I get my friend tomorrow to bring maxsys. Hopefully it would be fine after parameter reset and I’ll try to program second key because locksmith couldn’t even program it. I just change eeprom from original cluster the antitheft light actually normal now. Will post tomorrow.

My guess would be, If parameter reset is not working then its either a communication issue between cluster and pcm or the eeprom for pats sync in pcm is currupt/damaged.
Ok so pats codes it’s on the eprom? Tool said both key programmed but only master gets program not copy key. IC successfully just code 1260 comes up Thats the one disables engine. Is there a way to bypass pats ? To get the truck to starter right up.

Sorry not much more I could offer to help you with finishing this job other then send me the cluster, pcm and key(s) and I will send it back properly synced and programmed. I'm not that expensive.

Thanks for your help. It end up being ignition switch where immo is stored. Got new keys and programmed then pats. Started right up.
