What are the reasons why the trunk cannot be locked with the remote control?

The reasons why the trunk cannot be locked or closed tightly are as follows: 1. Reason one: Overly stiff spring rods are used to allow the rear hatch to automatically rise after pressing the opening switch; 2. Reason two: The matching between the closing limit rubber block and the locking mechanism is inappropriate; 3. Reason three: Malfunction in the trunk control circuit; 4. Reason four: Failure of the trunk hydraulic support rod; 5. Reason five: Damage to the trunk lock. The trunk structure is very simple, consisting of a motor + gear reduction mechanism-driven rod that activates the trunk locking mechanism, and its working principle is the same as that of the central door lock. You can go to a 4S shop to replace the new lock.
Recently, my car had the same issue—the trunk wouldn't lock with the remote, which really stressed me out. I took it to a mechanic, who checked and found several possible causes: first, the motor in the trunk lock mechanism might be broken, preventing it from responding to the remote signal; second, there could be poor wire contact or a short circuit, blocking the signal; third, the trunk might not be fully closed, so the sensor thinks it's open and prevents locking; or the key fob battery might be weak, making the signal too faint to lock. I tried closing the trunk firmly and testing again, but it still didn’t work, so I had to get the wiring inspected. The mechanic warned that if this happens often, it could compromise anti-theft security and should be fixed ASAP. He suggested regularly cleaning the lock to prevent jamming or replacing the lock motor. After solving the problem, I also remind everyone to routinely check if the trunk opens and closes smoothly. Bottom line—don’t delay fixing this, or you risk losing items or safety hazards.
