I bought one off ebay, the round key type. honda wanted like 300$+ for the stock one I paid 70$... the locking mechanism swaps over to your wiring harness (three small screws that hold the harness to your lock) you might be able to make the wiring work but thats beyond me.
The only issue is if you use your front tire lock the park brake stays on, I don't use it.
part was off
