Ign lock cylinder barely turning

I no longer can get the ignition key to come back from ON to acc or off position, the key does'nt even have to be used for it to turn, it goes from on to start and the car starts and runs normally. it barely turns back enough to kill the engine when attempting to shut off the car. I obviously need a lock cylinder, anything else I might need on hand when that gets replaced?

The ignition switch is not in the column so you shouldn't have to worry about that...

Re: ign lock cyl barely turning

It may not be the cylinder at all.
The cylinder turns a plastic gear, which in turn moves a brass (?) sector gear (straight flat shaped) that actuates a long rod that is attached to the ignition switch on the top side of the column.

Your ignition switch could be gummed up or worn out. There's a strong spring inside it that is what makes the key cylinder return.
The plastic gear and sector gear could be gummed up or worn. I had an issue sort of like that and it turned out the brass rod gear (not sure I'm using the right names) was bent! I could only turn the key so far.
I would pull the steering wheel and disassemble the column. Jim Shea has great GM steering gear papers available that will help.... check them out here: http://jimshea.corvettefaq.com/?cat=4

spray some wd40 into the lock and see if it frees up.
I also had an ignition switch wear out and bind on me so I would check that too.

Re: Ign lock cylinder barely turning

its tilt, but the column is really tight. I'll be addressing it later today, maybe the lube in the lock cylinder will help. Im now on a dead alternator problem and gotta get the bugs out fast, its 90 degrees here today !!!
