Does Anyone Have Two Keys To Share For Me and a Best Friend Who Now Go to Separate Schools?

Me and one of my best friends used to play a ton of Dota back in the day on the good old Frozen Throne. We now go to separate schools and don't see each other very often and he's expressed interest in playing this with me. I think it would be great if someone would be nice enough to share a couple keys with me so we could play together! Cheers!
