Guys, Looking for some advice - Just picked up a 2010 Challenger RT for my son - I have both of the original key fob (5 button) which came with the vehicle when new - I would like to have a additional key fob as a spare. Car has remote start (5 button fob) - If i purchase the correct fob online, can I program it myself without a visit to the dealer. Are there any identifying info on the fobs (FCC info im guessing) that would ensure I am purchasing the correct fob. Any suggestions would be greatly appreciated! Thanks to all and Happy New Year!
