If you have the code ok, most radios will display CODE---- press button 1 and enter first number by repeatedly pressing 1 button,the number will appear on screen,press button 2 for second number and so on,then press 5 and it should come on,if it doesn't work first time and you entered it right relist your question,to many tries will lock your radio and it is a dealers job then.
