The Four Best Smart Door Locks

Our Winner: August Wi-Fi Smart Lock (4th gen)

August Wi-Fi Smart Lock (4th gen) is the winner for most smart door locks shoppers because it combines the strongest all-around performance with the fewest compromises. If your priorities are different, the Best Value, Best Premium, and specialty picks below make the decision easier rather than forcing every buyer into one recommendation.

1. August Wi-Fi Smart Lock (4th gen): Best Overall

August Wi-Fi Smart Lock (4th gen) earns its place in this smart door locks comparison by balancing practical performance with the expectations buyers bring to this price tier. At $249–$279, it is positioned for shoppers who want a clear reason to choose one model rather than simply buying the most expensive option. The useful question is whether its feature set matches your routine, space, and tolerance for compromise.

The strongest case for this pick is straightforward: Auto-unlock uses geofencing and BLE to unlock when you approach your door; DoorSense tells you if your door is closed and locked — not just assumed; Retrofit design attaches to your existing deadbolt interior — exterior key stays the same. Those advantages matter in everyday ownership because they affect setup time, consistency, comfort, and how often the product gets used. A product that performs predictably is usually a better long-term purchase than one with a longer specification sheet but a frustrating workflow.

The trade-offs deserve equal attention. Retrofit adds ~0.75 in to the interior side — check door clearance; CR123 batteries harder to find than AA — stock up on Amazon. These are not automatic deal-breakers, but they should shape the buyer decision. Choose August Wi-Fi Smart Lock (4th gen) when its strengths map directly to your highest-priority use case, and compare the next product when a limitation would affect every session.

2. Schlage Encode Plus: Best for Apple Home

Schlage Encode Plus earns its place in this smart door locks comparison by balancing practical performance with the expectations buyers bring to this price tier. At $279–$299, it is positioned for shoppers who want a clear reason to choose one model rather than simply buying the most expensive option. The useful question is whether its feature set matches your routine, space, and tolerance for compromise.

The strongest case for this pick is straightforward: Fingerprint reader unlocks in under a second — no phone or code needed; HomeKit compatibility works without an internet connection for local automations; Matter support means it works with Alexa, Google, and Apple simultaneously. Those advantages matter in everyday ownership because they affect setup time, consistency, comfort, and how often the product gets used. A product that performs predictably is usually a better long-term purchase than one with a longer specification sheet but a frustrating workflow.

The trade-offs deserve equal attention. Larger interior unit may not fit tight door frames; App UX is less polished than August. These are not automatic deal-breakers, but they should shape the buyer decision. Choose Schlage Encode Plus when its strengths map directly to your highest-priority use case, and compare the next product when a limitation would affect every session.

3. Yale Assure Lock 2: Best Display

Yale Assure Lock 2 earns its place in this smart door locks comparison by balancing practical performance with the expectations buyers bring to this price tier. At $219–$249, it is positioned for shoppers who want a clear reason to choose one model rather than simply buying the most expensive option. The useful question is whether its feature set matches your routine, space, and tolerance for compromise.

The strongest case for this pick is straightforward: OLED status display shows lock status, battery level, and connected users at a glance; 12-month battery life is the longest in the category; Yale app consistently rated higher than competitors for reliability. Those advantages matter in everyday ownership because they affect setup time, consistency, comfort, and how often the product gets used. A product that performs predictably is usually a better long-term purchase than one with a longer specification sheet but a frustrating workflow.

The trade-offs deserve equal attention. No built-in NFC card/tag support — keypad only for non-phone entry; Fingerprint reader only on premium model ($249) — base model is keypad only. These are not automatic deal-breakers, but they should shape the buyer decision. Choose Yale Assure Lock 2 when its strengths map directly to your highest-priority use case, and compare the next product when a limitation would affect every session.

4. Kwikset Halo Touch: Best Budget

Kwikset Halo Touch earns its place in this smart door locks comparison by balancing practical performance with the expectations buyers bring to this price tier. At $149–$179, it is positioned for shoppers who want a clear reason to choose one model rather than simply buying the most expensive option. The useful question is whether its feature set matches your routine, space, and tolerance for compromise.

The strongest case for this pick is straightforward: 100-fingerprint capacity handles large households and small businesses; Under $180 for fingerprint + keypad + WiFi — best value combo; Fingerprint unlocks in under a second with no reach for a phone. Those advantages matter in everyday ownership because they affect setup time, consistency, comfort, and how often the product gets used. A product that performs predictably is usually a better long-term purchase than one with a longer specification sheet but a frustrating workflow.

The trade-offs deserve equal attention. No auto-unlock — requires deliberate unlock action every time; Kwikset app rated lower than August and Yale for reliability. These are not automatic deal-breakers, but they should shape the buyer decision. Choose Kwikset Halo Touch when its strengths map directly to your highest-priority use case, and compare the next product when a limitation would affect every session.

How did we choose the four best smart door locks?

We compared the products on price, core specifications, practical ownership, warranty expectations, buyer feedback signals, and the specific use case each model serves. The first product is the overall winner, but the other three remain strong choices when their badge matches your priorities.

Which smart door locks are best for a budget buyer?

Start with the product carrying the Best Value badge and compare its first two specifications with the premium picks. A lower price is useful only when it still covers the features you will use, so treat the comparison table and the product trade-offs as a pair.

Are the Amazon prices guaranteed?

No. Amazon prices, availability, seller offers, and delivery dates can change. The price ranges on this page are editorial guidance; use the linked Amazon listing to confirm the current price and return policy before ordering.

Which product is the winner?

August Wi-Fi Smart Lock (4th gen) is our winner because it offers the strongest overall balance of performance, useful specifications, and ownership value for most shoppers. Buyers with a narrower need may prefer another badge in the lineup.
