At a glance
THE HANDOVER IT CAN REMOVE · EDITORIAL VIEW
Remove the key meeting while retaining existing locks on a sauna, cart or rental asset. Shackle or wall mounting can reduce the need to modify the thing being rented.
Potential rental fit
- Equipment that still needs a key
- Bookable spaces with physical-key entry
Applications to evaluate, not confirmed deployments of this exact SKU.
What the site needs
Offline PIN entry and AAA batteries can avoid a powered access installation. Check usable space with the actual keys or fobs and follow the sheet’s sheltered-installation recommendation despite its IP66 claim.
Maintenance & recovery
Plan battery replacement and a compatible USB-C emergency-power source. Emergency power permits authenticated opening; it does not recharge the AAA batteries or prove that a missing key was returned.

MANUFACTURER SPECIFICATIONS · REVIEWED 3 SEPTEMBER 2026

- Protection and siting

Costs & limitations
LIMITATIONS & QUESTIONS BEFORE SELECTION
- Storage and weight differ between the sheet and newer manufacturer comparison chart; do a physical key/fob fit check.
- PIN activity logs and battery status need synchronisation; offline access is not the same as live telemetry.
- A box-closing event does not confirm that the right key was returned. Plan key reconciliation and recovery.
The full cost to compare
Include duplicate-key management, mounting, battery visits and lost-key recovery. Reusing several existing keyed access points may be more economical than replacing all their locks.
Request current local pricing for the exact SKU, required accessories, software and installation. No cross-market price comparison is implied.
Source documents & verification status
