What is a smart door lock?

A smart door lock is an electronically controlled lock that can be opened or closed using a smartphone app, PIN code, biometric (fingerprint), RFID card, or voice command eliminating the need for traditional keys. It can be monitored and managed remotely.

Types of Smart Door Locks

  • Deadbolt Smart Locks: Replace traditional deadbolts; most common type.
  • Smart Lever Locks: Handle-based locks with smart features.
  • Mortise Smart Locks: Built into the door frame; common in Indian apartments.
  • Biometric Locks: Use fingerprint recognition for keyless entry.
  • Padlocks & Cabinet Locks: Smart versions for gates and storage rooms.

Key Features

  • Remote lock/unlock via smartphone from anywhere.
  • Temporary access codes for maids, guests, or delivery personnel.
  • Auto-lock when door is left open for a set duration.
  • Activity log showing who entered and when.
  • Integration with smart home platforms (Alexa, Google Home).

Smart door locks offer a significant upgrade in home security and convenience. They are especially useful for families, rental properties, and homes with domestic staff requiring limited access.
