Follow the steps below for locking and unlocking your phone.
Lock Your Phone
When your phone is locked, you can only receive incoming calls and messages or make calls to 911. Lock Mode also restricts access to menus and the volume key.
Press the Menu softkey > Settings > Phone Settings > Security.
Enter the four-digit lock code.
The default lock code is the last four digits of your mobile phone number
Select Lock Phone.
Unlock Your Phone
From standby mode, press UNLOCK (right softkey).
Enter your lock code.
Change the Lock Code
Your phone does not allow you to view the lock code for obvious security reasons. If you change the lock code, make sure to write down or memorize the new code
Press the Menu softkey > Settings > Phone Settings > Security > Change Lock.
Enter the new lock code.
Enter the new lock code again.
