another question about keyless entry

I have a 2000 4-Runner SR5. I bought it used from a Toyota dealer with awful customer service. I'm certain it must have been a repo as I only have a silver keys for the vehicle that work fine but stick a little when you use them in the ignition. I have a hunch that it has factory keyless entry and I'd like to try my hand at programming it with a genuine Toyota remote (found some on Ebay that I'd like to buy) and I found the instructions on this site. My question is, will the programming work if I don't have a factory key with a computer chip in it? Thanks!

Yes - there is no chip in the plastic keys
