So you don't know or you have forgotten your Nokia Security code? Don't worry the solution lies in this very page! No data cable needed with this new solution. All you need is a Master Code!Forgetting your security code can be frustrating. For example You need this code when you want to reset your phone settings.
So What is a Master Code I Hear you Ask?
Well, lets assume you have forgotten your security code. The master code is a 10 digit number that will always be accepted as if it were your actual security code.
You can use the master code to change your security code back to what ever you like. When your Nokia handset asks you for the security code simply enter the master code.
How do you Generate the Master Code?The master code is specific to your handset and is generated using the handset 15 digit IMEI number (serial number). The IMEI number can usually be found on the sticker underneath the battery or by typing *#06# into the phone keypad.
Simply enter your 15 digit serial / IMEI number into my online tool (see link below). Your master code will then be calculated instantly.
Which Nokia Models will this work for?
The calculated master code will only work for DCT3 and DCT4 Nokia phones. It will not work with the newer BB5 handsets. See below for a rough guide or look at my Nokia generation list to check if your model is supported. The feedback I have received is that's IT WILL NOT WORK FOR THE 6230i model (the 6230 is fine).Compatible phone models
I plan to write a security code tutorial for BB5 handsets shortly (sadly the solution for these handsets is not as simple)
