Kenwood MP4029 4 code reset


I had my Car CD Player Kenwood KDC-MP4029 serial number KE1111T0900507 taken out of my old Toyota Corolla and placed into Honda Prelude. The CD player asks for 4 digit code and I don’t know the code.


Could you please help me in getting my CD player to work again on my Honda Prelude?

Your radio will require one of the following procedures.

Type 1
During the code request mode, while holding the DISP key depressed, press and hold the Volume UP or DOWN key for 3 seconds (so that “…” disappears).
Then using your remote enter your code.

Type 2
Press the "Auto" button and "Track up" on face of radio at the same time. The four dash lines ( . . . . ) should "disappear".

Then using your remote enter your code.

Type 3
Model# DPX-4020 and DPX-4030
Press and hold the 1 then the 6 preset key (preset keys are the buttons on face of radio for storing you "favorite" radio stations). "C" should display.
Then using your remote, enter your code.

Enter your number from the remote control unit. Your code number is 5227 (KCAR)

* Press numeric key “5” ( 2 times ) and press the Track UP/Next Track key
* Press numeric key “2” ( 3 times ) and press the Track UP/Next Track key
* Press numeric key “2” ( 1 time ) and press the Track UP/Next Track key
* Press numeric key “7” ( 2 times ) and press the Track UP/Next Track key

The security is canceled and the set enters the TUNER mode!

Different or additional harness needed to install a Kenwood kdc 255u radio/cd player in a 2005 Scion XB?

Hi there,

YES.... to prevent cutting of any factory wiring (this use to be the old install method and requires much more time and expense) and potential electrical fires, you can now buy quite cheaply, what is called a Radio adapter harness.

As you wish to install a Kenwood radio to your Toyota Scion, simply buy an adapter loom which has a 2005 Toyota Plug on one end, with a Kenwood plug on the other (this essentially replaces the wiring loom that came with your Kenwood unit).

So, it's that easy .... Plug and Play.

And... if you sell your Toyota and wish to put your old Toyota radio back in, the original radio just plugs back in. PRESTO !

Hope this helps..

Code for my kenwood

It don't work like that. Each individual head unit has a seperate PIN code. Best bet is to get the serial number from your unit. Located on top or back of it, and call Kenwood direct with the serial the serial number, they have all codes on file, they can help. Here are the numbers

Kenwood Australia - 1800 126 659
USA - 1-800-KENWOOD (536-9663

If not either of them, go to their site
