I'd like to use this opportunity to wish all fanatics a happy holiday season and all the best for the coming year.

Which is the easiest way to solve dead battery issue on the E39 key?

Thanks in advance.

Diamond key or one of the old rubber keys?

Then you will have to break open the key de-solder the battery get a new one solder it back in and glue the key closed again.
Can't remember the type of battery but RS (http://za.rs-online.com/web/) sells them .
