A good locksmith can do almost anything with a lock.
On the way back from the 2013 Ulysses AGM I lost my keys to the Classic trailer lid. This was somewhere between Nymboida and Ebor, didn't miss them until we checked into the hotel-motel at Uralla - Top Pub (great pub, check this link:

Anyway, a locksmith at Tamworth (

Five minutes later he handed me a key, said "Try that", I did, it worked, he cut me another one and only charged me $20:00.
As suggested above, get the bike and pannier to a locksmith.
