The code for serial number M187848 is, indeed, 6661.

However, if your radio is showing "Lock10" then I'm afraid that means you or someone else has tried to enter the code wrongly or the wrong code too many times, and the radio has become locked. This is a security measure.

Solution, I'm afraid, is a visit either to a car radio specialist or Ford Main Dealer. Neither are likely to be particularly cheap.

Practical solution? Buy another radio on Ebay. Will probably work out cheaper but make sure you get the code with it.
