【Smart Lock LINKEY Function Explanation 1】What is Auto Lock (Automatic Locking)?

What is LINKEY Plus? LINKEY Plus is a smart lock that streamlines your business. In this article, we will introduce the auto-lock feature of LINKEY Plus! What is the auto-lock feature? With LINKEY Plus, you can use the auto-lock feature. After unlocking, the built-in magnetic sensor detects when the door is closed and automatically locks it. The auto-lock activation time (initially set to 5 seconds) can be freely set between 1 to 30 seconds, and the auto-lock feature can also be turned off. When is it useful? Say goodbye to the common worry of "Did I lock the door...?" when going out. Guests do not need to take a physical key when leaving, completely eliminating the risk of them losing the key! Additionally, if the door is not properly locked, you will be notified with an alarm sound. By using LINKEY Plus, you can further streamline your business!
