Access Control That Follows the Lease: PDK and Della OS

The short answer: Della OS works with PDK (ProdataKey) cloud access control. When a lease becomes active in Yardi, Entrata, RealPage, AppFolio or ResMan, Della OS gives the resident access to the right building, amenity and unit doors. When the lease ends, that access is removed. PDK lists Della Connect among the smart apartment software it integrates with. At Regius Square in Salt Lake City, PDK runs on Della OS alongside dormakaba smart locks, Interel thermostats and ButterflyMX intercoms.

Why access control needs the lease

PDK manages doors, readers and credentials (mobile, keycard and fob) from the cloud. What it can't know on its own is who lives where. Without a link to the property management system, staff add and remove residents by hand, and credentials can outlast the lease.

How it works with Della OS

• Move-in: access is issued when the lease becomes active, and the resident uses it from the Della Resident app.
• Transfers: access follows the resident to their new unit.
• Move-out: access is removed automatically when the lease ends.
• Amenity bookings: when a resident books an amenity, their access to it updates automatically.
• One dashboard: site teams manage PDK alongside locks, thermostats, intercoms and Wi-Fi, instead of in a separate portal.

Keeping your PDK hardware

Della OS works with existing PDK installations, so a community can add lease driven access without replacing controllers or readers. Compatibility is confirmed before installation, and the work is done by certified integration partners with Della's platform team behind them.

A live example: Regius Square

Regius Square, managed by Asset Living, connects its Yardi PMS to PDK access control, dormakaba locks, Interel thermostats and ButterflyMX intercoms through Della OS. It won the Parks Associates 2025 Property Innovation Awards. Read the Regius Square story.
