I've got a 92 convertable, when switched off, sometimes the key doesn't come out. Haven't seen anything in my shop manual regarding this particular issue. To be more specific when it will not switch all the way to the lock position (the ign sw), I can still move the gear shifter, and sometimes I can move it back to drive and then to park and it comes out. If I try to switch it (the ign sw) back to on and off, this activates some kind of anti-tampering device, which stops the vehicle from starting. After a short while (10 min to 20 min) it will restart.
I suspect there is a cable from the shifter that allows the ign sw to go to the lock position. A local shop swears the ign sw is the problem. If I was to pay the cost of a ign sw replacement, I'm sure they would come to find the cable will still need to be adjusted. This is where I have a problem of paying for parts that arn't needed.

On another issue, if anyone knows how to disable this anti-tampering device, please pass it on. Our local dealers are willing to learn about it, no matter how much shop time it takes.

Most of the time it is stored and because of this situation it sits 11 to 11 1/2 months of the year.
The car I used to love has become a major pain.

Yes, there is a cable. I'm not sure about adjustment, as I have the 4+3 trans.....

Invest in a service manual. It is all covered in there.
