All-in-one smart lock

Cellular connectivity, built into the deadbolt lock.

NB-IoT, LTE-M and Bluetooth in one body. The Cellular Deadbolt works with all major wireless carriers, so there is nothing extra to install at the door.

  • NB-IoT
  • LTE-M
  • Bluetooth

Real-time monitoring

Live alerts the moment a wrong code is entered or the battery runs low — no manual sync, no bridge to babysit.

Easy, simple set-up

One lock, one installer. No extra technicians and no external devices to mount or power.

No external hub needed

Hubs can be tampered with or unplugged. An all-in-one lock removes that failure point entirely.
