If they are the Suzuki luggage, the locks come with a new bike, they would usually be under the seat or in the info pack.
The locks do not come with the luggage pack, you need the original lock that were supplied with your bike.
I'm not sure if Suzuki do the lock sets now, I know they never used to and it was a pita for people buying boxes off ebay without locks and the original owner of their bike would keep the lock when trading the bike.
