A smart door lock eliminates fumbling for keys, lets you grant temporary access to guests and service providers without physical keys, and logs every entry with a timestamp. The best 2026 models integrate with your smart home platform and never require you to worry about being locked out.
We evaluated security ratings, keypad reliability, Bluetooth and Wi-Fi connectivity, battery life, and installation complexity to find the best smart door locks.
What to Look For
- Security grade: ANSI Grade 1 is the highest residential security rating — the lock can withstand 250,000 cycles, a 6,250-lb dead-bolt shear force, and 75 door strikes. Grade 2 withstands 150,000 cycles. Always choose Grade 1 for exterior doors.
- Entry methods: The best smart locks support keypad code entry, smartphone app, key fob, Apple HomeKit, and physical key as a backup. More entry methods mean fewer lockout scenarios.
- Connectivity: Bluetooth-only locks require your phone to be nearby. Wi-Fi or Z-Wave enabled locks allow remote locking, unlocking, and monitoring from anywhere. A hub or bridge extends Bluetooth locks to Wi-Fi capability.
- Battery life: Most smart locks run on AA batteries lasting 6-12 months. Auto-lock and high-frequency Bluetooth scanning drain batteries faster. Low battery alerts via app are essential.
- Installation complexity: Most smart locks replace the interior portion of your existing deadbolt — installation takes 15-30 minutes with a screwdriver. Some require professional installation or a specific existing deadbolt model to be compatible.

Frequently Asked Questions
What is the best smart door lock?
The Schlage Encode Plus is our top pick. ANSI Grade 1 security, built-in Wi-Fi, Apple Home Key support, and 100 access codes make it the most capable residential smart lock available. For renters who cannot replace existing hardware, the August Wi-Fi 4th Gen is the best retrofit option.
Are smart locks safe?
ANSI Grade 1 smart locks from reputable brands (Schlage, Yale, August) are as secure as traditional deadbolts against physical attacks. The primary security difference is digital — ensure you use a strong, unique PIN and keep the lock's firmware updated. Avoid brands without ANSI certification or clear security audit history.
How long do smart lock batteries last?
Most smart locks run for 6-12 months on standard AA batteries depending on Bluetooth and Wi-Fi scan frequency, temperature, and how often the lock actuates. Auto-lock and frequent remote checks drain batteries faster. All quality smart locks send low battery alerts through the app well before the batteries actually die.
