What are the reasons why the trunk of a BMW X3 cannot be opened?

[SanGabriella]

The reasons why the trunk cannot be opened are as follows: 1. Linkage rod or lock cylinder issue: If the key is frequently used to open the trunk lid, the linkage rod may be damaged, and it can be repaired at a service station. If the trunk lid is always opened with the remote control, the lock cylinder may be dirty or rusty. Spraying rust remover into the lock cylinder a few times can help open it. 2. Not unlocked: The trunk is difficult to open because it hasn't been unlocked with the remote key. It's best to press the unlock button on the key before opening, or check if the key battery is dead. 3. Mechanical component failure: The trunk itself may have issues, such as broken wiring or other problems causing the trunk to not open. 4. Five-door vehicles generally cannot be opened from the inside: Some rugged off-road vehicles, to prevent accidental opening during driving which could cause casualties, usually do not have an interior trunk switch. Therefore, the trunk can only be opened from the outside.
