Can't get the key to link to the seat memory???

I looked and can't find an answer to his one.
My '19 Tundra Platinum has seat memory that supposedly can be linked to the key so that the seat returns to the memorized position when the door is unlocked with the FOB.

The owners manual states...

A desired driving position can be recalled linked with the unlocking of
the door.
■ Registering procedure
Record your driving position to button “1” or “2” before performing
the following:
Turn the engine switch off and close the driver’s door.
While pressing the button “1”
or “2”, press on the wireless
remote control until the
signal beeps.
The driving position is recalled
when the driver’s door is
unlocked using the wireless
remote control and the driver’s
door is opened.
To prevent unintended triggering of the alarm, open and close a
door once after a driving position has been recorded. (If a door is
not opened within 60 seconds after is pressed, the doors will
be locked again and the alarm will automatically be set.)
In case that the alarm is triggered, immediately stop the alarm.
(P. 85)

I've tried this several times and cannot get the key to link. Does anyone know the correct way to do this? I also tried using the door unlock switch on the drivers door as there are other Toyota models that use that instead of the FOB but that will not work either.

 

That’s cool if you can get it to work. Wonder if it’s the same on the 2nd gens. I’ll have to have my parents try it on there truck.

 

So far everything that I tried does not work. Hopefully someone got it going.

 

I had to resurrect this thread because I believe I have found a solution for anyone else encountering this problem. I too followed the instructions in the owners manual perfectly with my 2021 Tundra Platinum. I figured out that it does work if you press the unlock button on the door and NOT THE KEY FOB. You do have to use the Key FOB you want to link the seat position too to unlock the truck and have it inside the cab while you work this procedure. I discovered this after watching a fairly recent video how to pair the FOB with a memory seat position in a Lexus.
