I am wondering why a screwdriver and a push button to start it? There might be quite the list of problems that have facilitated the use of those items to start that Sami. Swaping out the ignition switch is not the simple job I thought it would be when I tackled it but it is doable for sure. I'm not sure about your area but around here it is quite possible to find a nice Sami with a top and working key switch in the $3000 price range. Good luck however you decide. c
