Locking Your Keyboard and Screen
Locking Your Keyboard (Keyguard)
The Keyguard feature locks the keyboard so that buttons aren’t accidentally pressed or 
items on the screen aren’t activated while your device is in a pocket or bag. 
By default, Keyguard turns on whenever the screen is off. Each time you wake up the 
screen, you must turn off Keyguard to unlock the keyboard and use your device. 
To turn off Keyguard, do the following:
1.
If the screen is off, press Power/End 
 to wake up the 
screen.
2.
Press Center 
 to turn off Keyguard.
To turn on Keyguard, press Option 
 and then press 
Power/End 
.
You can change how quickly Keyguard turns on, or you can disable 
the feature altogether. To change the Keyguard settings, do the 
following:
1.
Press Applications 
 and select Prefs . 
2.
Select Keyguard.
Tip:
In addition to locking your keyboard and screen as described here, you 
can also lock your phone, your device, and individual entries. See the 
User Guide for details.
