How do you program a Toyota Sienna key?

I’ve been driving a 2008 Toyota Sienna for years without changing the key fob battery. I replaced the battery after it died, but now it doesn't work. I think I need to reprogram the key, but I don’t know how to. What’s the best way to program a Toyota Sienna key?
