Luckily for the toyota land cruiser forums, they have been having issues finding a smart key for their 2020+ land cruiser heritage model which has the same FCC ID as our 4th gen RX350s. I decided to take a small leap and buy the key in hoping it works, and it did.
Here are the part numbers I've ordered.

Here is the pic of the keys. They had no issues programming it at all. Nice and easy.
Thanks for reading! I hope this helps a lot of y'all!

See the two posts I quoted. I have a 2017 RX350 F-Sport and has been working flawlessly thus far.
So I did some more research on this, and ordered a key card for my 2020 RX 350 and can confirm success. I ended up ordering a key card with FCC ID HYQ14CBK. I decided to go with this FCC ID based on na1ddo's success above. While I'm not sure my methodology is correct, this is how I believed I had ordered the correct card key:
I looked up the Keyless Entry Module part number for my 2020 RX (899900E190). I took that part number to eBay and found a picture of the part which shows the model number is TMLF15-2, with an FCC ID of NI4TMLF15-2, which matches to the same model number/FCC ID as the 2017 RX keyless entry module that na1ddo has. I wasn't sure if mine would match or not since 2020 models and newer got a slight refresh. Based on this information I decided to give it a shot and ordered a key on eBay. I figured if it didn't end up working that seller (virginkeys) offers a 30 day return window. Programming was very easy in Techstream and took about one minute. I haven't used the card key much since programming, but I didn't have any issues with range and can unlock/lock easily with the card in my pocket.
I was initially going to purchase the key Kenvin had posted (FCC ID HYQ14CBM), and am not sure if that one will work or not. I messaged that seller (unlimitedpro13) asking to confirm if they do indeed program with the RX. I received this response: "Hello. We list our keys only from our experience. We successfully program these keys to 2020 and 2021 RX models" So it sounds like the CBM key may work, but unsure. Either way I'm happy knowing that the one I ordered is working, and thanks to na1ddo and Kenvin for posting and providing their assistance/success!
Not sure if this helps anyone, but the factory key fob that came with my RX, that FCC ID is 1551A-14FBB. It appears that the FCC IDs do not need to match in order for the key card to function.
I am trying Techstream with 2022 RX350, Techstream is asking for a passcode. Do you have a source for programming your card key
