Hello if you have the remote and the unlock key number
http://www.manualslib.com/manual/85987/Kenwood-Excelon-Kdc-X789.html#manual
Use the above link to the manual
If you don't have the remote you will need to get one as it is required to input the code
Need the code ask Kenwood ,the person you bought it from or take it to a local radio shack to get it read

SOURCE: can not find the code for my kenwood kdc-516s

Same problem, different rig. Bought a bronco with a Kenwood KDC 516s in it, Guy had put a new optima battery in it CODE_ _ _ _  appeared and he has no clue what the "code" is. I have no "remote" and no desire to buy a "remote" for a #$%@ car stereo. Is there any way for me to re-set the code w/out the expense of a remote or a fee from a tech?? the musically challenged, Brew
P.S. The owners manual under the "accessory" section  mentions the KDC x617/v-6017 remotes but fails to mention a remote for the 516s??

SOURCE: Kenwood KDC-3028 unlock code

TY TY TY..fixed this right on up. Only suggestion I could make is that a diagram of where the aforementioned buttons are. I did mine at night so the small words were hard to see. I just replaced my battery and cleaned off the cables connectors when this problem occurred. TY so much for this.

SOURCE: UNLOCK SECURITY CODE

for your kdc-mp528 will work whith code KCAR entered from the remote

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.

SOURCE: Kenwood KDC-MPV619. No remote. Need unlock code for deck.

I had the same problem with my kdc-mpv619. I had bought a new truck that didn't have a remote and the screen says enter code. You do need a remote to fix it, but what they don't tell you is a universal remote will work. I used my direct tv remote and looked up all the codes for kenwood.

The one that worked for me was 30337 (not sure if that would work for you).

1) The way I tested it was go to my stereo and I held down the display button + volume up button. (This should remove the - - - - sign but it will still say CODE).

2) Then you press the 5 button on the remote and if the screen says CODEK then you know the remote works.

(to switch from K to C to A to R press the (>>) button on the screen.

3) Enter the code KCAR (the display will say CODEKCAR)

4) Final Step is hold do the fast forward button (>>) on the screen.

It should work for you after that ;-)

You can try and call 1800-Kenwood and ask a tech, in the past we had to send them to a kenwood service center. Some authorized kenwood dealers have a universal code.

Tell friend to take it to the store where it was purchased, they have all the codes for equipment sold. If not an aftermarket unit, code is usually in the owners manual or hidden somewhere around the glove box.

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)
