I need unlock code for my kdc-mp2035 kenwood stereo

Disconnect the power, check your speaker wire connections behind the stereo and at the speakers. Reconnect the power and test.

You can enter a 4-digit security code as an option after purchase of the unit. If you do so, make sure it is noted down somewhere. If you did select a code (or the previous owner has done so) this 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.
Hope this helps, Good luck with it.

You cannot override the code, you will have to take it to the nearest service dealer.
I'd appreciate if you rate this 4 thumbs if I had helped you. If I couldn't help you please rate accordingly.

Sorry....KENWOOD codes are only available from the Main Dealer or a Radio Decoding Service

Here is a link to the owner's manual for the stereo:

BUENAS NOCHES

TENGO EL EQUIPO PERO PERDI EL MANUAL Y NO HE PODIDO CUADRAR EL RELOJ Y PROGRAMAR OTRAS EMISORAS

MIL GRACIAS

My hunch is that the fuses blew. When you cut all three at once you shorted the battery to ground and most likely blew out the fuses. Check the fuses and let me know. That is my best guess. Good luck
