I have entered the radio code wrong in my Renault Megane, how do I get it unlocked again?

To reset a radio that is semi-locked due to  too many wrong codes , leave it SWITCHED ON...UNDISTURBED until it automatically resets itself.

This may take several hours as the waiting time can double after each wrong code.(however normally it is only an hour or two)

Make sure you are using the CORRECT CODE.

Any doubt then ask another question quoting the RADIO MAKE + MODEL plus ALL the LETTERS+NUMBERS found on any labels, barcodes or stamped in the metal casing
