read thr that pdf. There is something call key reminder door system, which if a door is open, when you hit the lock switch, it will lock but then unlock immediately. My pathy was acting like a door was open so i checked all the door sensors. Sure enough there was one door sensor (at the door which was somehow slightly misaligned caused by the prior owner, who knows what he did) that was not pushed in enough. It turns out that it seems to be pushed in far enough to turn off the door open light on the dash but not all the way enough to tell the system that door is close. So i folded up a piece of paper and taped it against the door and the sensor is now completely pushed in. sure enough, everything then worked as expected. turned out my old remote was also bad. But i was now able to program the new remotes. So everything is now good. The end
