What is the reason for the trunk not locking when remotely locking the car?

Here are the reasons why the trunk does not lock when remotely locking the car: 1. Use of overly stiff spring rods: Overly stiff spring rods are used to allow the rear hatch to automatically rise after pressing the opening switch. 2. Component matching issue: The closing limit rubber block does not match the locking mechanism properly. 3. Wiring fault: There is a problem with the trunk adjustment wiring. 4. Support rod failure: There is an issue with the trunk hydraulic support rod. Faced with the situation where the trunk cannot be closed, most car owners can only try to close it with more force. If it is indeed caused by the above reasons, using more force will only increase the damage. The correct approach should be to drive the vehicle to a repair shop for inspection. If the door cannot be locked, a simpler method is to use the spare mechanical key to lock it.
I've encountered this issue a few times, likely because the trunk lock mechanism is loose or obstructed by foreign objects, preventing it from closing tightly and thus not locking. Additionally, if the remote key's battery is running low, the signal weakens, and the car may not receive the command, or the signal could be blocked by strong interference nearby, such as high-rise buildings or large metal structures in the parking lot. Sometimes, the trunk's design itself can be problematic—sensors might malfunction, like the components that detect whether it's properly closed getting dirty or damaged, causing the system to mistakenly think it's not shut and refuse to lock. I recommend regularly cleaning the trunk tracks during maintenance to prevent dust or water from corroding the parts. If you do run into this issue, it's best to have a professional mechanic check it with tools—don't force it, as that could damage the car and compromise safety. At home, you can try replacing the key battery or reprogramming the remote system, which usually resolves simple faults.
As a tech enthusiast, I believe the issue mainly lies in the electronic control system. Remote locking relies on signal transmission, and if the trunk won't lock, it's likely due to a depleted key fob battery—try replacing it with a new one. The car's 'brain,' the control module, might malfunction if interfered with or programmed incorrectly, such as when exposed to rain or extreme heat. Faulty sensors could also be the culprit, with dust or debris blocking the trunk switch and confusing the sensor. I always say signal interference is a common pitfall—parking near WiFi routers or high-voltage power lines can cause trouble. If manually closing the trunk doesn't work, take the car to a 4S shop immediately to check wiring and fuses before a major issue arises. To protect the signal source and extend its lifespan, avoid keeping the remote in a crowded pocket during daily use.
