just wanted to thank you all, for the precious help I recieved..
i went to my mechanics, (it was actually funny, I called him this morning, starting to describe the problem, and he immediately interupted me, and said:whatever you do, if the car happens to start, DO NOT TURN IT OFF....)so, I drove it there, he had a used ignition tumbler that he lends to people like me, so, he slpapped that in, in 5 mn and ordered the new one..so, I go back there when he recieves it...
it is still $90...I am actually tempted in getting one on ebay ($30) and just have different keys for the ignition and the doors...
anyway, thanks again!!!!!this forum is great.
