I have 2 diablo 2 cd keys but 1 expansion cd key, can two people play at the same

time but share an expansion key?

My friend and I, after deciding that diablo 3 was not as fun as we thought, decided to play diablo 2 once again.
Unfortunately my friend lost his cd keys a long time ago and purchased diablo 2 without the LoD expansion. Myself, having a cd key AND a expansion key, is wondering if i can share my expansion cd with him and be able to still play at the same time.
Please answer if you know this! He is on vaca and is returning in a week

Thank you!

 

no not expansion anyways u can both play non xpan but you would still need another xpan cdkey to both play.
