how do i imput the anti-theft code on my 2003 honda CRV?

 

It should ask for the code then use the 1234 buttons(if im not mistaken) to put in the number. Its like texting on a cell phone. say your code is 2048:

You press the 1 button untill it goes to 2
and so on for each number in the code. Just press the buttons on the radio untill you see numbers instead of code.
