What are the reasons why a car trunk cannot be opened?

[DakotaLynn]

Reasons why a car trunk cannot be opened include issues with the linkage rod or lock cylinder, failure to unlock, or mechanical component failure. Below are detailed explanations and solutions: 1. Linkage rod or lock cylinder issue: Solution: Take it to a repair shop to open. If the trunk has always been opened using the remote, the lock cylinder may be dirty or rusted. Spray rust remover into the lock cylinder several times to open it. 2. Failure to unlock: Solution: Press the unlock button on the key, or check if the key battery is dead. 3. Mechanical component failure: Solution: Repair the faulty component. The trunk itself may have issues, such as a broken wire or other trunk-related problems causing the trunk to not open.
