chemi you need to go to your local honda dealer and show them your registration and vin and such then they will give you the code then you turn the radio onn and it will say code then you use the numbers and put the code in the dealer will not give it to you over the phone because thats why they call it antitheft because i can steal a honda radio then call honda and get the code thn turn around and sell so you see it will defeat the purpose of antitheft
