Replaced Smart Key Module cant program key now.
I have a 2017 Is 200T and recently had to replace the Toyota Smart Key Module 89990-53380 after breaking my original in a repair attempt.
I brought out a key programmer to the house and they were using Xtool device which resulted in many failed attempts.
Basically my car now has no active keys and am unable to program a new one without getting it into accessory mode which I cant without the key.
Does anyone know if a key programmer can solve this with the right tools maybe I just need someone with more experience? Or must take this to lexus? Any solutions or ideas or steps would be much appreciated!

use techstream, you should be able to connect to the car without turning it on. also if your module is brand new and no keys are on it, it should be in auto registration mode for two FOBS out of the box. That's how they assign fobs to cars in the factory.
if you got a used unit, you will need to do a Immobiliser Reset and it should be able to readd the fobs.

it says I’m required to get the technician reset approval request along with manager tis inbox and approve. Is this something I need to take it to the dealership for or call and request?

Thank you very much for the help and the link. I did purchase a used module so I’ll have to use the reset option. I’m completely new to this and trying to save any dollar I can do this question may sound dumb.

being that your module is used, it probably has old fobs programed to them.
so your best method DIY is to do a smart code reset. https://www.weboctopus.nl/lexus-scio...calculator.php is the web site where you buy tokens. you use a token key to generate the pass-code in the reset procedure.
1. buy 5 token (that's the cheapest they offer)
2. connect to techstream go to the smart key function and do a smart code reset.
3. follow the prompt and when it gets to the pass-code section. you will go to that web site above, enter your techstream version, vin of the car, the long seed number and enter your purchased token. it will generate a code. enter that code in techstream and it will clear the programed fobs. it takes 16mins for it to clear.
Once that's all done, that modular is ready to accept new/used fobs.
4. go to the smart key menu and go to registration or classic registration. from there, you should be able to add back your fob.
This is all from the top of my head. I've done this on prius and lexus.a few times.

dealer has access to creating seed keys to do a reset.
being that your module is used, it probably has old fobs programed to them.

everytime I get it to begin the reset it automatically fails immediately then causing me to have to get a new seed number and waste a mother code. I have one code I can calculate left. Any idea what the issue might be, it’s an instant fail and like I said I can’t turn the ignition on at all with this new module so I’m so confused on how this is going to work.

yes, when you do the smart key reset you add back your old fob.
https://www.youtube.com/watch?v=q-5oL3iNwBA shows you how then that weboctopus web site is where you generate the code.
https://www.youtube.com/watch?v=0ZfmOf0yGQY shows you how to add all the fobs back.

Which OBD2 cable are you using? I remember getting a similar error when trying to perform a zero point calibration, and from brief research, it might have been the cheap OBD2 cable I was using.

That's similar to the one I have, might be even the same. I'm not quite knowledgeable on why they can't program certain things. Maybe someone from the US can chip in on how much this would cost?
