  • What are ‘virtual keys’?

    A virtual key is actually a permission saved in an encrypted format to a user’s smartphone app and in your ENTR™ lock.

  • How can I create a virtual key?

    Every ENTR™ system has an administrator, generally one of the homeowners. The administrator can create and distribute virtual keys for other users with his/her smartphone app. The app creates an encrypted virtual key on the administrators smartphone and the lock itself. using a unique verification process. This allows the administrator to distribute virtual keys and turn them off whenever necessary.

  • Do I need to connect to the Internet or Wi-Fi to operate ENTR™?

    No. ENTR’s app uses Bluetooth to communicate with the door unit, eliminating the need for an active network.

  • Can all family members have access to ENTR's smartphone App?

    Yes, If they have a compatible smartphone. The smartphone app can be downloaded for free from the App Store or Google Play. With the administrator’s permission, the user can then operate ENTR™ based on the scheduled authorizations.

  • Why does the Android App requires 'Location Permissions' ?

    The ENTR Lock uses BLE (Bluetooth Low Energy) in order to communicate with your Android Smartphone.

    Starting from Android 5.0, the ‘Bluetooth’ permission isn’t enough in order to be able to scan for BLE devices.

    In Android 5.0, the OS requires an App to have ‘Coarse Location’ permission (or ‘Fine Location’) in order to scan for BLE devices.

    The ‘Location’ service can be ’disabled’ while the App is running.


    In Android 6.0 and above, the requirement was hardened so that the App must have ‘Coarse Location’ permission (or ‘Fine Location’) and also ‘Location’ services need to be ‘enabled’ when the App is running, so it can scan for BLE devices.


    Hence, the ENTR Android App requires ‘Location Permissions’ due to Android’s requirements.
