If you are having SKREEM problems I suggest using "SOS diagnostics" near Portland Oregon. Look them up online. I diagnosed a no start problem with the help of this forum to be the SKREEM. I had the SKREEM & ECM removed and sent them along with our only key to have repaired by SOS and have 2 more keys cut and programmed to the system. We saved over $2500 for what the dealer wanted to do and got 2 new keys in the process.
