Looking for radio code for ford focus radio the serial number is m164609

Your Code is: 3771
Insert the radio code by repeatedly pressing button 1 until the first number of the code appears on the display. Press button 2 until the second number of the code appears in the display. Repeat the process on buttons 3 & 4 to complete the code. When the code is entered correctly press button 5 and the radio should unlock. It works very well for me. Let us know how you get on.
