I have lost the security code for my kenwood cd receiver. The model is KDC-MP4033S. Serial number is KE1202U0900623.


Hi,

Unfortunately Kenwood Radios can only be decoded on a bench and must be connected directly to specialist software. They cannot be decoded via serial alone. There is however a special procedure that can be used to bypass the security on these units using a master code 5227 (KCAR) which I will outline below.

Ulock code kdc-mp5028


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

hope this helps...

I just purchased a used motorhome that has a Kenwood KDC-MPV7019/MPV619 receiver. The previous owner did not provide the security code for the unit. How can I reset the code?


You will have to contact the previous owner to get the code otherwise you will have to buy a new stereo. There is a possibilty of being able to contact kenwood they might be able to reset it but it costs about 60 dollars to do so. I'm sorry..

Need security codes for kenwood KDC 4020


Common Kenwood Security Codes
Many Kenwood radios are configured with the same security codes:

KCAR - This seems to be a "backdoor" to some Kenwood models.
3051 - This is the security code which is printed in the manual of many Kenwood models.
1234 - This is a security code commonly chosen by Kenwood owners.
Entering Your Kenwood Security Code
If the car battery fails or is disconnected, the Kenwood will ask for the security code.

The procedure to enter your security code differs on various models of Kenwood car stereos. Here are three of the more common 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 until the "..." display disappears.
Enter the security code using your Kenwood remote.
Type 2
Press and hold the "Auto" button and "Track up" (next track button on the right) on the face of radio at the same time until the four dash lines disappear.
Enter the security code using your Kenwood remote.
Type 3: Model# DPX-4020 and DPX-4030
Press and hold the 1 then the 6 preset keys until the display shows the letter 'C'.
Enter the security code using your Kenwood remote.
Entering Letters on your Kenwood Remote
To enter a letter using your Kenwood remote, press a button once for the first letter, twice for the second letter, and three times for the third letter -- then press the Track Up or Next Track key to send the letter.

To send the letter 'A', press the 2 key once and then press the Track Up key. To send the letter 'B', press the 2 key twice and then press the Track up key.

Finally, when you are done entering all of the letters, press and hold the Track Up button for 3 seconds.

The key sequence to enter the security code KCAR is:

5
5
Track Up
2
2
2
Track Up
2
Track Up
7
7
Track Up
Your Kenwood should then enter tuner mode.

A Security Code Bug in some Kenwoods
There is a reported bug in the security code handling of some Kenwood stereos. In models with thie bug, the security code is stored incorrectly. The workaround is to enter the wrong security code.

In models with this bug, you have to decrement the third character of the security code by one. If your security code was 1111, you would enter your security code as 1101. If your security code was 9999, you would enter 9989.

i hope this works for you.

Great!

There is a trick we used to use in the workshop to bypass the code using a remote control when working on the head unit on the bench. Go here for a procedure on how to do it. A FixYa rating is a great reward for solving this for you. Cheers

My work van stereo is now locked and needs a code after I had to change the van Do you know it or who I could ask who might know what to do It is a Kenwood and on the front panel it has KDC-5016


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.

I have a Kenwood kdc mp828. I disconnected my battery cable and now can not remember my security code. I need to reset the unit so I can again listen to my stereo.


I read a blog on your site about Kenwood stereo's. I used that information to unlock my stereo security code. Albiet, I did have to figure out a bit of the code needed myself. I am again able to listen to music on my stereo.
