The radio is lock needs code on my 03 Pilot. I need code to unlock my 03 Pilot radio.

Replace the radio or use workshop manual 2 unlock the code

There is a small electric motor inside the actuator assembly that has probably "burned out". Same problem with my 03 pilot. The remote would not lock the other doors or arm the security system unless you physically locked the driver's side door. Eventually my passenger side burned out as well. Fixed it myself pretty easily. Cheap fix too. works like new now. http://www.ebay.com/itm/120935451126?var=420082237231&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

You will have to get the code from a local Honda automotive dealership in your area . You will need the display code or serial number and proof of ownership for the vehicle before they will give you the proper unlock code for your radio .

Sadly:
There is only 2 options.
1. Your radio code is in your paperwork for your car (Its on a hard plastic card) Find it.
2. Take your registration to Vin and Ser Number for your radio to your local dealer.
These codes are a guarded secret and no one code fits all.
Hope this tip helps guide you in the correct direction to solve this problem.

the only way to unlock the radio is taking it to a dealer you need to unlock it with a scan tool
hope this helps

the dealer is the only one that can unlock a locked radio, they will need to remove the radio, get a "code" off of the sticker on the back of it, and then call the dealers unlock assistance number to get an unlock code. it cant be done with out the dealer. im sorry :(

dealerships are usually very helpful with pulling the codes and unlocking it. Catch them on a good day and they may do if for free. if not they usually charged about $60..

found this online maybe it will work for you

I bought an 04 Odyssey EX as a cerified pre-owned a few days back. It has an anti theft radio. The dealership, in its infinite wisdom, put in a new battery but did not back up enough power to keep the code in the radio and then could not find the code! Despite their promises to the contrary they did not call to report my fix. So I called the service department instead. Good move.
It turns out first that the 5 digit code is on a sticker found on the side of the glove compartment. Usually on the outside left when you open it up. There are two numbers there - you want the five digit one.
Now here's the key - the salesman no doubt has tried a bunch of random numbers or ones he is getting from the wrong source. Once ten attempts are made without the correct code being entered the system locks itself up and will not accept any code. This is to keep someone crazy enough to keep trying random numbers, such as a salesman or a thief (I'll be good...) from eventually finding the right sequence.
There are two ways of releasing the block. The first is to run the radio for an hour. No sound will come out but once it has been on for an hour it will unlock itself and you can put in the code. If you are like me the idea of running around for an hour with music is a non-starter so I went with the quicker solution - disconnect the negative battery cable for about a minute and then reconnect. You now can enter the code and all will be well. Well, except for the fact that now you have to reset your clock as well but if you will go through that much to get the radio back setting the clock is probably withing your area of expertise.

In the newer Honda's there is a lock code on the radios when they lose power the code kicks in to prevent theft the reset code should be in your owners manual if it isn't call your locale Honda dealer.

First open you glove box and look on the sides of the glove box. Look on all sides. Then check your owners manuel in secruity codes section. If the tech who did the PDI On the car did it properly you should have the code written in then and a sticker on the outside of your glove box.

If not then call the dealer and they should be able to look it using you VIN number,
