What year and model is your Honda?
That year model should only require a 4 digit code. Can you try dropping the first or last digit to see if it will work? Like 5313 or 1531?
Try to get the serial number again to make sure it is correct, it should be 8 digits and it looks like you have 9.
If you have the Error message you will need to disconnect the battery to get the error to clear so you can try entering the code again.
After you disconnect the battery for about 1 minute and then reconnect it the radio should show COdE on the display if you try to turn it on.
Also, check your glovebox for stickers with a 4 digit number on them. A lot of dealers will put the unlock code in there somewhere.
Ok, that looks like a good serial number. Do you have the Vin? I could check what honda shows as the correct unlock code.
If you don't want to remove the battery you could remove the #17 fuse from the under hood fuse box.
The fuse box is in the engine compartment on the driver's side fender. The lid will have a diagram that shows which fuse is #17. It should be labeled "audio" or "sound", or maybe "radio".
I'm sorry for the delay. Just Answer was acting up.
Turn the engine off before pulling the fuse. After you pull the fuse for about 1 minute reinstall it and then get back in the car and turn the key to the on position. The radio may display COdE immediately once the key is turned on, but most likely you will have to turn it on first. Once you turn it on press the numbers 1,5,3,1,3 (I looked up the code and it is correct- not sure why my honda manual says it should be 4 digits) one at a time. On the last digit (3) it should unlock and start working normally.
Here is a video a guy make on YouTube showing how it's done. The radio may not be exactly the same but it should be similar enough to see how it's done:
