Now am a little confused, seen to have gotten the wrong part number from scan tool.170 820 18 26 is the immobilizer behind the dash. Where I need to check is the at the pump to see if it is getting the proper signals.
Antitheft dows not seem to work but if try to start three times and fails it must be reset before will try again. Everything seems to point to SKREEM not being there at all but instrument cluster seems to be glued in place so hard to remove. Since all I need to do is to be able to lock/unlock my need is different. Guess I was misinformed. Apologies.

OK new radio arrives tomorrow so need to remove anyway will pull the swtich panel and instrument the lock/unlock system. May be able to control there.
