I have forgotten the security code of kenwood dpx 9100mji

SOURCE: 4 digit security code reset

Here is the link for the user manual if you need it; http://inform2.kenwoodusa.com/manuals/KDCMP228.pdf Page 5 shows the reset button, page 19 shows all the security code procedures which have to be followed even after a reset. This site has a few partial methods which might be worth trying for your player but unfortunately no complete solution; http://forum.ecoustics.com/bbs/messages/4/312069.html Sorry but I think it has to be a dealer - if it was so easy there would be no point having security codes at all - Kenwood says; "How do I reset my security code? If you do not know the security code for your unit, you will need to take the unit to a Kenwood authorized service center to have it decoded. The code feature can only be activated when the code has been entered twice, so it isn't accidentally activated. The service center will often require you to provide a proof of purchase as this feature is designed for theft prevention and the proof of purchase will ensure you are the rightful owner of the product. You can locate the nearest service center in your area here, or by calling (800) KENWOOD. Though we try to locate service facilities in local areas for our customers, at times consumers may be required to ship their product to the facility for repair. Once you have had your code reset, please make a note of the code and keep it in a safe place away from your vehicle." Hope this helps - sorry if bad news :)

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.
