At a glance
THE HANDOVER IT CAN REMOVE · EDITORIAL VIEW
Create a fixed, clearly labelled key-collection point with a physical keypad. Useful where the customer needs an existing key rather than a new electronic door lock.
Potential rental fit
- Fixed key-collection points
- Bookable-space key handover
Applications to evaluate, not confirmed deployments of this exact SKU.
What the site needs
Plan a suitable wall and fasteners; SK4 is not shackle-mounted. Offline PIN validation avoids a live connection for opening, while Bridge-based online features introduce additional dependencies.
Maintenance & recovery
Schedule AAA battery replacement before depletion. The sheet specifies 5 V USB-C emergency power for authenticated access. Carry the right source and cable; do not assume every guest phone supplies power.

Costs & limitations
LIMITATIONS & QUESTIONS BEFORE SELECTION
- The product sheet has an apparent net/gross weight error. Confirm with the supplier before installation planning.
- The sheet includes generic door auto-unlock wording; this is not treated here as a verified rental feature.
- Wall substrate, anchors and guest key-return checks remain operational responsibilities.
The full cost to compare
Include installation, spare keys, battery checks and return reconciliation. An access log or shut lid is not proof that the correct key is present for the next guest.
