Description
The Lockly Guard Duo Interconnected Edition turns the most awkward door in your building — the one with both a latch and a deadbolt — into a single smart unit operated by one motion. The patented Dual-Locking Technology won the 2025 New Product of the Year from Security Today, and the reason is simple: a single lever motion now controls both the latch AND the deadbolt at once. For residents, that’s faster entry and code-compliant single-motion egress. For property managers, that’s one device to credential, audit, and battery-swap instead of two.
This product page covers two variants of the same lock — choose your edition from the dropdown above based on your building’s existing access infrastructure.
Choose your edition: Standard (PGD679DW) or Z-Wave (PGD679DZ)
Standard Edition (PGD679DW) ships with the Lockly Wi-Fi hub included in the box. The lock itself is Bluetooth; the included hub plugs into a wall outlet within range and bridges the lock to your WiFi network, enabling remote unlock through the Lockly app and full LocklyOS audit-log streaming. Pick this for single-family residential, low-volume multifamily, vacation rentals, and any deployment where the lock is the access platform.
Z-Wave Edition (PGD679DZ) uses a Z-Wave Plus radio to communicate directly with your building’s existing Z-Wave alarm system — Alarm.com, SmartRent, Brivo, and similar platforms. The lock joins the building hub natively; no Wi-Fi hub is required. Pick this for multifamily portfolios where the access infrastructure is already Z-Wave-based and you want the door-level lock to plug into it natively.
Both editions ship with three PGA803WH RFID Tag Keys and are available in Matte Black or Satin Nickel finishes.
Where the Lockly Duo fits
- Premium multifamily unit doors with both a latch and a deadbolt — the most common premium-apartment configuration
- Office suites consolidating two locks into one smart unit
- Single-family residential wanting voice control across Google Assistant, Alexa, Apple Home (via the PGH260 Matter hub), and Samsung SmartThings
- Vacation rentals issuing premium guest experiences with a single device handling both the deadbolt and the latch
- Condominiums offering smart-access amenity upgrades to residents
Why single-motion egress matters
On a traditional apartment unit door with both a latch and a deadbolt, exiting requires operating two things — the deadbolt thumbturn AND the latch handle. Building codes increasingly require code-compliant single-motion egress in residential and commercial-residential occupancy, and the Lockly Duo’s interconnected mechanism delivers it natively. One lever motion releases both. Fire marshals, ADA inspectors, and building inspectors increasingly recommend the Duo as the upgrade path for unit doors with both lock types. (Always check your local life safety compliance codes and confirm any door modification with your Authority Having Jurisdiction.)
