GuestsKey - Automate smart lock codes for your short-term rentals

by•
GuestsKey connects your property management system (OwnerRez, Hospitable) to your smart locks (Seam, SmartThings) and automates the entire guest access lifecycle — no manual codes, no forgotten lockouts. Bookings sync automatically. Guest codes generate from their phone number, activate at check-in, and expire at checkout. Cleaner codes work across all properties with one click. One-time keys for vendors auto-delete when done.

Hey Product Hunt, I built GuestsKey after watching short-term rental hosts spend 20+ minutes per booking manually creating and deleting door codes — and occasionally forgetting entirely, leaving guests stranded at 11pm. GuestsKey connects OwnerRez or Hospitable to your smart locks and handles the entire code lifecycle automatically. Guest codes generate from their phone number, activate at check-in, and expire at checkout. No dashboards to check. No manual steps. A few things I'm proud of: - Codes generate from guest phone numbers (no random PIN to communicate) - Cleaner management: add once, works on all properties instantly - Self-healing: if a code fails to apply, the system retries and alerts you - Built for multi-property operators — one account, unlimited properties Would love feedback from STR hosts and property managers in the community. What's your biggest pain point with smart lock management today?
