The reasons why the trunk of a Lexus 570 cannot open automatically include issues with the linkage rod or lock cylinder, failure to unlock with the remote key, etc. Here are the specific explanations: Linkage rod or lock cylinder issues: If the trunk is frequently opened with a key, the linkage rod may be broken, and you should go to a repair shop to have it fixed. If the trunk is usually opened with a remote, the lock cylinder may be dirty or rusty. Spraying a rust remover into the lock cylinder a few times can help open it. Failure to unlock: The trunk may be difficult to open if it was not unlocked with the remote key. Before attempting to open it, press the unlock button on the key or check if the key battery is dead. Mechanical component failure: The trunk itself may have issues, such as a broken wire or other problems that prevent it from opening.
When my LX570's trunk suddenly stops opening automatically, I usually start by checking the electrical components. A blown fuse is the most common issue—the trunk motor typically has a dedicated fuse, which might be located in the engine compartment or the fuse box under the driver's seat. If the fuse is intact, the problem could be a faulty motor or poor wiring contact—issues like aging wires or short circuits can occur. Additionally, low battery power in the key fob can interfere with the signal, causing the trunk to malfunction. I recommend using the spare key to manually open the trunk as a temporary solution, but it's essential to visit a professional repair shop as soon as possible. Don’t forget regular maintenance, such as cleaning dust around the trunk latch to prevent sensor blockage. Insufficient battery voltage might also slow down the system's response, so using a multimeter to check the current is a necessary step.
