I recently changed the battery on my van and now my kenwood kdcw7531 is asking for a code which i dont have

Its usually on top of the radio

it is an anti theft device that activates when power to the radio is cut
the code would have come with the new radio or is in the user manual for the radio

You can enter a 4-digit security code which must be used when the unit is removed from the vehicle, or the constant power source is disconnected from the unit. When constant power is restored to the unit, the security code must be entered before the unit becomes operational.
If the code is lost or forgotten I am afraid the unit has to be re-coded by a Kenwood dealer.
Good luck with it.

The only way to get the code is to call Kenwood and give them the serial #. Here is there #

LOOK FOR RESET BUTTON, OR UNPLUG THE LUG FROM THE POWER(12V) AND REPLUG IT, ...OR IF ANY CMOS BATTERY IS FOUND INSIDE, MOVE IT AND REPLACE IT...HOPE IT WORKS

I had a problem as well with my KDC-MP6025 after I changed my car's battery. I called Kenwood four times asking about why my security code wouldn't take, and on the fourth call the tech said some random 2004 models (definately the MP6025, and probably it's sister receivers the KDC-X678 and the MP625) the decks firmware subtracts one from the 3rd digit if the sequence, i.e., if you set it for code 1234, you'd have to enter 1224. Since I sent Kenwood my product registration, it would have been nice for them to tell me this. I would have been BS if I had found out after if I had kept my $60 appointment to get the code cracked at the authorized repair place Kenwood recommended.

All original car radios have their own unique security codes.

Assuming your radio is the original for this vehicle you simply take your vehicle ownership and registration papers to a Ford workshop they can get the code from the Ford computer network on the spot.

If the code does not work then it means that this radio is not the original for your car as it would have been replaced with them radio model.

If this Kenwood is an after vehicle purchase, you may need to contact Kenwood Car Audio.
Or get Kenwood's contact details through your local car audio dealer.

here is a link with the how-to and a universal code, it is worth a shot.
