What is it? Forgot your Nokia phone security/lock code, and frustrated trying to guess and reset you phone settings. ? Don't worry, this free online tool will help you to reset your security code without even using cable wires and programming. This can be done simply by means of "Mastercode" What is Mastercode? Mastercode is a 10-digit number that will always be granted once input at a particular device, the same function as your actual security code. You can use the master code to reset/change your security code back to what ever you like. When your Nokia phone asks you for the security code either during start- up or at keypad lock simply enter the Mastercode in replace of your forgotten security code. How to get Mastercode? The Mastercode is specific and unique code to your handset as it is generated using your mobile 15 digit IMEI number (serial number). The IMEI number can usually be found on the sticker underneath the battery or simply by typing *#06# at phones standbye mode. Simply enter your 15 digit serial / IMEI number at the form HERE then click "Get Code". Your master code will then be generated instantly. Then you need to enter this code into your Nokia when prompted for the security code. Nokia security code only composed of 5 digit, but Mastercode has 10 digit. Don't worry, as long as you entered your IMEI correctly, the generated code can replace the actual/forgotten security code. ! Note:: The default security code for all Nokia handsets is 12345 (also known as the Phone Lock Code).
