Welcome aboard.

Could be ignition switch, bad sector, bad or out of adjustment safety neutral switch. Floor shift or on the column?. Has the column been apart recently?

 

Hi, its a column shifter and no it hasn't been touched. The car sits a lot. I start it/move it every month or 2 sometimes.

 

Where the steering column runs through the firewall in the engine compartment try pulling up on the linkage that runs down to the transmission it could be slightly out of adjustment or bound up at the steering column where it hooks up, only takes a little movement.

 

It’s pretty common for the cap over the springs and wafers to come un-staked over time. When it does, this exact situation occurs. The fix is to replace the ignition lock, or if you are so inclined, to re-stake the cap.

 

If it's a tilt column, one thing that's very common to break is the Rack.
But then the ignition wouldn't work if that was the case.

 

grab the column where it goes under the dash and twist it counter clockwise to get the column in the position to turn the key further, good luck!

 

You beat me to it!! Welcome to the board and hope this helps!

 

HI, left this project in my garage for a while and just got too it. After pulling the steering and getting the lock out I notice that I still can't take the key out even with the lock in my hand. It's jammed and won't turn. I would guess that means that all I have to do is replace the lock itself and put it back together.
I notice many places online selling lock replacement.
My chevelle is all original and i want to make sure I don't degrade the value. Would I need to replace the door locks as well to match the key or would you try and re-key (if thats possible) so that the key matches the door?
any thoughts?
thanks in advance

 

IF you want to keep it original, take it to a locksmith.

 

If you have a column shift, there is something wrong with either the lock rod to ignition switch (down on the lower column) or the alignment of the ignition switch. It sounds like the ignition switch may be moved away from the lock position and keeping the key from being rotated back fully to the off position. I’d unbolt the ignition switch and see if it will allow the key to work properly.
