Case Study: Smarterkey achieves secure, keyless property access via SMS with Twilio

Smarterkey opens Doors by Simply Sending a Text Message with Twilio

Smarterkey, founded in London in 2012 by brothers David and Simon Moss, offers a cloud-hosted guest access control platform and mobile app that removes the need for physical keys. The company set out to solve a common problem for rental owners — how to let guests into properties securely when the owner cannot be present — while avoiding locksmith call-outs, hidden keys and coordination hassles.

Smarterkey’s solution uses Twilio two-way SMS validation to authenticate guests, triggering a nearby Smarterkey Hub to operate an electronic lock and open the door in seconds without requiring WiFi. The result is fast, secure remote check-in that works with any phone, reduces key-related security risks and operational friction, and positions Smarterkey for partnerships with peer-to-peer rental platforms and broader domestic use.
