Ok everyone, I need to know if this is normal or how can I disable this feature. this is a 2006 Titan xe. If you unlock the door with the key remote and open the door, and do not start the engine, after 30 seconds or so, (i have never Timed it) the doors automatically lock back! This has cause me to lock my keys in the truck twice now! Any idea how to get rid of this feature? It is very annoying!
