Try to format your mobile. To format your mobile switch off your mobile. then press *(star button) , 3 (three no.) and Green Key ( use to pick up phone) . Start your phone by pressing it and your phone will be formated.
You can backup your data before formated if you don't want to loose anything.

    It may be asking for a security code. That is a 5 digit number.

    Put the original SIM in the phone, in tools, settings, phone, security turn off phone security code.

    You should be able to use your phone with any SIM card now.

    SIM lock and PHONE lock are different and do a different job.

    SIM locks the card, to prevent anyone else having access to your personal details, stored on the card.

    Phone locks the phone, to prevent anyone else using it with another SIM card.

You can access the phone using the PUK code provided in your phone. once you access it, i dont think you can change the code as you dont know the current one but surely can disable it..!!
