Thanks for the info guys. I pulled the ignition cylinder out last night and was able to pull the tumblers out. There is a small metal piece that moves out of the way when you put the key in. That piece was filthy and gummed up. I simply wiped the excess away and replaced the cylinder and the key moves in and out very easily now. I did end up lubing the cylinder with the lock lube / deicer when I was finished. I think I might get the lube from Toyota later.
