C5 column lock by-pass installation
Second, Richard at Compliance Parts that supplies the LMC5 is great to work with.
Going to a dealer would cost you a fortune and they will do the recall change that does not guarantee a fix - while the LMC5 parts are around $40 and it takes less than an hour. I'd call around to some of the Mom & Pop type places and see what they can do. (I've done two or them myself).
Good luck.
My car locked on Sunday, I ordered the part from them(Ebay store)( Search LMC5), and got it today and installed it. it was $46 and I paid for express shipping ($20). The dealer may charge up to $1000 dollars for this and it still may fail...

If you decide to take it to someone, perhaps a local Corvette club would have some recommendations.
Imagine the look on your mechanics face when the car doesn't start and you have to tell him u were digging around in the floor-board cutting wires, swapping plugs and messing with the ECU .... LOL
DO NOT attempt this unless you are qualified

PS: I assume you have a manual tranny since the autos in 2002 do not have a column lock feature.

I consider the LMC5 to be the best Column Lock problem permanent fix out there. It also does not require you to “undo” any previous CL attempts to resolve this issue. Their eBay ads have a good video that shows the install at the BCM. It does not cover everything in the written instructions. So, read the instructions and also here is some extra info. In some cases, the BCM timing is off just enough to cause some issues. They make several versions and they can swap out/provide one of these if you have any issues. Their customer support is as good as it gets.
Not uncommon for people to "put the column in a pre-lock condition" and not know it and then start with the install. In other words, they started with the column lock “energized’ even if it was not actually locked yet. If not actually locked yet, it will be as soon as you turn the steering wheel after the LMC5 install. It will then remain in the locked condition until you cause the motor to unlock. It will then remain in the unlocked condition since the motor is then unpowered with the circuits disconnected.
Here is one way to prevent that if your column locks and unlocks normally:
If the CL is functioning normally you don't not need the Unlocker, merely turn the ignition ON, pull fuse #23, turn ignition OFF, turn the steering wheel (left and right) and verify it is unlocked. Next, disconnect the negative battery terminal, re-insert fuse #23 and continue with the install.
Also the 1999 and later C5's have a column lock relay that can be unplugged or else it will be powered and could fail and drain the battery. The LMC5 written guidance provides this info. This relay is above the BCM.
