I had this same problem. Its the the VATS system, in the key hole, thats not making good contact with the little resistor on your key. I took it in to the dealer and it was about $350 to replace the ignition cylinder, and two new keys(ugly GM one, not the gold ones with the cadillac emblem). If you do go to the dealer tell them straight off just to replace the ignition cylinder, this way you save the $84 diagnosis fee. Search this forum for "wait three minutes," some people had other fixes that worked for them.
Try cleaning the keys or try your spare set first, or bypass the system. I just had mine bypassed. All you have to do is get resistor(s) that match the resistance of the chip on your key. There are two very small wires encased in a tube that looks a lot like another wire (mine was orange) leading from the ignition switch. cut the wires and put the resistor across them. I had an friend's brother who does auto alarms do it and he only charged $50 to do it at my house. He had to come out and do it because I put it off until the car decided not to start at all. While he was there, he put in a remote start system. Don't delay, you never know when the car will decide to cut off completely instead of making you wait a few minutes. Mine died on the street during a snow storm, and I had to push it into the garage so he could work on it !!
