"Protect" isn't for security on a Kenwood; it's caused by a problem with the speaker output. There may be a defect in the CD player, or you may have a blown speaker or a shorted speaker wire in the vehicle. Try disconnecting all the speakers and see if the unit still shows "protect" when you turn it on. If it still shows the "protect" message with no speakers connected, the unit needs to be serviced; if not, re-connect the speakers one at a time until you find out which one is causing the problem.

I had "protect" flashing on my kenwood KDC-MP232 also. I fixed the speaker wire problem but I couldn't get the "protect" message to reset. I had to remove the unit from the dash and unplug the power supply. I plug it right back in and it was back to normal.

My Kenwood KDC-MP232 entered "protect" mode, & I do't know why


This unit has an anti-theft program that is activated when a code is programed.

At this point forward, the power circuit is monitored, thus when the power is disconnected or drops below 12VDC it shuts down and the code must be entered to reactivate the unit and its functions.

Other circumstances that might trigger the anti-theft shut down are...

Bad power or ground connection to head unit.
A weak or faulty battery/alternator.
A blown fuse.
A sudden power surge, as happens when jump starting another car.

As for your personal 4 digit code, I cant help you with that but some high-end car audio dealers offer a diagnostic service that can reset a coded/locked out unit.

Good luck

On display is says "protect" what does that mean?


Try disconnecting the power supply to the back of the mp232 then reconnecting it. This worked for me AFTER doublechecking all of my speaker connections.

Kenwood kdc-mp232 not turning on


check your connections. i believe only the standby wire is connected.. or the built in amplifier detects a short on the speaker wires.
