tpms / after markey wheels question and rant

[TTN4x4]

I bought Konig Coastal Chrome (20x 9.5) used with Titan sensors installed (the installed part is important here). At a local tire store, I have them dismount the oem wheels and take out "my" sensors so that I can sell the wheels and put the sensors in the Konig's. One of the techs tells the manager that the sensors wont work in those wheels. I try to explain there are already working nissan titan tpms sensors in the wheels but they belong to a friend and I need to get them back to him and put my sensors in the wheels. The guy argues with me "you cant put sensors in those wheels" Doesn't try to explain it or bother to look at the obvious tpms valve stems in the wheel.
Has anyone had experience with these wheels and tire sensors. Unless I am missing something I don't see how there can be sensors already in the wheels that work... but you cant use tpms sensors in my particular Konigs ??? Unless he thought he could buffalo me into buying some of his wheels so my sensors would work.
