The keys are cheap at Lowes or Home Depot. I don't remember the key blank number. Most of the time they will activate the locks but not crank the bike. I used the rubber ends made for metal furniture feet and a 50/50 epoxy mix that hardened like metal. I have two, one for the bags in the rear, it is larger cause it needs to stick out a bit as the key hole is recessed. Another more flush mount for the right side that opens the center cubby. Gas cover is really not needed as the right side one is very easy to remove and open the gas cap.
