I have an old Saab Sonnet and we lost the key. How do we disengage the steering lock to get the steering wheel to turn in order to load it for transport?

My guess would be to remove the lock cylinder which would allow you to turn the switch with perhaps a screwdriver.I am not sure how the lock cylinder is removed but quite often as on early Mercedes there is a small hole on the cylinder that opens when the key is turned to the "on" position and a fine wire inserted ito the hole will release the cylinder. I will have a look at my Sonett 2 V4 and see if I can how it might be removed.
I did take a look but the 11 Sonett does not have the steering wheel lock system and the cylinder is quite different.

I don't know if the older Saabs are like the 900, where one key fits everything. If this is the case, remove the lock cyl from the door or trunk/hatch and take to a locksmith to make a key either from the number code on the cyl or from the tumblers them selves.
About as much work as disassembling a steering column and the end result fixes the problem once and for all.
