| Fingerprint Access |
A biometric sensor verifies an authorized fingerprint and releases the lock without requiring a physical key. |
Widely available |
Convenient keyless access for households, apartments, offices, and rental properties. |
Choose models with encrypted storage, failed-attempt protection, and an emergency backup method. |
| PIN Code Keypad |
Users enter a preset numerical code on a touch or push-button keypad to unlock the door. |
Widely available |
Useful for families, service providers, short-term rentals, and situations where sharing a physical key is impractical. |
Look for temporary codes, automatic locking, weather-resistant controls, and protection against repeated guessing. |
| Mobile App Control |
A smartphone application can lock or unlock the door, manage users, and display access activity through a wireless connection. |
Widely available |
Enables remote access management and convenient monitoring when the owner is away from the property. |
Check local network compatibility, account security, software support, and whether remote access requires an additional hub. |
| Temporary and Scheduled Access |
The system creates time-limited or recurring credentials for guests, cleaners, deliveries, tenants, or staff. |
Common in connected models |
Reduces the need for copied keys and helps control access across different time zones and property schedules. |
Confirm that access permissions can be revoked immediately and that local time settings are handled correctly. |
| Real-Time Activity Logs |
The lock records events such as unlocking, locking, failed attempts, and low-battery warnings. |
Common in app-connected models |
Provides greater visibility for homeowners, property managers, and commercial users. |
Review data-retention policies, user permissions, notification settings, and privacy requirements in the destination market. |
| Video Doorbell and Camera Integration |
A camera and doorbell system captures visitors, supports two-way communication, and may connect with the entry lock. |
Increasingly available |
Improves visitor verification, delivery awareness, and perimeter monitoring. |
Check image quality, night visibility, storage options, privacy rules, and compatibility with the selected door system. |
| Voice Assistant Compatibility |
Supported voice platforms can report lock status or perform selected commands after authentication. |
Available on selected models |
Adds hands-free convenience and can connect the entry door to broader home automation routines. |
Unlock commands should require an extra PIN or equivalent security control to reduce unauthorized access risk. |
| Auto-Lock and Door-Position Sensing |
The system automatically locks after a selected interval and may use a sensor to determine whether the door is closed. |
Widely available |
Helps prevent doors from being left unlocked and supports safer daily routines. |
Correct sensor alignment is essential; installation should account for door movement, frame tolerances, and local climate conditions. |
| Low-Battery Alerts and Backup Power |
The lock warns users when power is low and may provide emergency power contacts or a mechanical key override. |
Widely available |
Maintains access reliability during battery depletion or temporary power problems. |
Verify battery type, expected service interval, emergency access procedure, and availability of replacement parts locally. |
| Wireless Connectivity |
Bluetooth, Wi-Fi, or a low-power mesh protocol connects the lock to a phone, hub, security system, or home automation network. |
Widely available |
Supports remote control, notifications, integrations, and flexible installation options. |
Confirm regional wireless standards, operating range, network stability, encryption, and offline functionality. |
| Multi-Factor Authentication |
The system combines two or more verification methods, such as a password, trusted device, biometric credential, or one-time code. |
Optional on selected systems |
Adds protection against compromised passwords and unauthorized remote entry. |
Prioritize systems with encrypted communication, secure account recovery, and regular security updates. |
| Smart Home and Security System Integration |
The entry door communicates with lighting, alarms, occupancy sensors, and other connected devices through supported protocols. |
Available on selected models |
Allows automated routines such as turning on lights after entry or activating an alarm when the property is secured. |
Check protocol support, regional certification, interoperability, subscription requirements, and future software support. |
