The display shows "SECURITY LOCKED" because you (or someone else) have made at least 10 invalid attempts to enter the code.
To reset the LOCKED condition:
1. Turn the radio OFF.
2. Press and hold the "6" preset button.
3. Turn the radio ON.
4. Continue to hold the "6" preset button until the radio prompts for the code (this may take up to 10-40 seconds).
Please only enter the correct code into the radio. If you continue to make invalid attempts, after 3 (or 1 for some radios) more invalid attempts the radio will be permanently locked. The display will show "SECURITY LOCKED" again but the radio will not respond to the reset procedure described above. Should this occur, only a professional decoding specialist will be able to unlock the radio.
If you do not know the code, it can be determined from your radio serial number. The radio serial number is a letter and six digits (e.g.: M143443). If the serial number begins from "M", "L" or "C" - I can provide the code for you. If the serial number begins from "V" - unfortunately, only a Ford dealer can obtain the code.
