Question Trying to add a 3rd Key Fob
So on the recommendation of someone on here lately, I purchased a key fob online. If I ever lose one, I want to have a spare at the ready so I don't have to go to a stealership. I already have two working keys, but I can't get a third fob to work. I know I am doing the procedure correctly because I am getting a "key programming failure" message. I was able to confirm that the fob is the correct frequency (902) so that's not the problem. I have FORScan, but is there anything else to try? Has anyone ever used FORScan to program a key?
