SOURCE: Nokia N73 security code

The default security code for Nokia is 12345
IMEI: 359568011016758
Master code: 4444376533
Close all applications on your phone.
With your phone switched ON, remove the battery.
Then remove the SIM card.
Replace the battery without the SIM card and switch your phone on.
Type in the security codes (any code) until the phone request the Master code, when it does, leave your phone still, don’t use it for 15 minutes, then type in the Master code.
This is the code needed to reset the Security code, nothing else, and it’s for your phone only.
If it does not request the Master code, your phone will have to be connected to a computer and an unlock box to restore the Security code.
