SOURCE: i lost my security code for my audiobahn A3751 can

The original code you got with the unit will always override one that you entered. As long as you have the product card (in the information that came with the unit) you should be all right. If you lost that card you can try resetting the unit, but I think the code is designed to still be in effect. Let me know, I can do somemore digging..... Do you still have the owners manual (google it and you can download it free)

My Kenwood car radio needs a code ,model for my car radio is. Dpx7021mpg


A number of Kenwood stereos are sold which use the same security code. Some of the most commonly encountered codes are:
1234 - Not a factory default, but a commonly found security code when attempting to figure out the code for a Kenwood radio purchased second or third-hand.
3051 - Security code included in a number of Kenwood radio manuals.
KCAR - A common Kenwood model security code that has been found to work across a number of models of the stereo

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.
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.
Finding the Kenwood Security Code

There are backdoor codes for each Kenwood car stereo, based upon the model and the serial numbers.

These backdoor codes are closely held secrets. Outfits like Car Audio Accessories UK will sell you the code for your radio for £20.
Sending your RadioBack to Kenwood

If all else fails, you can send your stereo back to Kenwood to have the security code reset.

Do you have another solution for audiobahn lost security code help me please thank you


You can use the original code (came with the product card) to override any code you entered. If you have lost the original code from the factory you could probably provide proof of purchase to the manufacturer along w/ the serial number and they may be able to give you the code. If not try resetting the system, but I dont think that will work. Hope this helps.

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.

Code audiobahm a3751


You can use the factory code that came with the unit (should be written on the product card which was probably in with the literature you received with the unit) to override any code you have entered. If you have lost this original card you can try emailing the serial number to the manufacturer along with a proof of purchase and serial # and they should be able to provide you with the original code. You can try resetting the player (disconnecting battery and using the reset button on the unit), but I think the codes were designed to not be "beat" like this. FYI, if you dont have the owner's manual anymore a quick google search provided me with a lovely free PDF.
Hope this helps
