**The problem it solves** STR hosts in apartment buildings with intercom or buzzer systems struggle to offer contactless self check-in without installing new hardware or handing out physical keys. **What Lowkey does** Lowkey is a mobile app that enables apartment and condo building hosts to manage their intercom or buzzer remotely without hardware installation, enabling self check-in for short-term rental guests. The app works with any buzzer system that dials a mobile phone number by replacing the host's personal number with a virtual Lowkey number and routing buzzer calls through the app with automated unlock responses. **How it works** Features include timed guest access so the buzzer unlocks automatically during a guest's stay window, personalised access codes guests can use for private buzzer entry, scheduled access for cleaners and service providers independent of guest stays, push notifications when a guest arrives and triggers the buzzer, activity logs showing all entry events, and the ability to revoke access at any time. Multiple team members can be set to receive buzzer calls. The app integrates with Guesty to sync reservation data and automatically configure access windows. Lowkey is a pure software solution priced on a subscription basis. **Who it's for** Germany-based and other urban Airbnb hosts, short-term rental property managers, and co-hosts who manage apartments in buildings with intercom systems and want contactless self check-in without keybox hardware or in-person key handoffs.
