So that I don't waste anyone's time, I got the problem solved.
Thanks for looking; but, I finally figured it out that there are many varied videos and sets of written instructions on the 'net on how to program the Toyota fobs and almost none of them specify a year or a model on which their instructions work or don't work.
I finally found a set of instructions that worked for me at this site. It worked for both my 01 and 03 Siennas:

As an aside, I bought the 03 Sienna three days ago and it has only 8192 miles on it (eighty-one
hundred) and I have the Toyota dealer service records that verifies it. And I got it for what Kelly Blue Book says is $2000 under market for a private sale, $9470.
