Smart Locks Explained: What They Do, What to Buy, and How to Install

Smart locks eliminate the need for physical keys and add convenience, security, and remote access to your front door. Here's what to buy and what to know before installing one.

What Smart Locks Actually Offer

• Keypad entry — no keys to lose
• Temporary access codes for guests, cleaners, dog walkers
• Remote lock/unlock from your phone
• Entry logs (see who came and went and when)
• Auto-lock after a set time
• Integration with Alexa, Google, Apple Home

Installation

Most smart locks replace only the interior portion of your existing deadbolt. Installation takes 15-30 minutes with a screwdriver. No wiring required. Battery-powered (typically 6-12 months per set of AA batteries).

Types

Deadbolt Replacement

Replaces the entire lock. Most secure. Compatible with most standard door prep.

Deadbolt Adapter

Security Considerations

Smart locks are not less secure than traditional locks. The keypad is no easier to defeat than a standard lock cylinder. Choose locks with anti-pick, anti-bump, and anti-drill certifications.
