TPMS Inoperable

Upgraded my GL wheels to the 20" wheels from an 09 GL320. Was told that all the new wheels had TPMS. Left tire place and no TPMS light so I thought everything was good. Drove about 15 miles and TPMS light came on saying "Tire Pressure Monitoring inoperable". It doesn't give me an option to reset or do anything. Does this mean none of my wheels have TPMS? Does it mean 1 failed? Trying to figure out what I need to do without going on a wild goose chase.

Thanks
