My 75 firebird has issues with the Ignition, sat for years and got it running using a remote start button and all that because the keys were lost. Got a new cylinder and keys to try and when installed still wouldn't turn. Took it back out and the new cylinder works fine, but the actual Ignition will not budge. Any tips? Can't get it to move and don't know how to get it freed up or what's wrong with it. Is an automatic floor shift and the steering wheel is not locked.
