the ones from ACE already have all of that info programed in its a plug and play computer.

Ditto. Your concerns are answered here:

Remanufactured

there about 5k for the device alone, that doesnt include the subscription for files from each car manufacturer on all the diagnostic n flashing info.

but i did find some new info, u do not have to have the keyless entry/anti-theft info programmed into it as long as the vin is correctly written to the new pcm. the lack of the keyless entry/anti-theft info on the pcm will cause a DTC-P0633, i do not believe it will trigger the check engine light though. the car will work but that code will not go away until that info has been programmed onto the pcm. u can leave it with out that info or find out how much chrysler or garage(if capable) will charge u to do it

Thanks for all the replies with information. I'll let you all know how it works out once I order the part and swap it into the car~

You folks are all awesome here!

THANKS VERY MUCH!!!!
