We have been through this before. It seems the ignition/door key number tag is invisible as is the locking wheel nut key sticker referred to on page 34 (last paragraph) of the service book.
Door/ignition key = 4 digit number prefixed by a letter (dealer should have recorded it in the service book's vehicle details)
Locking wheel nut key 8 digit number on the Honda Key Codecard ( should be in the main wallet's inside cover.)
If Honda are trying to confuse us all - they are doing a good job!
