    I bought a used car with this Kenwood system. We had the starter replaced the other day and now the radio won't work and it's asking for the code. I have no idea what it is.

Anyone know code for kenwood kdc-mp-232

Here is the manual:

From what I have read, you can set a new code, but you need to know the old code. You can also reset the code, but you need the old code. You can also disable the code, but you need the old code as well.

I would suggest trying different combinations of 4 digit codes, there are only 256 combinations. I am sure you will figure it out.

Protect on the screen.

PROTECT shows up on your screen when one of the speaker wires is grounding out on something. Check all the speaker wire connections and re-insulate any that may be suspicious. Look behind the player and check those and you may have to check at the speakers as well. If your car has an amp or subwoofer installed, check at the connections there as well. After finding your grounding issue hit reset on the radio and you will be up and running.. Happy listening. K

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

"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.
