I am having problems with mine also. I can not get it to extend the time from 10 minutes to 20 minutes. I have done exactly like the book says, but the engine still shuts down after 10 minutes. I also have a problem with the remote not working at all after the second time I start the engine. The only way to get the remote to work again is to actually get in the truck and start the engine. then the next time I use the remote it work but again only twice. I am going Friday to the dealer to see what can be done.
