2001 AUII ute immobilizer problems

[FuriousFord]

Charged battery last night and after performing another diagnostic test today using FORScan the results were the same as the last diag test on the picture I uploaded yesterday. Results identified the same issue with DTC (PCM-P0443). Does this mean I need to do a parameter reset on the PCM? If so, do I need two keys to perform the reset or can I just use the one and only key I have?

Like I stated previously, I am no auto-electrician/technician so I am depending on you guys to assist with determining what needs to be done to make sense from the FORScan results.
