Go into ur phone settings, security settings, phone and sim. Scroll down to lock code.
To change the code to ur own, select it, and it will ask for the default lock code which is 12345. Once confirmed, it will ask u for ur new code which can be
4 or 5 digits. Pick something u wont forget. Then it will ask u to confirm it.
Now if ur phone has an autolock feature, u can set it by selecting it and selecting user defined and set a time, like 10 or 15 minutes, up to u. Ur phone will lock after
that set time of inactivity. U will still be able to take calls, but need to put the code in to do anything else. Code will be requested each time u turn ur phone on.
Depending on ur nokia, u may have remote lock feature. With this, u set a password, and if ur phone is stolen and ur worried that it hasnt autolocked, u can send that
password to ur phone from any other phone by sms and it locks it.
U may also have the feature to have the phone lock if the simcard is changed and u can enable that too.
Finally, u have pin lock. This locks ur sim card, even if a theif takes it out and puts it in another phone, the code will be required to use ur sim.
To change the pin code, its the same as the lock code change, but the default code u need to put in first is different. Its usually 00000 but if that doesnt work, select
cancel, and call ur service provider, they will give u their sim pin default code, and after uv done that, select pin request on, and it will ask for a code every time u
turn ur phone on.
Its a good idea to make ur pin and lock code the same so u just enter them consecutively on start up
Hope this helps. [answer taken from Yahoo.answers]
