There are allot of possible places your code can be within your car from manufacturer, For instance, Inside the glove compartment on the left or right side there coule be a white sticker with the six digit code on there, or.. in your trunk in the inside of the lid. Also (where i found mine) where your air conditioning (in cabin) filter is located. (behind the glove compartment door) there should be a white sticker there. either way the code you can get it from honda (the website) by registering your VIN identification Number. Or instead of showing up to honda, just call them and they will gladly give you the code for free.
Hope this helped.
