What are the reasons why the Mondeo trunk cannot be opened?

[Nicole]

Mondeo trunk cannot be opened for the following reasons: Linkage rod or lock cylinder issue: If you frequently use the key to open the trunk lid, it may be due to a broken linkage rod. In this case, you should go to a repair shop to have it opened. If you always use the remote control to open the trunk lid, the lock cylinder may be dirty or rusty. Spraying rust remover into the lock cylinder a few times should help open it. Mechanical component failure: The trunk itself may have issues, such as a broken wire or other problems that prevent the trunk from opening. Key battery dead: The solution is to press the unlock button on the key before trying to open it, or check if the key battery is dead.
