Page 13 says it is activated by the user. It tells you to treasure the code. Ask the last user. Take it to a Kenwood Service centre. Try a reset as shown on Page 3 of the manual.

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.

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.

I have a kdc mp538u which turn off when I change of battery and when I turn it on again was locked and I didn't configure any passwords, which is the default one for this model, I will really apprciate...


You can enter a 4-digit security code as an option after purchase of the unit. If you do so, make sure it is noted down somewhere. If you did select a code (or the previous owner has done so) this must be used when the unit is removed from the vehicle, or the constant power source is disconnected from the unit. When constant power is restored to the unit, the security code must be entered before the unit becomes operational. If the code is lost or forgotten I am afraid the unit has to be re-coded by a Kenwood dealer.
Hope this helps, Good luck with it.
However here is a link for a tip as posted by robotek, therefore all credit should go to him, Regards.

Kenwood KDC-MP538U does not save settings like time and date


I have had the same problem, my problem was that i accidentaly hooked up the constant wire to the switched, and the switched to the constant, causing it to turn off completely, resetting everything. So if this is the problem then just switch the wires in the back of thew head unit, should be the fatter yellow wire, and the fatter red wire
hope this helps

Security code Lockout


I had a similar issue with a head unit in a newer Volkswagen. There was an unlock code burried in the vehicle's owners's manual.

Since your stero is an aftermarket model, I would bet the unlock code is in the manual for the head unit.
