Just put my 2003 CTS in the shop to replace the alternator because the Service Electrical and Service charging System light came on. I assumed the alternator was bad because the last day I drove my car, the volt readings went from 12 Volts to 10 in a matter of 15 mins, then the car would not start. The battery was 2 months old so took it back to Oreillys and they replaced it. Now the car is still at the shop with a new alternator, but the anti-theft system is engaged. The car will start, radio works, ect but can not get it out of park or able to remove the key. A service guide states using the key-less entry will disengage the anti-theft, but the repair shop is saying that's not working. Any ideas as to what I need to do?
