i have searched found that this is an invalid skim key, but the truck runs fine....only a couple of hard starts, but other than that nothing unusual....what would cause the truck too throw this code?? and should i run it too the dealer?

 

Mine threw the same code, no trouble running, a couple of hard starts and I've never tried to use anything but the factory key. Any ideas??

 

My 05 threw it all the time!!! Just cleared it with the BD downloader and keep rolling!!
