Smart-Lock Access Management
A centralised platform for issuing, scheduling, and revoking time-limited PIN codes across multiple smart locks — giving property managers full visibility and control over who enters, when.
Booking or Assignment
A booking is created (manually or via integration); the system determines the access window and the target lock.
PIN Code Generation
A unique time-limited PIN is generated and pushed to the smart lock via the manufacturer API.
Code Delivery
The PIN is sent to the guest or staff member by SMS and email, with clear instructions and the access time window.
Entry & Logging
Guest uses the PIN to unlock the door; the entry event is logged with timestamp and user identity.
Automatic Expiry
At the end of the access window the PIN becomes inactive automatically; no manual revocation is needed.
Project Scope & Capabilities
Multi-Lock Management Dashboard
A single web interface for managing PIN codes across any number of smart locks — assign, schedule, extend, or revoke access in seconds without touching any lock hardware.
Time-Limited Access Codes
Every PIN is scoped to an exact start and end time; the lock rejects it outside that window automatically, eliminating stale keys and forgotten revocations.
Full Access Audit Log
Every entry and exit event is timestamped and logged, providing a complete audit trail for security compliance, dispute resolution, and occupancy reporting.
Implementation Timeline
| Phase | Duration | Description |
|---|---|---|
| Discovery & API Evaluation | Week 1 | Audit existing lock hardware, evaluate smart lock API capabilities, map access requirements, and design the PIN management data model. |
| Core Development | Weeks 2-3 | Build Next.js dashboard, Supabase data layer, smart lock API integration, PIN generation engine, and Twilio SMS/email delivery. |
| Hardware Testing & QA | Week 3-4 | On-site lock testing across all access scenarios, time-window boundary validation, expiry and revocation testing, and load testing. |
| Deployment & Training | Week 4 | Production deployment, property manager training, monitoring setup, and handover documentation. |

Zero
Stale Key Incidents
Automatic time-scoped expiry eliminates all incidents of unauthorised access via forgotten or unrevoked codes.
–100%
On-Site Key Handovers
Digital PIN delivery removes the need for physical key handovers entirely, saving staff time on every booking.
Full trail
Audit Compliance
Every entry event is logged with user, timestamp, and lock ID — providing a complete record for compliance audits.
Testing & Quality Assurance
Automated Testing
- ✓ PIN generation uniqueness and collision tests across 10,000 codes
- ✓ Smart lock API push reliability validated under concurrent booking load
- ✓ Time-window boundary tests: access granted at start, denied after expiry
- ✓ Twilio SMS and email delivery reliability with 500 test notifications
Manual Validation
- ✓ On-site testing of all access scenarios on physical lock hardware
- ✓ Revocation flow validated: PIN deactivated within 5 seconds of manual revoke
- ✓ Dashboard UX review by property manager with 5 test bookings
- ✓ Audit log accuracy verified against physical entry records
"We manage 12 rental units and used to spend hours every week on key handovers and chasing guests. Now every guest gets their PIN automatically and the whole process runs without us."
