If it's an auto
I think there a cable going to the switch/trans, it's on the firewall
(I don't remember exactly where or if it was adjustable, It's been way to long)
the trans needs to be in park/pulls on that cable, to return the key to off
or it won't come out also, sometime a lil' pressure on the shifter may help too...
don't quote me
or
like
@guy gadbois said in a 4 speed,
shifter needs to be in reverse,
IIRC pull up on the T handle deally on the shifter shaft,
it was a reverse lock out
I think it's the same type of deal that cable on the firewall going to the ignition switch
that the autos have...
If that makes any sense, going on memory, not so great...
the round key operates the lock box & the glovebox, doors IIRC
square key is the ignition (& IIRC, the alarm out on the fender, if it has it)...
the tumblers in the columns on the ignition switches
are notorious for messing up too
there's a few deals on-line (Corvette forums & general info)
"how to fix the old one so you can use the key" or to get the key out
involve some disassembly, putting the key in Acc position,
& remove the lockset, a lil' finess & grinding
some said just a lil' WD40 down the tumblers, not so sure about that one
Good luck...
