Steve have you got the service manual and handbooks with the car.
If so it will be in there if not call a dealer with your reg and they will sort you out.
Its usually on a small card with the handbooks. If you dont have it get in touch with a Honda dealer, might have to show v5 reg doc to prove your the owner I guess. You might also want to check you have the locking wheel nut code also, Honda should have a record of that, in case you lose the key nut.
Accords have one locking wheel nut on each wheel for theft prevention. Each car has a different locking wheel nut key. There is a code to identify it, so you can order a new one from Honda if you lose it.
