Change Lock
The default lock code for your phone is generally the last four digits of
your phone number. It is advisable to change the default lock code to
a secret code for security purposes.

At the Security sub-menu, select Change Lock. You’re
prompted to enter the new lock code.
2.
Enter the new lock code. You’re prompted to re-enter the new
lock code for verification.
3.
Enter the new lock code again. Your changes are stored.
Note:
Your phone does not allow you to view the lock code for obvious security
reasons. If you change the lock code, be sure to write down or memorize
the new code.
