Electronic door locks bring keyless convenience, stronger access control, and app driven security to homes, rentals, and offices. Whether you need a smart deadbolt for the front door, a keypad lock for side entries, or a biometric lock for shared spaces, these devices streamline entry and reduce lost key headaches. Many models support Wi‑Fi, Bluetooth, or Z‑Wave, letting you manage codes remotely, receive alerts, and integrate with smart home platforms like Alexa and Google Home.

Core features include auto‑locking, one‑time or scheduled PIN codes, audit trails, and low battery warnings. Options range from deadbolts that reuse your existing cylinder to electronic mortise locks for higher traffic doors. You can choose keypad, touchscreen, RFID, and many products allow traditional key override for backup.

Choosing the right electronic door lock is easier with a quick checklist:
- Door fit: confirm door thickness, backset, and latch/strike alignment.
- Power: check battery type and life; look for 9V jump ports or USB emergency power.
- Security: ANSI/BHMA Grade 1 or 2 hardware, hardened strikes, and anti‑tamper design.
- Connectivity: local Bluetooth for simple setups, Wi‑Fi for remote control, Z‑Wave or Matter for hubs.
- Privacy and data: app permissions, encryption, and two‑factor authentication.
- Environment: weather rating for exterior doors and keypad visibility in sunlight.

Benefits extend beyond convenience. Hosts can issue temporary access to cleaners and guests, facility managers can monitor entries without rekeying, and homeowners can get notifications the moment family arrives. Many smart locks work with door sensors to verify closed‑door status and trigger automations like lights and cameras.

Popular use cases include apartments, vacation rentals, home offices, garages, and business back doors. Search by finish, cylinder type, and platform compatibility to match your existing hardware and ecosystem, then follow the manufacturer’s installation guide for a secure fit and smooth setup.
