For radios whose Serial Number begins with an "M", followed by a six digit number, you can use the following link to work out what your Keycode should be:

That will be 9622

Well, I can confirm that the correct Keycode for Serial Number V078249 is indeed

Assuming that you haven't already used-up all the available attempts to enter the correct keycode you just need to enter the code into your radio! Don't forget that you need to Press #Button 5 once after entering the code to actually enter it into the radio.

What does the display on your radio say?

Further information regarding entering the Keycode may be found here:
