I think you should probably download an owner's manual and a service manual. Both are available on this site if you join as a premium member, or you can just google for one.
You will need to take your ski to a dealer and have a lanyard programmed for the ski, we have a member who also offers this service, you will need to remove the MPEM and send it to him and then he can program a key for you. PM Nick [MENTION=41828]Minnetonka4me[/MENTION].
