So...I got new rims...got new EZ Sensors installed on them by Discount Tire..they said the system was working correctly and driving 20 mins/20 miles would make the light go off. Well it's been 4 days now and a couple hundred miles and those dang lights are is still on.
I did a search and realize that we can use the satellite buttons on the left of the steering column and initialize the sensors...did that...light still on. I also didn't realize before they installed them that there was a main/2nd set of TPMS setting's. So I'm 100% sure it was left on the main setting when they put them on. Wouldn't when they install the new sensors just override the main setting or no? Or could taking it back to them and have them set it up under the second setting work?
Unfortunately I live in the middle of nowhere Texas and there are no Lexus dealerships within a 3hr radius of me or I would just suck it up and go there. There is a local Toyota dealership but they said they didn't think they couldn't help me, they didn't even know what an IS-F was. I was asked multiple times when I rolled up there if it was a 250/350 with badges I threw on there lol.
Anyways, my question is there anything else I can do?? I assume resetting the ECU would do nothing? Would taking it back to discount tire and having them re-register them under the 2nd set of wheels setting make a difference or not? I would think the EZ Sensors they installed just override the main setting but apparently I'm probably wrong. Thanks for any help/advice.

The Toyota dealership uses the Techstream laptops.. (same as Lexus)
You would need the 4 registration codes (7 characters long) to input into the system as the 2nd set..

Not sure what EZ sensors are ?? or how they work inconjuction with the oem system..
Did you call or go back to Discount Tires ??

Discount told you wrong. The TPMS low pressure indication/fault code set will never go away on its own (by design) unless you have the sensors in your garage and they tell your TPMS everything is OK. When you drive 20+ miles away, they'll indicate a fault again. Discount needs to fix the problem or get sensors that work with a Lexus. There's nothing unique about the F, any Lexus uses the same sensors, so it's pretty odd they'd screw the pooch like this, but anything is possible.

Yea this Toyota dealership is very special to say the least. I may have to tell them the process of going about this although they should be the experts about this stuff, not me.
I haven't gone back to discount yet because I am trying to figure out what the issue is. They made it sound like the EZ sensors were designed to work with any vehicle (universal) and they can be programmed to any vehicle.
The light on the F says Low Tire. If it says low tire that sounds like it's reading the sensors or at least A sensor. Would the dash say something completely different if it wasn't reading anything from the car TPMS wise??
It sounds like I am screwed then if this Toyota dealership can't/won't do it. Can discount tire just take off my OEM sensors from stock wheels and make a rebuild kit for them and put the stock ones back on the new rims instead of the EZ sensors?
I appreciate all your help guys. I hate seeing this freaking light and warning messages every time I get into the car.

It sounds like I need to contact discount tire and see if they can dismount the TPMS sensors from the stock wheels and make a rebuild kit to put those in the aftermarket wheels.

Why didn't Discount use your old sensors? They wanted to sell you new ones? Sounds like they need to make it work properly. Discount has a device to program the TPMS ECU - if they don't, that's the root of the problem. There is no such thing as a "universal" sending unit, because the system is designed to work with a unique code for each wheel. Lexus isn't nice enough to tell you WHICH wheel that is, even though the TPMS ECU could tell you.
Anyway - DISCOUNT Tire is your real trouble maker here, not Toyota. And I'm not bashing Discount at all - I buy tires from them all the time.
The rebuild kit is cheap and available from Lexus or Toyota. Part number is 04423-0E010, retail price is $7.04.

or
Option B is to buy another set of OEM TPMS sensors and have them installed & inputed as the 2nd of TPMS sensors.
Like I mentioned in my post.

When I went in that day for the new wheels, they said that the cost to dismount the stock wheels sensors and put them in was almost the same cost as getting new ones, so I said screw it, might as well just get new ones and have two sets for the vehicle. I thought it would be easy to program a new set in.
Yea Lobux, I have bought all my tires since I've owned a car through them and have never had problems at all. Maybe cuz all of my vehicles never had TPMS sensors till now lol. jk. Wive's H3 never had a problem.
They said they used their device and programmed them to my vehicle and that it worked fine the day I got them. I just got off the phone with them, unfortunately they are about to close in 10 mins, so I have to go tomorrow and they said they will try to register them again or do what they can to fix it. If that does not work I assume I will have to bring in the stock wheels and have them make a rebuild kit to use the stock sensors. I will see tomorrow I guess.
I'll let you guys know the outcome.

Yea JoeZ you are probably correct. EZ Sensor link below.
http://www.ez-sensor.com/
I don't want to have to shell out more money for new sensors unless discount would refund the money for the set I bought though.
It's so annoying to get in the car and see a huge LOW TIRE right in the middle of the gauge cluster at all times lol

I'm actually hoping they can resolve your issues. I'd be perfectly happy to have EZ-sensors in my wheels as long as they work. I'd been looking at them as a potential option for a second set of wheels for track duty.

I hope they can resolve it too. It sounds like a great alternative to being forced to go to a dealership. We'll see if they can reprogram them or do what they gotta do to make them work with our vehicle tomorrow.

WOW, I'm soooo confused... I purchased a second set of wheels for my winter tires (that didn't come with TPMS's) so I purchased a set of Pacific TPMS's to put in them for $100. When I take them to a wheel specialist place to put them in the rims and have the tires put on, do I/they need to write some registration code numbers down to put in the car's computer somehow? (Also my TPMS's don't have a 7 digit number/letter combo on them... but do have a few sets of id #'s of some sort).

There is no universal sensor, period. Depending on the car manufacturer, TPMS differ on the frequency they use. Toyota brands (Lexus, Toyota, Scion) work on the same frequency, so getting sensors for any car from these manufactures should work for the ISF. Once installed, all 4 codes need to programmed into the car by the Lexus/Toyota dealer. Again, they should match the frequency that the car's receiver uses.
I don't know how much you paid for these sensors, but if they told you that dismounting the OEM sensors would be as expensive as getting theirs, then they lied. OEM sensors are actually part of the valve stem's structure, so removing them would be as easy as unbolting them once the tire is removed.
For my second wheels' set I went to eBay and purchased a brand new set of Scion TPMS (paid $50 for the set), they were exactly the same as my OEM Lexus TPMS. I gave the codes to my Lexus SA and he programmed them in less than 5 minutes.
Depending on the dealer the programming task may cost you some money. One of the Lexus dealers in my area asked $150 for the job, I drove to the next Lexus dealer and got it done for free.
Finally, if you have the message LOW TIRE it means that a tire is under 30 PSI. It doesn't mean that it's reading the sensors because the lack of a sensor would be the same as LOW TIRE. I know because I drove without sensors for some time and I got the same message.

Thx for your input Juanca. Like I said I'm kind of assed out since there is no Lexus dealership anywhere close to me or I would just go there. If this doesn't work with discount tomorrow I will have to try Toyota again even though they look at me like I'm speaking Japanese when I ask for their help lol. I
I forgot the exact quote they gave me for undoing stock rims and moving them to the new wheels but it was close 2 the sensor price, maybe they were hooking me up with a discount cuz I'm military or w/e IDK. These EZ sensors should work though, maybe the guy that programmed them the 1st time didn't do it right.
lol @ LOW TIRE message even when there are no sensors present, thats pretty funny.
