Johnny- no problem, I appreciate the quick reply.
I’d like to improve my OP:
I have the key to my RT
I have a used top case from a K1100 that I want to rekey to match my bike. I don’t *have* the key to this massive top case. I have a picture and a tracing, and can drive the 30 minutes back to the seller’s house to use the key he still has. He neeeds to keep it. At least for a while.
