Check the key: Make sure that the key you are using is the correct one for your Corvette. If you have multiple keys, try each one to see if one works. If none of your keys work, you may need to have them re-cut.
Wiggle the steering wheel: Sometimes, the column lock mechanism can become stuck if the steering wheel is not in the proper position. Try jiggling the steering wheel back and forth while turning the key.
Check the ignition fuse: The column lock mechanism is powered by a fuse, so it's possible that the fuse has blown. Check the fuse box in your Corvette's owner's manual to locate the fuse for the column lock and replace it if necessary.
Check the ignition switch: If the fuse is not blown, the problem could be with the ignition switch. The ignition switch is responsible for sending power to the column lock mechanism, so if it's not working properly, the column lock will not release. You can try cleaning the ignition switch with contact cleaner or replacing it if necessary.
Check the steering column: If none of the above steps work, you may need to have the steering column serviced. This is a more complex repair, so you should take your Corvette to a qualified mechanic.
If you are unable to resolve the "service column lock" message, you will not be able to start your Corvette. It is important to get this issue fixed as soon as possible to prevent further damage to your vehicle.
