Set the Security Code
There is no device-based "security code" for the AT&T Z331. However, there is a "phone password" that can be user-defined.

Set the Phone's Password

From the standby screen, press Menu.
Select Settings.

Select Security.

Select Change security codes.
Select Phone lock code.
Enter the phone's current password, then press OK.
NOTE: The password is user-defined; there is no default. If a password has yet to be established, the phone will prompt for a new password to be entered and then confirmed.
Enter the desired phone password (4 to 8 digits), then press OK.
Re-enter the new phone password, then press OK.
