I finally completed the engine/tranny switchover on my jeep.
I had previously asked for some help/advice from this forum and got negative or no advice.
After transplanting the engine and tranny, all I had to do was install the PCM,TCM and BCM from the donor vehicle.
The vehicle now runs and locks and unlocks with the donor vehicle ignition switch and key fob.
Thank you all.
Next project is to replace both front CV joints/axles and enjoy the drive.
Anyone interested in parts from a 2000 GC can get them for free, if available. Just pay for shipping
