you need to have the code for the radio to unlock the radio, without the code I'm not sure you can unlock it without sending it to a shop who can rebuild/refurbish it. If you have the code, push the band button until it says "code" you then enter the 4 digit number and the radio should unlock. If it doesn't you haven't entered the correct code. Good Luck
