Key Fob for 2000 SR5?

[Roguestatus1688]

I have a 2000 SR5 4Runner. It came with power locks, sunroof...etc. When I purchased from the previous owner, I did not get a key fob for automatic unlock and lock. If I was to purchase one, would I be able to sync it up to work? How would I be able to find out if mine is compatible? Thanks in advance for the help!
