If you go to your dealer with the wireless key they can supply and code one or two more passive keys for you. Don't lose your current key though, do that and you are screwed. The keys given away with the panniers can start your bike, be careful. Get two more passive keys and get the dealer to link them to your bike. Only three keys can be paired at any one time and this will remove the other two keys linked to your bike. Test both the new passive keys before you leave the dealer to prove they work.
