FYI the seat lock has a unique key. A stock bike will have matching locks for the ignition, seat and steering lock. If you get another seat lock, you need the key to go along with it unless you're extremely lucky and get a matching one. You can see the key number around the keyhole. Or you can drill out the tumblers and use your existing key. Honda may still stock those, if you order one from them, the lock comes with a key.
