You have to reprogram the new PCM with the Ford scantool, performing a PMI or "programmable module installation." The info from the original PCM is downloaded into the scantool, then programmed from the scantool into the replacement PCM. You'll either need the scantool and knowhow to do the swap or let a shop with the scantool do it.

No, the new PCM needs to be programmed to accept the old keys.
