I repaired the problem myself. It seems that the theft deterrent module will lock out the ignition system if the ignition key becomes too worn, or the key cylinder gets too sloppy. The really irritating thing about the whole deal, was that the relearn process Chevrolet gave me for the theft deterrent module did not work. I finally figured it out for myself, with the help of a few people that I know in the automotive repair business. The Impala has been working perfectly since, Thank God for small favors. Here's the TDM relearn sequence that worked for me:
Insert ignition key, turn to crank position and then back one click to run. Security light will flash 6 times and then flash to battery. This will continue for about 9 min. 35sec. At this time security light and battery light will flash alternately. Repeat process two more times, takes about 30 minutes. The fourth time you hit the crank position, the car will start.
