    TLDR: the Lexus credit card key works and CAN be programmed for your smart key equipped Tundra. I got mine to work on my 2020.

    There are several write-ups on other Toyota forums such as the following:

    Tacomas - https://www.tacomaworld.com/threads/lexus-credit-card-key-working-in-tacoma.445979/

    Highlanders - https://www.toyotanation.com/thread...highlander.1114266/#/topics/1114266?_k=csobay

    Parts list (from the Tacoma thread; not confirmed for Tundra, but my key works):
    -Key part number: 89904-53511 or 89904-53512
    -Make sure Key says Denso model 14CBB or FCC HYQ14CBB
    -Works in through 2020 with smartkey.
    -Buy an extra Battery, CR2412
    -Emergency Key (slide in mechanical key) part number: 69515-30350

    Abbreviated process:
    1) Using Techstream connect to vehicle as Lexus LX570 3UR-FE
    2) Open up immobilizer/Smart Key ECU
    3) New key can be added via Smart Key registration following the wizard. Note that if you'r using a previously assigned key, you'll have to reseed key via a locksmith or DIY via a 3rd party website like weboctopus.nl. This process is a bit more complicated, so I'll save that for a dedicated post below.
    4) Follow-prompts until registration shows complete.
    5) Done!

    No more carrying a set of keys/keyfob. I just keep this in my wallet, so I'll never forget my wallet and/or keys anymore.

    Do you lose the use of one of your key fobs if you do this? I think Toyota has a limit of two keys programmed for a vehicle.

    No, you can program up to 5 fobs.

    I have a full function scanner that may be able to program the key to my 2020 Tundra. I have a question about the model of the credit card key. Are the part numbers you gave mandatory or does the credit card key just have to say "Denso model 14CBB or FCC HYQ14CBB"?

    Honestly, I’m not sure. Those part numbers were from the Tacoma world thread. My key has both of those listed, but I couldn’t tell you if other models or frequencies will work or not.

    OK cool. I am looking forward to hearing from people who were able to erase a fob before it is programmed. I am going to double check my scanner to make sure it has the key programming function. I am pretty sure it does.

    Any of you guys with a programmer in the Southeast? Preferably the Gulf Coast of Alabama, Florida, or Mississippi?

    I erased my 2 fobs using the smart code erase option. It took 16 mins for the process to complete in Techstream. The programming of the 3 keys was fast and simple afterwards.
