Hi there. I purchased a used Honda Odyssey a few months ago.
Well, I had the radio on while I was outside and didn't notice that the side mirror defrost button was on. Needless to say, it wasn't long before my battery was completely dead.:eek:
So I read my manual and apparently I need to punch in a 5 digit code. I didn't receive that information when I purchased it so apparently I need to find the serial code on the radio to then call Honda and get the code.

I'm trying to find out how to remove the radio so that I can get this number but I can't find anything on the 'net that will actually show me how to do this.

Is there anyone who has gone through this dilemma?

Thank you very much.

You should have received a code card with the car (about the size of a credit card) with the 5 digit code on it. If you don't have it, Honda can look up the code using the VIN of the car (assuming the radio hasn't been swapped out for some reason). If that doesn't work, then you will have to pull out the radio to get the code using the serial number of the radio. Unfortunately, I've never taken one of those radios out, so I can't help you on the details of the removal process...

You will need to look for a white sticker that has a 5 digit code on top and a much longer one below it (one on bottom is the radio serial No.) The sticker is quite small about 3 inch long and 1 inch wide it can be in a number of different places - inside glove box, under glove box, on the door frames (can be seen with doors open) inside sunglasses holder, on the bottom of back door (can be seen when opened), underside of engine compartment fuse box lid, below steering wheel, (if not in any of those spots look anywhere else you think the first owner might have placed it). It should also be included with the paper work that you should have received when you purchased your vehicle (owners packet) if you cannot find the sticker you will need to have the radio's serial No. this can be obtained by one of two ways, 1st- is to hold down the 1 and 6 preset buttons at the same time while your radio is off then while holding these down power on the radio, if that does not work (in some vehicles it will not), you will need to remove your radio from the dash and find the serial No. listed on it, it will be on one of the sides i.e.. Top, bottom, back, or either side, once you have this No. you will need to call your local Honda dealer to get the code they will ask you for the radio's serial No. and most likely the Vin also, they might also want info to prove you are the registered owner of the vehicle but only if they no longer have your info from when you bought the vehicle or if it is not the dealer you bought it from. After you receive the 5 digit code you need to enter it when the radio says "code" on the lcd if it says error with any No. after it just enter first number of code because the first No. you enter when it says error will go in as the first digit of the code, if you entered the wrong code to many times the radio might have locked you out from entering any more codes if this is the case you will need to disconnect your battery terminals to reset the radio again wait 5-10 minutes before reconnecting them, and then proceed with entering your code. Also every radio has its own unique code there is no master code so you will have to go through one of these methods to reset your radio's anti-theft lock, there are many websites that say they will sell you the code via email if you give them the serial No. I do not recommend using these sites because many will give you a code that does not work, even if you think it is a legitimate web site because it uses PayPal as its payment method always remember PayPal only protects you when you are buying tangible products it does not protect you when it comes to anything electronically transferred such as a code sent to you via email so if the code does not work your money will most likely never be refunded, and the reason PayPal does not cover electronically transferred products is because people could scam the sites that deal in electronically transferred products because after receiving the right code they could claim it does not work and get there money back and therefor rip off the site. If you can not reset your radio after reading this you will need to take it into a dealer but that should not be necessary if you follow my directions. Hope this helps you all, I have went through this before and had a hard time finding the information needed so that is why I have compiled all the info I have on this problem, because it is horrible to not have radio in your car!
