Default TPMS non-OEM sensors

I have 2ea. Dorman 974-033 TPMS sensors to install on my 2007 Lexus rx350, but I have been told that only Toyota/Lexus can do the changes because of proprietary rules by Toyota. Is this correct? What should I do next or Any suggestions?

The Dorman TPMS Sensors should be fine as long as you are certain you have the correct part.
I installed a Dorman AFS Sensor on my RX330 4 months ago, functions perfectly.
Always satisfied with Dorman products, used many of them on previous vehicles also.

350 uses a newer system than 330. Mine had to be registered to the system by techstream. If u have techstream, u can do it, otherwise Toyota or Lexus dealer for it to be initialized and registered in ecu.

I had a dead sensor on my 07 350 and took it to Discount tire. They replaced it with some aftermarket brand that allows them to clone the ID number, no Techstream involved. $60 out the door. Works just fine.

Discount Tire is the way to go. They have all the scanners etc. Without the cloning method and just install the sensor, ecu wont read it on 350s.
