Lexus LS460 trunk won't open with interior switch or key pad when engine is on, previously had trunk latch assembly replaced on Lexus LS460

Some Lexus LS460 owners report experiencing difficulties with the trunk not opening using the interior switch or keypad while the engine is on, particularly after having the trunk latch assembly replaced. These issues may stem from a malfunctioning trunk release mechanism that could be obstructed or damaged. Additionally, some owners find that resetting the Electronic Control Unit (ECU) can sometimes resolve the problem. It is also important to verify that there is a consistent power supply to the trunk latch assembly, as interruptions can hinder its operation. Moreover, those who have recently replaced the trunk latch assembly should double-check the installation and ensure all connections are secure. If these troubleshooting steps do not resolve the issue, seeking assistance from a professional technician or dealership may be necessary for a proper diagnosis and resolution.
