The steel rims have a different angled sensor.
You can use a strap kit, build a pipe bomb, have the tire guys turn the sensors. Either way, you will have to break down your stock steel rims to get to the sensors then to do it to the other set if there is tires already mounted.
The ids off your steel sensors are programmed into the tpms ecu there is only room for 5 numbers.
If you buy just new rims, the strap kits work great, many members use them here and cost is aroun $50 plus whatever labor. A good tire shop should help you out.
As far as the lugs I have heard different info.
I know when I swap my tires/rims for winter, the lugs look different from oem steel rims to oem alloy. So I have a set for each.
The guys can explain it better.
