Subaru central lock cannot be opened due to poor contact points or wiring issues in the central lock system. Poor Contact: There may be oil stains, debris, or foreign objects on the contacts; prolonged use may cause surface oxidation; arc erosion can lead to defects, burrs, or the formation of metal particles; or there may be jamming in the moving parts. Solutions include: For oil stains, debris, or foreign objects on the contacts, wiping with a cotton cloth soaked in alcohol or gasoline can help. If the contacts are made of silver or silver-based alloys, the formation of an oxide layer or minor burns and blackening due to arcing generally does not affect functionality and can be cleaned with alcohol, gasoline, or carbon tetrachloride solution. Wiring Issues: Poor contact at the connection points between the busbar and other equipment can interrupt circuit operation. A fault in a section of a circuit during electrical equipment operation can cause a line break, blocking current flow and leading to abnormal conditions in related components of the electromechanical equipment. Any wiring issue can have a certain impact on the entire electromechanical working system. Solutions: If using the remote to unlock the door, the remote battery may be dead, or there may be strong signal interference nearby. The remote key usually contains a hidden mechanical key, which can be used instead. If the mechanical key cannot open the car door, the central lock system may be in an electronic lock state, or the door lock cylinder may be stuck due to prolonged use and cannot be turned. The first situation requires waiting one or two hours for the lock to release before attempting to unlock again. The second situation may require forceful measures, such as breaking the window to open the door, or contacting a 4S shop for repairs.
