'02 Santa Fe/Keyless Remote/Reprogram/Numbers

Hi everyone - new here, hopefully somone can help. The remotes, I need to reprogram and/or replace.

I tried reprogramming, it didn't work. I may need to replace them. The numbers are worn off of the remotes. Can I find the numbers elsewhere?

Research tells me I need the numbers, that I can't buy just "any" Hyundai remote.

Any help is appreciated.
