Product Intro:

Dongfeng H30 Lock Block Front Door Left (Part No. 5721000)

What This Part Is

What It Does

1. Controls Locking & Unlocking: It’s the part that lets your left front door lock (to keep the car secure when parked) and unlock (so you can get in/out) smoothly. 5721000’s internal bits stay tight, so you won’t have issues like the door popping open by accident or being hard to open/close.

2. Keeps You Safe: When you’re driving, it keeps the left front door locked tight—no chance of it swinging open from vibrations or bumps. It also works with the car’s anti-theft system, so no one can break in easily when 5721000 is locked.

3. Tells You Lock Status: If your car has a central control system, 5721000 sends signals to let the dashboard know if the left front door is properly locked. That way, you won’t drive off with the door not locked all the way.

What’s Great About It

• Fits Like the Original: First off, 5721000 is made to match Dongfeng’s original standards exactly. Its size, where the screws go, and how it connects to the door—all spot-on for the Dongfeng H30’s left front door. You can swap your old one for 5721000 directly, no cutting or drilling needed.

• Tough & Long-Lasting: It’s made of strong engineering plastic and reinforced metal. 5721000 can handle wear, rust, and hot/cold weather—no cracking, bending, or breaking, even if you use it for years.

• Works Smoothly Every Time: The little parts inside 5721000 (like pins and springs) are made precisely. Even after locking/unlocking thousands of times, it won’t get stuck, feel loose, or slow down.
