past the security code or not so I dont want to waste the money wanted advice before anything

The default security code for a Nokia 1100 phone is "12345" or "0000" If it has been changed and you don't know it, You can do a master reset to your mobile phone. This could restore your phone with default factory settings. Including the security code.
