Easy to use digital code lock suitable for areas where a group of people must have access. The user chooses a 4-digit code when locking the door. When the door is opened, the code resets and the user chooses a new code when locking again. The unit clearly indicates if it is open or locked and when batteries need to be changed.
Safety features like inspection code and master code are built into the code lock unit. Accessories are battery packs and a protective screen that prevent peeking.
