When I try to start the car sometimes I can put the key in and turn it and nothing happens, try again same thing happens. Put the key back in and it starts fine. This doesn't happen all the time. Had it at the dealer for 2 days and they couldn't get it to repeat my problem, yet when I first brought it in it happened in front of the service manager. They had it on the computer and it checked out fine. I tried a different key and it happened again today. I had the skim module changed at 30,000 miles for the same problem (under warranty). Jeep has 62,000 miles now and same mechanic worked on it again. Says nothing shows up on the computer. It started fine the last 2 days until today. I can't figure it out. Please help.
