TPMS programing...

[04denaliXL]

I just got new tires and a new TPMS and I need to find out how to program it so my service tire monitor warning goes off. I saw the dealer can do it with a device which I don't have obviously. I also heard you can do it by putting it into discovery mode and lowering air pressure in the tires and inflating them going clockwise around starting at LF tire. Is this accurate? Or do I need to have dealer do it? It's a 04 Denali btw...

Thanks
