The default lock code (security) is 0000. and default, PIN1 is 1111, and PIN2 is 2222
If you need further help let me know. If you get it wrong enough you will be asked to enter PUK code. Then you only need to call up your provider and they will assist you.
Thanks,

If "0000" didn't worked try using your commonly use PIN code and that code be it, check also to your Service Provider if there's a master reset for your phone so everything will be back to its default security code.
Hope that helps........
