First, let’s keep it straightforward—this isn’t just a “lock for the trunk.” It’s the
all-in-one assembly that keeps your Tiggo7 Pro’s tailgate (truck lid) secure and easy to open/close. Mounted inside the tailgate,
right where it latches to the rear body, it works with your car key, inside unlock button, or even the hands-free sensor (if your Tiggo7 Pro has it) to control the tailgate. Its main jobs? Lock the tailgate tight so it doesn’t pop open while driving, unlock smoothly when you need to load/unload, and sometimes trigger a warning if the tailgate isn’t fully closed (to avoid cargo falling out). Without it, your tailgate might rattle, stay stuck, or open unexpectedly—super risky for both your stuff and road safety.
This lock assembly is made only for the Chery Tiggo7 Pro—always check your VIN to be sure! It’s designed to fit like a glove: its shape matches the Tiggo7 Pro’s tailgate internal space (no forcing parts), its locking mechanism aligns perfectly with the rear body’s latch (no loose tailgate), and its wiring (for electric unlock) plugs directly into the car’s electrical system (no cutting wires). Grab a generic one? You’ll run into headaches: it won’t lock/unlock smoothly, might not work with your key/button, or could leave the tailgate loose—defeating the whole purpose of a lock.
It’s all about security and convenience—here are 3 key things it does for your Tiggo7 Pro:
Locks the tailgate tight: When you close the tailgate, the assembly’s metal latch clicks into the rear body’s catch, holding it firm. Even on bumpy roads or when braking hard, it won’t budge—so your cargo stays safe.
Unlocks easily (multiple ways): It connects to your car’s key fob, the inside dashboard button, or hands-free sensor. Press a button, and the assembly’s small motor (or manual lever) releases the latch—no struggling with stuck locks.
Checks if it’s closed: Some versions have a tiny sensor that tells the car if the tailgate isn’t fully latched. If it’s open, your dashboard might show a warning—so you don’t drive off with a half-open tailgate.

This 554000109AA lock assembly only works for the Chery Tiggo7 Pro—wrong fit = tailgate trouble:
Fits These Models: All Chery Tiggo7 Pro variants (matches the tailgate size, latch position, and electrical system—confirm via VIN). Works for both manual and electric unlock versions (just check if your Tiggo7 Pro has hands-free or not).
Won’t Fit These:
Other Chery models (e.g., S5, A13): Their tailgates have different latch positions or electrical setups—this assembly won’t line up.
Non-Chery vehicles: Even if it “looks similar,” the lock size or wiring won’t match (can’t lock the tailgate or unlock with your key).
While it’s not super complex, getting the latch aligned right is key—DIY might leave the tailgate stuck:
Access the old assembly: Techs remove the small trim panel inside the tailgate to reach the old lock, then disconnect the wiring (if electric) and unbolt it.
Mount the new one: They line up 554000109AA with the tailgate’s mounting holes, bolt it down, and plug in the wiring (if needed). They test the latch a few times to make sure it aligns with the rear body’s catch (no sticking).
Test fully: They close the tailgate, unlock it with the key fob/button, and check the dashboard warning (if any)—ensuring everything works smoothly.
Clean the latch quarterly: Wipe the metal latch with a dry cloth to remove dirt or rust (dirt makes it stick—hard to open/close).
Lubricate once a year: Put a tiny bit of silicone lubricant on the latch (not oil—it attracts dirt) to keep it moving smoothly.
Check wiring (electric models): Every 6 months, make sure the wiring plug is tight (vibration can loosen it—unlock might stop working).
Test the safety sensor: Close the tailgate halfway and check if the dashboard warning pops up (if not, the sensor might need adjustment).
