As far as I nkow, you need to contact Kenwood with the radio serial number to get the unlock code. In the past, they would not give it to you without giving them a special code from a card that came inside the package. You can always try though, give them a call, the number is on their website.
If it's asking for a code then someone phisically put it in there. The unit comes unlocked from the factory. the only way to unlock it now is to get whoever put the code in there to unlock it or give you the code.
try using the code "kcar" on your remote press the numbers that correspond to the letters . This code is used for most basic kenwood, make sure you have valid remote because sometimes the stereos do not allow you input manually from the face plate
