You can download the manual from here;
http://inform3.kenwoodusa.com/manuals/KDCMP228.pdf

page 18 says that the code can be set to anything you like, it also suggests that the security code function can be enabled, (suggesting to me that you are able to reset the unit)

I would try taking the unit apart and searching for a battery. it may be as simple as resetting a bios on a computer motherboard.
if you have not done this before the idea is to remove the battey for around 30 seconds whilst the unit is removed from an external power supply, then replacing the battery and then powering up the unit again then see if the security code has been removed.

it's just an idea but unless someone else posts a better soloution it may be worth a go.

Ok, the instructions for entering the code are in the manual, I hope you have it, sometimes the code is also included inside the user manual. If you don't have either, you can contact kenwood to get it reset. 
There should be a expert or two on this website who might be able to unlock it for you even if you have lost the code.

Anyone have the code to reset this radio. battery went dead now the radio will not come on ?


Try checking your fuses. If the radio doesn't come on a code is not going to do any good. As far as I know these radios don't require codes anyway.

Battery went flat so need radio code for renault megane


With the car, comes a plastic "infocard" with the radio and alarm codes. If you lost the card or didn't receive it with the purchase, you can ask for the code to the radio manufacturer, they'll ask you the serial number of the radio and the car and they'll send you the code.

Sounds like either the fuse has gone in the fuse panel forthe in car audio or that you need to get an activation code for your radio.

BATTERY WENT DEAD AND RADIO IS IN LOC MODE CAN YOU HELP ME CHEVY S10 PICKUP 2000


YOU SHOULD HAVE THE LOCK CODE ON A SMALL CARD THAT CAME WITH THE TRUCK POSSIBLY WITH OWNERS MANUAL OR IN YOUR GLOVEBOX. IF NOT YOU MUST REMOVE THE RADIO AND RETRIEVE THE NUMBERS ON THE BACK OF THE UNIT AND CALL A CHEVY DEALER TO GET THE CORRECT CODE TO UNLOCK THE FUNCTIONS.

Ford mondeo radio says locked


HI if you have the correct code, then pushing and holding the 6 button will give you one more attempt, if you enter the wrong code again, may as well put the radio in the bin .
make sure the code is correct!!

Entering Code for Car Stereo


Turn on the ignition, turn the radio off fully. (by preeing the volume wheel knob) press AS or the button that turns it to CD mode (should have circle on button)keep it pressed and turn radio on. wait for a beep then it should be somthing like:

10----------- (10 being the number of tries left)
use buttons 1,2,3 & 4 to input your code. press the button more than once for it to rise higher.

Hope this helped.
BTW i got the same problem with my dads astra. but i dont even know the code :(
