you can do it yourself and it isnt that hard. there is something like a seven step process to do it...you start by pulling a fuse. you can do the whole process in less than five minutes. basically a series of commands by turning the key in the ignition and such...a dealer can do it , but many including myself have done it. After reading that you have an 05 I am unsure of the process for that year...so I apologize if I was incorrect. I do know that you can do that for the 97-03's for a fact though yourself
