having just gone thru this last week, with a fellow on the COG forum, that bought a bike with a destroyed ignition lock, and NO keys whatsoever, but he did manage to find a brand new "old stock" ECU/FOB set, for like $300.. (yes, he was extremely lucky on that one...)
the locks and keys, sold in a "group" are under this part number (Note: this is not including FOBs and ECU...)
see below;
the parts "grouping" that covers that complete set of locks, with keys; (ignition switch, gastank lockset,both bag latch/lock assemblies, and seat lock: with 2 keys for each except 1 for the ignition, all keyed alike) is
p/n 27045-5395 SWITCH-ASSY and costs $1150, but mind you, that set also includes both saddlebag latch assemblies, with keys..
just tossed it here for reference...because it keeps coming up.
