| Lock Construction | Smart Deadbolt | Replaces or operates a standard deadbolt through a motorized thumb-turn or exterior keypad. | Automatic locking, mechanical key override, incorrect-code lockout, tamper alarm, and encrypted wireless communication. | Residential apartments, villas, rental homes, and retrofit projects. | Confirm door thickness, backset, deadbolt dimensions, handing, cylinder compatibility, and emergency egress requirements. |
| Lock Construction | Mortise Smart Lock | Integrates the electronic reader, motor, latch, and deadbolt into a mortise case installed inside the door edge. | Multi-point engagement options, anti-pick cylinder options, audit trails, access scheduling, and concealed wiring. | Hotels, offices, high-end residences, and institutional buildings. | Verify mortise case dimensions, spindle position, door preparation, fire-door compatibility, and local egress codes. |
| Lock Construction | Smart Lever Handle | Combines a lever handle and electronic access reader in one unit, usually with a spring latch. | PIN authentication, RFID or NFC credentials, passage mode, privacy mode, and low-battery warning. | Interior rooms, offices, serviced apartments, and light commercial doors. | Check latch size, spindle dimensions, door opening direction, handle height, and accessibility requirements. |
| Credential Method | PIN Code Access | A user enters a programmed numeric code on a touch keypad or physical keypad. | Temporary codes, one-time codes, failed-attempt lockout, anti-peep input, and administrator permissions. | Short-term rentals, family homes, offices, and shared facilities. | Review code length, code capacity, offline operation, event storage, and protection against shoulder surfing. |
| Credential Method | Fingerprint Recognition | A biometric sensor captures fingerprint features and compares them with locally stored templates. | Liveness detection, template protection, local matching, failed-scan limits, and alternative credentials. | Residential entrances, staff-only areas, and small commercial premises. | Ask for performance data under wet, dry, dirty, or damaged-finger conditions and confirm privacy compliance for biometric data. |
| Credential Method | RFID / NFC Access | A card, key fob, or compatible mobile credential is read through short-range radio communication. | Encrypted credential storage, revocation, anti-cloning measures, access levels, and event logging. | Hotels, offices, student housing, and multi-tenant buildings. | Identify the supported frequency and credential technology, card-security method, reader range, and system interoperability. |
| Connectivity | Bluetooth Low Energy | A nearby smartphone communicates directly with the lock using low-power wireless connectivity. | Encrypted pairing, device authentication, digital keys, permission control, and offline credential support. | Residential use, offices, and access points where local phone control is sufficient. | Test phone compatibility, pairing recovery, range, key sharing, battery impact, and operation without cloud access. |
| Connectivity | Wi-Fi or Gateway-Connected Lock | The lock connects directly to Wi-Fi or communicates with a nearby gateway for remote management. | TLS-protected communication, role-based accounts, remote revocation, activity alerts, and firmware updates. | Property management, remote monitoring, vacation rentals, and connected home systems. | Confirm supported Wi-Fi bands, gateway requirements, cloud-region availability, data ownership, subscription terms, and offline fallback. |
| Core Cybersecurity | Secure Firmware and Updates | The lock verifies firmware integrity during startup and receives authenticated software updates. | Secure boot, signed firmware, encrypted update delivery, rollback protection, and vulnerability-response procedures. | All connected smart lock categories, especially remotely managed installations. | Request a software-support period, update policy, vulnerability-reporting channel, penetration-test summary, and end-of-support process. |
| Physical Security | Tamper and Forced-Entry Protection | Sensors identify abnormal movement, repeated credential failures, enclosure opening, or forced rotation. | Tamper alarms, hardened escutcheons, anti-drill components, clutch mechanisms, mechanical override, and event records. | Exterior doors, commercial entrances, and high-traffic access points. | Check independent durability testing, cylinder resistance, latch strength, IP rating, temperature range, and local building-code compliance. |
| Power and Reliability | Battery-Powered Smart Lock | Rechargeable or replaceable batteries power the motor, reader, processor, and wireless module. | Low-battery alerts, emergency external power, mechanical override, battery protection, and retained access settings. | Retrofit residential installations and doors without existing low-voltage wiring. | Compare battery chemistry, claimed cycle life, standby consumption, emergency power interface, operating temperature, and serviceability. |
