Depends on what the error code is.
Leave the radio on for 1 hour and it will reset and then accept the 5 digit security code.
It means there was an error inputting the codes to unlock the radio. If the radio locks just leave it on and in about 1 hour of use it will unlock and allow you to try again.
In order to clear the radio code "ERR-3" in a Honda Accord, you simply open the hood and remove the radio fuse (there are two of them so remove the one closest to the car window) for about 10-15 seconds, put it back in and close the box, crank up the car and enter the vehicles radio code(this is usually located on a white card when you first purchase the vehicle or possibly in your glove compartment in the manual), make sure you enter the code correctly, and then the error will be removed and you can start playing music in your car! If you do not have the code then go to the Honda Owners website and register your Accord. After you register it you can get the code for free.
