Please help with AC2 and ACBH physical copy

I think you can redeem them somewhere, but better to contact their support

I think you must redeem them on Uplay in order to play.

Does it say on the box you should activate them on Uplay? Though if it doesn't work, you could probably contact Uplay support and they should give you a working key, its what i did with Mass Effect on Origin

I try to contact with support :) thanks for all guys
