So awhile back i did a 1999 4.6 to 2002 5.4 swap, keeping the coil packs. I am converting to the 2002 harness (COPs) and i have the 5.4 PCM that came with the 5.4, problem is, i do not have the key that was for the 5.4, and i only have 1 key for my own truck...

What is the easiest way to program my key to work with this PCM? My goal is to not have to trailer the truck to the dealership. Can it be done through my SCT X4? Thanks in advance
