[QUOTE="Creedence85, post: 247030, member: 4346"] Did they replace the steering column lock or did they do the updated TSB to bypass the column lock? On Corvetteforum.com many people in the US are reporting that this is the only solution offered by some dealers as GM is no longer making the parts. I'd recommend looking into it further and asking your dealer about the updated TSB as this is probably the fix that should have been offered. The column locks are notoriously unreliable and will eventually fail again. The aftermarket bypass modules can have unreliable relays which fail and then have to be replaced.

I'm also thinking of going the simpler route and just having the BCM reprogrammed to not activate the column lock, forgoing the replacement of the locking plate and unplugging of the column lock, as my column lock is still working and should stay in the unlocked position and not function once reprogrammed. The 2005s are a bit twonky with the column lock and the shift to reverse function.
