I have this problem almost everytime I have to do it.  It's such a rare occasion.  If I remember correctly, just press and hold the key that moves you to the next number... the >>| key, I believe.  After a couple seconds it'll beep & open up (provided you have the correct code).

If you are using an amplifier, make sure you are using the blue/white wire to turn it on. The blue wire is power antenna remote turn on and turns off when leaving tuner mode.

It sounds like the contacts are getting weak or the contacts are dirty... Take off the face and clean the contacts with alcohol. If that dosen't help then take a paper clip and gently bend the pins up. Be careful not to break the pins.

Red is usually 12v switched and yellow is constant.I have done many brands and that is the norm but I have not done Kenwoods.Here is a link though.I couldn't find yours but did find a 435.Makers usually stick with the same colors year after year so it should not be an issue.The print is small and i couldn't find a way to largen it.

Good luck! Greg

Apparently, this auxiliary input only works for a Kenwood CD changer or a sirius radio connection. At least that is my conclusion after finding the same problem. Let me know if you figured anything out on this.

if it was a reputable company who installed it take it back to them cause they should have a lifetime warranty on all installs

Sorry....KENWOOD codes are only available from the Main Dealer or a Radio Decoding Service

you'll need your vin # as well as the radio serial and part # (which will be on the radio) handy then call 1888mitsu2008 they will give you your code free of charge

you need a kenwood remote and search the web.

First make sure that the code has not been noted somewhere within the car (underneath the ash tray, glove box , rear of sun visor etc) 

To see if your code is available here for free then the radio will have to be removed from the dashboard (and if you are lucky, someone may have written the code on the casing ) .

If not then POST ANOTHER QUESTION

quoting the radio MAKE+MODEL plus ALL the LETTERS+NUMBERS on ANY LABELS ,BARCODES or STAMPED IN THE METAL CASING

note: Unfortunately not all radios can be decoded using the Serial Number 

If not then try your Main Dealer ...........or take it into a Decode Service who will plug in a laptop to read/recode the memory chip (EEPROM). This takes a few minutes and shouldn`t be too expensive 

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.
