I had to replace a bad battery.  After introducing power back to the vehicle the raido was put in to "code" mode.  Forgetting what the code was, I entered the wrong one three times, therefore putting the radio in to "off" mode.  Of course I found the right code but it was too late for I was locked out of the radio.

I phoned Mitsubishi service and they were able to provide me with a solution.  They instructed me to put the key in the ignition, turn it to Accessories and leave the driver's side door open for one hour.  When I came back the radio was out of "off" mode and back to "code" mode.  I entered the correct code and the radio unlocked.

Hey MonSport,

Thanks a lot for helping me out with unlocking the radio. I won't lie, I was a bit skeptical at first. But I gave a try and it worked!!  I purchased my car about six months ago and the battery died a while back. And ever since then the radio has been locked. It is harder for me to get in contact with mitsu since I live in Europe. So I still don't have the code for my radio, but I already got the serial # for it. And now that the radio is unlocked I can tackle getting the code from the states somewhere. I tried that radio-code.com site but it didnt have any luck with them. I couldnt even get the paypal to work, so it raised some concern.

Well, once again thanks a lot for the info... As soon I get it booming again I'll keep you posted. Pics coming soon!!
