Introducing NB-IoT Smart Access

Global enterprises trust Digital Keys - our featured customers

Connected smartlocks with unprecedented security and no Wi-Fi

Our smartlocks use NB-IoT which is a new communications technology (part of 5G standards) to connect to the internet, and not Wi-Fi, meaning we can take advantage of mobile network encryption and security features. Wi-Fi smartlocks are insecure, require onsite equipment and drain batteries very quickly

In addition to start of the art-security NB-IoT means longer battery life, no onsite equipment, better reliability and lower costs.

Works with NB-IoT

Take advantage of mobile network encryption and security features including IPSEC security, Private VPN, 2048 bit RSA Chipset security, and 256 bit SSL encryption.

Mobile Network Security

Unlock with your smartphone, receive text messages and live notifications as to when your lock was opened/closed and by whom at what time 

Live notifications

Digital Keys App

All NB-IoT Smartlocks work with the FREE Digital Keys app. Create time-sensitive digital keys in seconds and manage access to your assets from anywhere at anytime.
