Keyin appears to be a hospitality access solution focused on enabling digital/remote guest entry workflows (e.g., issuing and managing access credentials for doors/locks) that can be connected to a property’s operational stack. In a PMS integration context, Keyin is typically used to automate the creation, delivery, and lifecycle management of guest access based on reservation events (check-in/check-out times, room changes, cancellations).

When integrated with a PMS, Keyin can help reduce front-desk workload and improve guest experience by supporting self check-in, time-bound access, and centralized monitoring of access activity. Common benefits include fewer lost keys/cards, faster arrivals, and improved operational control through automated credential provisioning and revocation tied to booking status.
