Need kenwood code reset procedure - Kenwood DNX5120 DVD Navigation System GPS Receiver

call kenwood tech support

The only factory default code for these units is "5227" or KCAR. After entering this code, you would press the track forward or "FF" button. Perform this procedure using the remote. If this does not work, then you need to send the unit to Kenwood along with proof of purchase for them to factory unlock it.

Here is some good info from another site (as linked below):http://www.tech-faq.com/how-to-reset-a-kenwood-security-code.html


If these methods don't work you would have to send the stereo back to Kenwood to be reset.

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.

Your code number is XXXX (KCAR)

* Press numeric key "5" ( 2 times ) and press the Track UP/Next Track key
* Press numeric key "2" ( 3 times ) and press the Track UP/Next Track key
* Press numeric key "2" ( 1 time ) and press the Track UP/Next Track key
* Press numeric key "7" ( 2 times ) and press the Track UP/Next Track key

i am also pretty certain that you will need to use the remote control to input your code.

If this master reset does not work, the unit will need to be sent to kenwood with proof of purchase for them to reset it. ................... in saying that I am yet to hear of this procedure not working.

hope i helped, and please dont forget to rate my solution. :-)

cheers

Newer Kenwood models have the security information stored in non magnetic flash memory.
Once the code is set, it cannot be retrieved by a "backdoor method".
Proof of ownership is required. You can take the radio in to any AUTHORIZED Kenwood retailer - and in 10 minutes - they can have your radio reset for you.
If all else fails, you can send your stereo back to Kenwood to have the security code reset. They require proof of purchase.

This can be a receipt, or a used car invoice.

The code on Kenwoods is user programmable and is not set from the factory. You will have to reset the unit and go through the procedure to set a personal code.

● How to clear the Security Code
In adjusting K/R destination units, if the unit starts up with
Security ON, the Security Code can be cleared in the following
manner. (Other than in Test Mode)
1) In the e Security ON condition, after resetting or turning
power ON after backup OFF, then the session starts with
Security Code Input screen.
2) With the attached remote control in the Audio SW selected
condition, input the code with the following procedure.
Procedure 1: “K” input (Press Tenkey [5] 2 times)
Procedure 2: “C” input (Press Tenkey [2] 3 times)
Procedure 3: “A” input (Press Tenkey [2] once)
Procedure 4: “Q” input (Press Tenkey [7] 2 times)
Note: If a remote controller other than the attached is

from Procedure 1.

Security Code is cleared.

No such code.

i hope this works for you.

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 :)
