Question about Car Audio Receivers
Last yr, my husband went to an auction and bought me a kenwood car stereo. Because of the wriing harness, we did not use it for my suv. Now, his stereo died and he was going to use it in his. BUT... he found out that you needed a security code??? Is there anyway to retrieve this from the stereo itself? There is no way we would ever be able to track down the previous owner. It is a KDC-4022
Any help or suggestions you could give us would be greatly appreciated.

I found this on a forum and some people got it to work, If you do not have the remote I do not know any more about what to do for you.
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

Many Kenwood radios are configured with the same security codes:
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.
