like I told you swap over the pats chip in the key to your old keys and that should work. Only reason to swap cylinders is to swap over the pats code so the computer sees it. That is if these chips aren't glued in...
IIRC that is the only reason but I could be wrong.

Since I know one day you want a SCT tune, you could just have 2 keys fo now then put your old pcm in when you want a SCT tune and your back to your old keys and everything...
