1. What Is a Keyless Smart Lock?

A keyless smart lock is a key-free electronic door lock that uses one or more of these entry methods instead of physical keys:

  • Numeric keypads (enter a PIN code)

  • Smartphone apps (Bluetooth/Wi-Fi unlock)

  • Fingerprint scanners (biometric access)

  • Voice control (via Alexa/Google Assistant)

  • Proximity sensors (auto-unlocks when you approach)

  • RFID/NFC cards/fobs (tap to unlock)

Unlike traditional locks:

  • No risk of lost/misplaced keys

  • Allows remote access control

  • Provides entry logs (who entered and when)

2. How Do Keyless Smart Locks Work?

Core Components

  1. Electronic locking mechanism – Replaces traditional tumblers with a motorized bolt.

  2. Authentication system – Verifies users via codes, fingerprints, or mobile signals.

  3. Connectivity module – Enables remote control via Wi-Fi/Bluetooth/Z-Wave.

Step-by-Step Operation

  1. User requests entry (enters code, scans fingerprint, or uses app).

  2. Lock verifies credentials against stored authorized users.

  3. Motor engages and retracts the bolt if approved.

  4. Access is logged in the system (optional on most models).

Power Source:

  • Most use standard batteries (AA/CR123A) lasting 6-24 months.

  • Some premium models offer rechargeable batteries or hardwired options.
