How to Lock the Keypad on a Samsung Cell Phone

Equipped with text capability, a built-in phone book and controls for adjusting the volume and display, Samsung cell phones also come with an additional feature—the ability to lock the keypad. The keypad lock not only keeps you from accidentally dialing a number if the phone is in your pocket, but it keeps others from using your phone if you leave it on a desk or counter. A personal identification number is assigned to the keypad lock and the PIN must be entered before the cell phone is unlocked.
