How to lock the door when the smart lock is outside?

Use mobile phone applications, use password keyboards, use fingerprint identification and other methods.

1. Use the mobile phone application: By connecting the smart lock with the mobile phone, you can remotely control the status of the smart lock to lock the door. This is a convenient and quick method, as long as you ensure that you have downloaded the correct brand and model of applications and set up remote access rights.

2. Use password keyboard: No intelligent access control equipment equipped with higher-end technology (fingerprint identification) has this function, but it will have a digital password input board built in. When inputting from the outside, you only need to input the correct combination to complete the operation. Be sure to remember which number combinations you have set and whether you have enabled security options such as anti-guessing.

3. Use fingerprint identification: Only when high-end or professional fields need to reach a safe level will such facilities be considered for installation. When they are used externally, just put your finger on the fingerprint reader to complete the operation. The advantage of this method is to ensure that only authorized personnel can enter the room or building.
