2000 mitsubishi galant, changed battery , radio is saying off, i dont know the code, now what

Hi! I had this same problem on my 2000 mitsubishi galant. To get the code, you have to first get the serial number which is labeled on the stereo. I had to pull the whole stereo out of its setting to find the label. Then if you call the dealer with the serial number (and I think you need a variety of other info proving the car isn't stolen) they will give you the code and tell you how to type it into the radio.

The hardest part for me was getting the stereo out of its setting. On my car there is fake wood plastic all around the stereo and air/heating dials. You have to pull the wood casing off (if you use a screw driver around the edges, it should just pop off). Then unscrew the stereo from the rest of the car and pull it out (i felt like i was stealing the stereo from my own car haha). The screw was all the way in the back, closer to the hood of the car than to the driver seat.

Hope this helps. The code should just be a four digit number...for me this was a lot of work for a small problem...but worth it compared to driving around in silence.
