My car was at the dealer for 6 weeks waiting for a new skreem unit. I finally got tired of waiting and had it towed home with the thought of removing the skreem myself and sending it to SOS for reprogramming. I'm still concerned that the skreem may not be the problem based on how the car acts. It does not give me the "3 crank" routine. It won't crank at all! Should I go to the trouble and expense of removing the skreem and having it tested by SOS?
