Is it different for some cars? I thought this was the gx470 forum is it not the same on all gx470s? Are some gx470s programmed differently than others? And the only way to know is to inspect the spare valve stem? I just bought the car used with 200,000 mi no clue if its the original spare.
You can read the date code on the tire to see when it was made.
Most any tire shop should be able to scan all of the sensors for you and determine which ones are working fine, have a low battery, or a totally dead, and then replace them as needed. In my 2007, 4 out of 5 of the sensors were either low-battery or non-responsive. You could just have 1 or 2 that are messed up, or the all could be dead. Tire shops usually stock the sensors. They can't be replaced without at least partially dismounting the tire, so it's not really a DIY-friendly job. I think my shop charged $80 per sensor for the replacement and re-programming of the GX to read them. Since then, it's been super-nice not having the TPMS light on all of the time.
Did you have the system programmed to recognize the new TPMS sensors? Even if they are advertised as "pre-programmed", the GX won't automatically recognize them unless a scan tool is utilized to get the Lexus computer to pick them up.

They were supposed to be preprogrammed but the guy at discount tire said he did program them but the dash light wasnt going out. Car is at the dealer getting tran fluid drain and fill or id be looking for the "2nd set" tpms button right now.
The tire shop guy should have been able to tell if they were being recognized by the system or not. You might need Techstream or another advanced reader plugged in to troubleshoot the system.
The A/B button is on the lower driver's side dash.

He said they were, i havent had a chance to drive it 10 miles or fiddle with the 2nd set button yet. Drove straight from tire shop to dealer to have trans filter/fluid, transfer case fluid and PS flush done. Should have it back by Thursday.
