Seeing as how some of us massy-chists are still running these awesome finicky b****es, then please forgive me for committing the "sin" of replying to an old thread....
My '85 P-type sat for 5 years (long story for another thread) and then I tried to get some keys made. Local dealer told me I had to pull out my passenger door handle to get the lock cylinder number off the inside. Fine (**grumble**). I got it, put it all back together too quickly due to threat of a thunderstorm, then the door locks started their phantom dance - talking to me in the yard while I was working on other projects. "click*** clickclick***click."
The first time I got locked out leaving the key in the ignition, I was lucky - window was down. But then the alarm started going off with certain key-lock combos, big PTA, and then I realized that soon I was going to get stranded somewhere back in the sticks where I live forgetting to pull the unobtainable key out of the ignition with the window up and have to break an unobtainable window, and realized that the car had declared war on me.
I checked this thread and a couple others and definitely have some things to check out - especially whether I damaged the lock-position sensor when I pulled the passenger door handle out.
However, I am at a time in life where life is trying to kick my butt and I don't have the time or stamina of some of youse younger youts to fight this gremlin yet. So here's my "old-man" "got-you-you-b******" solution:
Six months ago I simply pulled out the door-lock relay from near the brake pedal - put it away for safekeeping, and then began enjoying life. Now I have manual door locks (like we had when I was a kid), and I am happy as a clam, with no complaints. Massive functionality restored to my car with the added benefit that I get to be a gentleman and unlock the passenger door from the outside for my lady-friends. Life is good again. Just pull the dang relay and forget it.... (my two cents)
