DNX7100 Security Code Password

Unistalled the  unit out of my old vehicle and installed into my new car. Of course when power is lost it goes into anti theft mode. Well when I typed in my original password the unit is still locked out. I tried several times. Also 0000,1111,1234, and the Kenwood 3051. I called Kenwood and faxed  them my receipt of ownership and they told me to type KCAR, but their instructions on typing KCAR in the unit was confusing and cannot figure out. Anyone have any ideas?

    I purchased a DNX7100 from a flea market, and I thought I was purchasing a new unit, but when I got home I realized it was used. I went back to the flea market the following weekend and the guy wasn't there. Now I have a unit that I can't use because i don't have a password. Do anyone now how i can reset the passcode? Please help!

While code request mode,point the remote control to the unit and enter this code 55222277or 552222777(depending the remote contro you are using)(try to press the numbers that faster you can) that is way you type KCAR from the remote control.
you will not see any change on the screen while you entering the number,only when you enter the last number the unit will go to standby mode.
if you make a mistake,reset the unit and start all over again.

let me know if works
thank you

    HOW I UNLOCKED MY KENWOOD CAR STEREO DPX-8070MJ
    from www.technologz.com
    I have a Kenwood DPX-8070MJ Radio in my car. The battery on my car was changed and the radio was now requesting a Security code ( CODE****). I tried all tricks but in vain. Eventually i managed to unlock it.

    Here are the steps of unlocking a DPX-8070MJ radio player:


    (1) Press and hold the 1 and then the 6 preset key. There are 6 preset keys or buttons on the face my radio on the left side. The radio will display a "C" just after the "CODE****"


    (2) You now need to enter the code "KCAR" using a Kenwood remote control (The remote control for my radio is RC-600J). Point your remote towards the radio

    (3) Press Numeric Key "1" until the letter 'K' is displayed

    (4) Press Numeric Key "2" until the letter 'C' is displayed

    (5) Press Numeric Key "3" until the letter 'A' is displayed

    (6) Press Numeric Key "4" until the letter 'R' is displayed

    (7) Press "Ent" button on your radio and YOUR RADIO WILL BE WORKING AGAIN

    Deck was brand new when it was installed in 2002. Emanuel..I took your advice and pit in 55222277 with the remote, not good. The deck cycled and shut off. I turned it back in and put the screen back in. Tried to start over but to my surprise the screen would not come back out. I hit the reset button to try and start over and nothing, it just keeps cutting off. Prior to posting on this site I did call Kenwood, they told me to go to an authorized dealer, I went to two they told me about here in St. Paul Mn. Mach 1 and best buy, they both told me to call Kenwood. Oh boy...any suggestions...

You call Kenwood, and get the info for the closest national service center, they will tell you how much ($45 for me plus S&H), you ship the whole unit to them, and they send it back unlocked. Major bummer for me, I bought my car used, didn't get the code. I understand the need for security, but all this process does is shift some of the profit away from theives and back into Kenwood's pocket.

Lost code for sony cdx-m800


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 Sony dealer.
Hope this helps, Good luck with it.

NO PASSWORD


When at the password screen, use the remote and spell out KCAR like you would on your mobile phone (55 222 2 777). That should unlock it.

No Sound


Id call you local stereo shop. I changed the head unit out in my old acura legend and had the same problem. You need to buy a special harness for the bose. Each speaker had its own amp, so i just rip it off and wired the speaker direct and trashed the amps. Now this was an older car and speakers were almost shot so no biggie. I would not recommend you doing that on and 04. Just call your local stereo shop and they should hook you up.

It only goes down half way. You have to gently push it down the rest of the way to expose the SD card slot.
