That being said if you bought it new from a dealer, you should at some point be getting a second key from Toyota, many 2023 models due to supply shortages were shipped with only one key, recently Toyota is starting sending the second key via the dealers starting with the earlier production vehicles first and going to the latest.

Even if you bought it used from a dealer I'm guessing you maybe able to get the second key if it was never sent/given to the previous owner.

Either way you may want to post this in the 5th Gen forum section for more views/replies.
