync with Central Locking
Keep the door locked: When you press the central lock or turn the key, the lock block’s internal latch snaps into the strike plate—holding the door tightly closed. It won’t budge even on bumpy roads, preventing accidental door opening.
Enable easy opening: When you pull the inside or outside door handle, the handle rods trigger the lock block’s gears to release the latch—letting the door swing open smoothly. No jiggling or forcing needed when it’s working right.
Sync with central locking: If your H30 has electric central locking, the lock block connects to the car’s system. Pressing the key fob or driver-side lock button locks/unlocks the left rear door along with all other doors—convenient and secure.
Fits These: All Dongfeng H30 variants (matches left rear door size, strike plate position, and central locking specs—confirm with VIN).
Won’t Fit These:
Other Dongfeng models: Like S30, AX3, or Yixuan—different door designs, latch sizes, or wiring (lock block can’t attach or work).
Non-Dongfeng vehicles: Even if similar in shape, their door handle rods and locking systems differ (no functional fit; may damage the door).
H30 with modified doors: Aftermarket custom doors change internal rod positions—original lock block won’t align (stuck or loose doors).
Prep: Disconnect the H30’s battery (avoids electric shocks if it’s an electric lock). Remove the left rear door panel (unscrew fasteners, gently pry off clips—don’t break the panel).
Remove old lock block: Disconnect the wiring connector (if electric) and unclip the linkage rods from the lock block. Unscrew the bolts holding the lock block to the door frame, then pull it out.
Install new lock block: Position 5821000 in the door frame, secure it with bolts, and reattach the linkage rods (clip them firmly). Plug in the wiring connector (clicks when secure).
Test & Reassemble: Reconnect the battery, test locking/unlocking with the handle and central lock (ensure smooth operation). Reattach the door panel, pressing clips back into place.
Lubricate yearly: Apply a small amount of silicone lubricant to the latch and linkage rods (avoids rust and jamming). Don’t use oil—attracts dust and debris.
Check for jamming: If the door is hard to lock/unlock, inspect the lock block for debris (wipe clean with a dry cloth). Stuck debris is a common cause of poor operation.
Test electric connections (if applicable): If the lock doesn’t respond to the key fob, check the wiring connector for corrosion (clean with a wire brush if needed).
Replace worn clips: If linkage rods feel loose, replace the small clips (they wear out over time—prevents rods from popping out).
