LG How to Enable or Disable Lockdown Mode

Lock mode is a function that temporarily disables all automatic screen lock unlocks, but when lock mode is enabled, the LG unit can only be unlocked manually using the password, PIN or pattern.

The lock mode must be re-activated each time the power is turned on. This is done by pressing and holding the power key. The "Lock" key is located at the bottom of the menu. This puts the device in sleep mode and can only be unlocked manually.
