The reason why the trunk can still be opened after locking the car is that the car is in a false lock state, or there is a trunk malfunction. The specific reasons are as follows: The car is in a false lock state: The door lock and the trunk are two independent components. If there is a trunk lock button on the remote control and someone is using a car lock jammer, the trunk can still be opened after locking the car. The so-called car lock jammer is a signal blocker that emits electromagnetic waves to shield the electromagnetic waves of the car remote, causing the car to be in a false lock state. Trunk malfunction: If the trunk can still be opened after locking the car, it is necessary to check whether the trunk has a malfunction that prevents it from being locked. Also, check whether the trunk switch button on the key is stuck or damaged, making it impossible to lock.

I've encountered this situation several times, where the trunk can still be opened after locking the car, usually because the trunk itself isn't fully closed, causing the latch not to engage properly. For example, sometimes when parking in a hurry, the trunk lid isn't pushed shut firmly, or there might be luggage stuck in the gap, rendering the lock ineffective. Additionally, the electronic locking system might malfunction. If the car has a remote key, low power or nearby interference sources, such as mobile phone signals, can cause the car lock to be unresponsive. Also, mechanical lock components, if rusted or worn—like a bent or rusted latch—can fail. I recommend always listening for a clear clicking sound to confirm the trunk is closed properly. If not, try manually checking the lock or quickly visit an auto repair shop for adjustment to prevent theft—safety first.

This issue is quite common. From an electronic perspective, the trunk being able to open after locking is likely related to the vehicle's intelligent system. For example, the remote control part of the car key may not be aligned with the sensing area, or the may be running low, weakening the signal and making the car think the key is still nearby, thus allowing the trunk to open. Some cars have anti-pinch mechanisms or incorrect safety settings, such as a memorized opening position, which can result in incomplete locking. Additionally, if the vehicle's battery is aging and the voltage is unstable, the electronic control unit may malfunction and operate the trunk lock incorrectly. I recommend first replacing the key battery, then checking and resetting the vehicle settings, or testing away from interference sources. Regular maintenance should include attention to system updates for prevention.

From a safety perspective, many vehicles are designed with emergency trunk release features to prevent entrapment, such as interior trunk buttons or pull cords that allow unlocking. Therefore, the trunk may still open after locking due to accidental activation or aging components, as the internal mechanism isn't disabled. Safety-wise, this issue poses risks like theft or property loss and should be promptly addressed. It's advisable to check for obstructions or loose buttons inside the trunk—common faults that require immediate repair if found.

I think it's quite simple that the trunk can still be opened after locking the car, most likely the key was left inside or the trunk button is stuck and unresponsive. Some car remote locks are not very sensitive, or the vehicle is old with loose parts. I've tried checking if the trunk lid is securely latched when locking the car, if not, try another locking method or ask a friend for help. Usually a minor issue.

From everyday experience, I guess that the trunk can often be opened after locking due to setup issues or minor equipment malfunctions. For example, the remote control buttons may fail, or the vehicle's automatic locking might not engage the trunk part, especially in cars with keys where such bugs are common. Other reasons include dead batteries or interference affecting signal processing. I suggest manually testing the trunk's response to locking. If that doesn't work, try replacing the battery, or simply maintaining and cleaning the lock components to save money and prevent issues.
