Bokch0y,
Amazon has the ATEQ QuickSet TPMS Reset Tool and the ATEQ VT30 TPMS Reset Trigger Activation Tool. I remember seeing that Tire Rack will ship a RX350 snow tire & new wheel combo with the sensors installed. Other places may do this too. I'm new to all of this. I just picked up a CPO 2010 RX350 to replace my 2000 RX300 that didn't have the sensors. I'm sure I'll be asking for help with this (which tool & how to connect) in the fall...
