How to Reset the Code for a W580i

The Sony Ericsson W580i is designed to operate on GSM networks. It uses a small card called a SIM to hold your subscriber information and connect your device to the network. When it comes to codes, the W580i utilizes two different codes--a PIN code, designed to protect your SIM card in the event your phone is lost or stolen, and a security code to lock your entire phone from unauthorized use. You can reset either code through the phone's security options.

  Press the "Menu" key from the home screen. Highlight and select "Settings."
