i) use the code 12345

ii) if this doesnt solve, perform firmware update by visiting "http://nds1.nokia.com/files/support/global/phones/software/NokiaSoftwareUpdaterSetup_en.exe"---> this will download a software, u have to install it, run the prog, follow onscreen instructions, bios or firmware will be updated(make sure u already have Nokia PC suite installed, Connected to internet........this is an online update....)

here when we do online firmware update or bios update all the passwords will be lost...........(surely this will work..............)

Thanking you

HI,
You have to type in security code of your phone in order to log into the phone....
By default the security code is 12345 and if you have changed it, you must be knowing....
BUT IF YOU WERE NOT ABLE TO GET INTO THE MOBILE WITH THE 12345 OR IF YOU FORGET THE SECURITYCODE, the one and the only way is to flash the mobile phone(ie, reinstalling the firmware), this cant be done by the normal person, u have to take the phone to nearest service center and flash it, they may charge u very minimal amount......

CAUTION: You may loose all the content stored in the phone memory, be careful,but no other way than doing this
