Hi there my names Frank. I had lost my key and didnt want to spend all that money to buy a new one.So my brother has the same exact one as I have. His was totaled in an accident. So what I did was to pull the computers off of his and swapped them out of mine.I even changed out the key cylinder.My RR ran fine no problems but now everything turns on fine cranks over but wont turn on. My dash does not say anything is wrong everything looks exactly like it did before. I was told by doing this it would work but to my surprise it did not. Is there anyone out there that can guide me in the right direction?Any help would be greatly appriciated .
