KENWOOD SECURITY CODE CLEAR procedure


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

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.

What is EC code in kenwood a.c ?


  1. If your car battery died, your Kenwood stereo will ask you for a code. There are various ways to enter the security code; this depends on the model of your Kenwood stereo.
  2. Look in your manual and see what the security code is for your particular Kenwood stereo. There are common security codes on many Kenwood stereos. Kenwood claims security, but its stereos have many of the same security codes. Here are three common security codes: 1-2-3-4 (a code many Kenwood owners use), 3-0-5-1 (a common security code in Kenwood manuals) and KCAR (works on some Kenwood stereo models). You should have a code within the pages of your manual. Luckily, many Kenwood stereos have the same security codes.
  3. Enter the security code into your Kenwood radio. Method #1: During the code request mode, while holding the DISP key depressed, press and hold the "Volume UP" or "DOWN" key for three seconds until the " ... " display disappears. Enter the security code using your Kenwood remote. Method #2: Press the "Auto" and "Track Up" button on the face of radio at the same time until the four dash lines disappear. Enter the security code using your Kenwood remote. Method #3: Press and hold the "One" then the "Six" preset keys until the display shows the letter "C." Enter the security code using your Kenwood remote.
  4. Tips:
  • If you did not have your manual, try the most common codes for Kenwood stereos. If those codes don't work, you can also buy your Kenwood stereo code online. There are places online that will sell you the security code to your Kenwood stereo.
  • Keep your security code and this information in a safe place.

Newer Kenwood models have the security information stored in non magnetic flash memory.
Once the code is set, it cannot be retrieved by a "backdoor method".
Proof of ownership is required. You can take the radio in to any AUTHORIZED Kenwood retailer - and in 10 minutes - they can have your radio reset for you.
If all else fails, you can send your stereo back to Kenwood to have the security code reset. They require proof of purchase.

This can be a receipt, or a used car invoice.

This unit came in a car I bought for my daughter but never worked, was told I needed a code to restore to working order. Any help or codes out there? Kenwood KDC-X711 Thanks, Gene W.


Kenwood auth service tech can do it if you can convice him it's not stolen. Owner has put a security code in it. If the stereo is removed or the battery has been disconnected you can't use it if you don't know the security code. Anti theft works great. He will check seial number with database.

I forgot my code for my kenwood car stereo


You didn't write them down, or remember 4 numbers that mean something to you. And now the receiver won't operate with out the correct security code. If you can't remember you need to have a Kenwood Service Tech reset the code. He'll be glad to do it for you.
