Passcode Types

Overview

Passcodes (PIN codes) offer a flexible, key-free method to access a building. This article explains the different types of passcodes available for our locks.

Passcodes are often the most adaptable credential, suitable for a wide range of applications. They do not require any physical medium—such as a card or mobile device—making them simple to issue, share, and manage.

  • Set specific start and end times (accurate to the hour)
  • The code is only valid during the specified cycle
