I had to change the battery in my car, so I need the code for my stereo. Hope someone can help me :) Car: Ford Mondeo 96 Model Stereo: 5000 RDS EON. (No cd player, cassette player only) Serial No.: M21390 - I'm not quite sure which of these two is right, but here is the other serial number. : M213908. But I think the first serial number, which I wrote down is the correct serial number. I also tried to find the correct code a few times before, so now when I turn on the radio, it comes up "Locked" on the screen. So if anyone has any tips on how I can get rid of this, it would be great. I really hope someone can help me with this problem :)))

To deactivate the "Locked" mode, turn the radio unit on while holding the "6" preset button.

You will have 3 additional attempts to enter the code.

The code for M213908 is 8851.
