I guess this issue is way beyond my pay grade because I can manually open my trunk by depressing the trunk lid button whether the doors are locked or unlocked, and whether I hit the trunk unlock button on my remote or not it doesn't matter it opens. In summary as long as I have the proximity key with me the trunk opens by manually depressing the button regardless of any other scenario. That being the case I really have no idea why there is a trunk release button on the keyless remote. It doesn't trip the lock on the trunk, to me it does nothing other than flash the lights .???
