| 1 | Define the access requirement | User volume, entry frequency, and access schedules | Document daily users, peak traffic, and restricted time periods before requesting quotes. | A lock designed for occasional office use may be unsuitable for high-traffic facilities. |
| 2 | Check door and frame compatibility | Door material, thickness, backset, handing, and existing hardware | Verify measurements and fire-rating requirements before purchase. | Fit-related modifications can add installation labor and may affect safety compliance. |
| 3 | Compare credential methods | PIN, RFID card, mobile credential, mechanical key, or biometric access | Select at least one managed backup method for outages or lost credentials. | The right combination reduces lockouts and simplifies employee access changes. |
| 4 | Measure battery performance | Battery type, expected life, low-power alerts, and emergency access | Budget for battery replacement at least annually unless documented testing supports a longer interval. | Battery visits and emergency callouts are recurring operating costs. |
| 5 | Evaluate connectivity | Bluetooth, Wi-Fi, wired network, gateway, and offline operation | Confirm what happens when power, internet, or cloud service is unavailable. | Offline credentials and local schedules help maintain access during outages. |
| 6 | Review audit and administration tools | Event logs, user roles, remote revocation, exports, and retention | Look for searchable entry records and role-based administration. | Reliable records support security reviews and faster incident investigation. |
| 7 | Assess security and resilience | Encryption, firmware updates, tamper alerts, and administrator controls | Require documented update procedures and separate administrator accounts. | Security depends on both the hardware and the way it is administered. |
| 8 | Calculate installation complexity | Wiring, door alignment, network setup, permissions, and commissioning | Obtain a labor estimate per door, including removal of old hardware and testing. | Installation can equal or exceed the hardware cost on older or unusual doors. |
| 9 | Forecast maintenance needs | Battery changes, cleaning, firmware, service visits, and spare parts | Create a five-year maintenance allowance instead of budgeting only for purchase price. | Predictable maintenance makes operating costs easier to control. |
| 10 | Compare long-term value | Five-year total cost, labor savings, scalability, and replacement risk | Use total cost of ownership rather than the lowest initial price. | A higher upfront cost may be justified if it reduces administration and service work. |
