reflash computer
 

getting code p0633 invalid skim key. just had command start put in. code started when i used starter. i cant find anyone to reflash computer until at least tomorrow. need to leave for work out of town in th am. can i reflash it and how. took battery terminals of for half hour. any ideas

Why do you need to reflash it? Is your truck not starting? I had the same code when my remote starter was installed. I drove it like that for days before I got around to clearing it with my Smarty. If you jut need the code cleared (or want it cleared) you can go to an autozone and use their scanner.

my truck now shifts into drive and reverse gears with a clunk and you have to hold the brake. second you let off, your doing 30 without touching the throttle

So what rpm is your idle? Did this all happen since your command start? go talk to the installer if so.

rpm and idle is fine. started when i first used starter. need to go to work 600 km away befor installer is open to look at it.
