Hello, I have a friend who has an 03 vette and wants the anti-theft turned off. I was able to disable the anti-theft and make the vehicle drivable again but I can-not figure out how to keep the instrument panel from Flashing "SERVICE COLUMN LOCK". I disabled the the anti-theft and the steering lock. The car was damaged in a crash and lost battery voltage for about a month and when it was repaired and put back together ( By Him ) the vehicle would start and run but when you tried to drive it the ECM killed the engine. Any help on how to get the "SERVICE COLUMN LOCK" off the instrument panel or another way to fix the anti-theft would be awesome. Thanks.
