Saab: 96 SAAB 900 convertable, saab 900, recurrence

Question
I cant seem to turn the ignition switch its on the lock position but i wont turn....help!

Answer
The problem is in the console below the key...there is a spring loaded [reverse lockout] lever whose circular spring occasionally breaks, resulting in the condition you describe.
The console must be disassembled and the spring replaced, or alternatively, if you don't mind NOT having the reverse lockout feature, removing the lever and spring completely, and thus forever avoiding a recurrence.
