It is on protected mode when i hit the reset button

Hit the reset button. It should be behind the headset. Using a small pin or needle just press and hold it for 3 seconds.
Usually that will do that trick.

There is a reset button on the front of the face plate buy the buttons for changeing your radio sations.It is right beside the last button on the right side of the face plate.Take a pin or something with a point on it, To push the reset button in with, Hold it for a couple of seconds,Then it will come back on.There is no code to unlock it, Only if you put a code into it .(But) before you do this (Check) That no speaker (Wires) Come off from the (Speakers) or from the deck some where. If a wire come off make shure to put it back on (Properly) Before you reset it. It can allso go into the protect mode if your car is hit in a (Accident)

My kenwood is stuck completely in protect mode. I ve everything listed and it wont come out of it. So should i assume the unit has gone bad?

Do you mean into the unprotected mode?, if so

Turning OFF Protect mode in a Riso MZ 790u (and other models I'm sure).

1. Go to Admin Tab on the main console screen and scroll to the "Protect" button.
2. Select (press) the "Protect" button on the screen; printer will go through a reset function (takes about 3-5 seconds).
3. After printer is finished "resetting", pull out one of the master disposal boxes (doesn't matter which one).
4. Press the "Protect" button again.
5. the screen should say "Protect = Off"
6. You're done and your machine should be un-locked now.

First of all , your Kenwood shows only Protect on the display when your speakerwires are conflicting with each other , but when you cannot find the problem there....

disconnect them one by one to see wich speaker in your car is conflicting (shortcuts).

Replace that speaker and your kenwood will work just fine.

I had the same problem here with a brand new Clarion speaker .

The reset buttong is usally behind the faceplate.

One thing that may have happened is that you somehow accidentally entered security mode. This is similar to OEM units that have a 4 or 5 digit code. On the MP435U, you can reset the unit by pressing and holding the small reset button just under and to the right of the main knob. This will, unfortunately, wipe all your setting so you will have to set the unit up all over again. While you are setting it up, set the security code to something you will remember so you can get by this in the future without resetting the whole unit. In stanby mode hit the menu button. The unit will display CODE SET. Hit Enter. Using the buttons and knob, enter your code. You will have to do this twice and then the unit will confirm with APPROVED.

Try checking all of your connections something may have come loose, usually its a speaker connection that may have come loose and come in contact with a piece of the car's chassis or a metal part. This will cause the 512 to go into Protect mode. When you fix this hit the reset button.

I just picked up this watch.  Setting it is easy.  Hold down the button marked "RESET" (lower right) until the numbers start blinking.  Hit the "MODE" button (lower left) until the the settings you want to change are blinking.  Hit the "ST/STP" button (upper right) to change that setting.  Keep on hitting these two buttons until the settings are as you would like them.  Hit "RESET" button to finish.  So, to change just the day, I would hold down "RESET," hit "MODE" four times, hit "ST/STP" until the date is correct, hit "RESET" to save.  

Kenwood KDC-MP436U Pressed incorrect code to many times and now protected is displayed on screen. I have lost my code. Tried reset button and disconnecting all the wires. I am so annoyed that they have this code, though happy that I am not the only one that has lost it!! :) PLEASE HELP ME Cassandra
