In between calls and other operations with the phone, its keyboard (unless, of course, this is a "clamshell") must be protected from accidental keystrokes. So you will avoid accidental dialing and calling, sending "empty" SMS and other costly steps. For this purpose, a lock is set on the telephone keypad.

Instructions
Step 1
On some phone models, the lock is set and unlocked by holding down the hash (# symbol) or asterisk (sometimes called a snowflake, denoted by *). Lock activation signals - a short vibration and a corresponding message on the phone display.
Step 2
On other models, you need to press two keys in turn - the menu and the "asterisk". There will be no vibration, but a message will appear on the display. You can remove the lock in the same way - menu + asterisk.
Step 3
To automatically turn on the lock after a certain time, go to the phone settings, then "keypad lock". Select the option "enable" (or "active"), then set the time interval after which the blocking will be activated.
