I ran across this same problem on a stock unit on a Pontiac grand prix.
only had one key and tried everything and the key would not program and set theft codes call TAC ( tech. assistance center) found out through them that on the Grand Prix and Monte Carlo they use the older style key a PK3 key not a Circle + key I got an older key and it programmed right away , the TAC guy told me that it is due to 2 diffrent company's making the theft systems the old ones were Delphi and the new ones are made by Seminems.
and the keys are not interchangeable.
