Mine does this 2

if i lock the car, the trunk will lock and i cannot open it, however i can "DOUBLE" lock it, which means when i unlock the car, if i double lock it, the trunk will still be locked


i just lock the car, never do i lock the trunk seperate, b/c locking it by the door handle locks the doors, trunk, and fuel tank
