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 the "Auto" button and "Track up" 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 need to obtain a manual for the Kenwood KDCMP 4028 car radio with CD. I had one put into my car,but don't know anything about it. My Mechanic found one for me but he didn't have a manual.


Crutchfield has the manual for the Kenwood KDC-MP4028 on the product details page: http://www.crutchfield.com/S-GEgeczn1k6L/p_113MP4028/Kenwood-KDC-MP4028.html . Choose the Details tab and scroll down to the What's in the box section. The direct link to the manual is http://pdf.crutchfieldonline.com/ImageBank/v20050530080800/Manuals/113/113KDC3028.PDF . Kenwood also has the manual in their support section. The direct link is http://manual.kenwood.com/files/B64-2949-00.pdf .

I hope this helps.

(You'll need Adobe Reader or a similar program to access the manual. If you don't have your own printer, you can probably get the document printed at any print shop after putting the file on a USB drive.)

Kenwood kdc mp235 security code


When you disconnect your battery and then reconnect it again, it disables the radio. This is an anti-theft protection for your car radio.
The enable your radio the activation code is in your vehicle owner's manual. If you do not have this code you need to go to your vehicle manufacturer's service centre and get them to enter this code for you.

REPLACED REMPOTE ON KDC-MP4028 AND STILL CANT ENTER SECURITY CODE HOW DO I KNOW THE REMOTE EVEN WORKS


Radio code is specific for each and every car. It is specific like anti theft code.

You can get it by providing your VIN# and registration details in authorised dealership.
Nobody else can provide you. If anybody can provide you that , then there is no meaning of security for your car..

I have a Kenwood KDC-MP 4028 car stereo that I need to unlock the code.


Unfortunately Kenwood codes are only available from the Main Dealer or by using a Radio Decoding Service who will connect a laptop to read the working code inside your radio`s memory chip (EEPROM)

I own a mitsubishi eclipse gt 2000 i had to disconnect the battery now the stereo is asking for a code. does anyone know the code?


for stock radio codes, check your owners manual front page or towards the back, normally the code will be written there, if it is not a stock radio call the manufacture and tell them the serial number and model number they can get you a generic code for it, or tell you what to press to reset it. hope this helps
