Which Fob do I need?

[rayz02]

I'm the proud new owner of a 02 4runner Limited that came with a lot of keys but no remotes. I've been through the fob programming procedure and I get the lock and unlock at the end of the procedure like I should. Looks like there are 2 possiblities for remotes? A 4 button and a 2 button? Will either work? Any way to tell which remote is needed? THanks!!
