Best Smart Locks with Voice Control
Voice control turns a smart lock from a convenience into something you can genuinely use hands-free, whether you are juggling groceries at the front door or checking that everything is locked from bed. The catch is that not every smart lock plays equally well with Alexa, Google Assistant, and Apple Home, and the lock hardware itself still has to fit your door and your security needs. This guide ranks real, currently sold locks by how well they combine reliable voice control with solid day to day performance.
Quick answer
The August Wi-Fi Smart Lock (4th Gen) is our top pick for most homes because it works with Alexa, Google Assistant, and Siri, and it fits over your existing deadbolt without replacing keys.

What Matters Most for This Category
The single biggest factor is which voice ecosystem you actually use. Alexa and Google Assistant support is broad, but Apple Home (HomeKit) support is much narrower, so iPhone households should check that box first. After that, decide between a retrofit lock that keeps your existing keys and deadbolt, and a full replacement that swaps the whole lock. Retrofit models are easier to install and renter friendly, while full replacements often add keypad entry, auto lock, and a cleaner look. Finally, confirm whether the lock needs a separate hub or Wi-Fi bridge for remote access and voice control, since that changes both the price and the setup.

Entry levelPros
- Fingerprint unlock and keypad included
- Rechargeable battery instead of disposables
- Lower entry price than most competitors
Cons
- Needs the separate Wi-Fi bridge for voice control and remote access
- No Apple Home support

Voice control through Alexa and Google Assistant requires the separate Eufy Wi-Fi bridge. Based on manufacturer specifications, it stores multiple fingerprints and supports app based management.
Who Should Avoid the Top Pick
Skip voice controlled smart locks if you rent and cannot modify the deadbolt, since most full replacements require landlord approval. Also avoid them if your Wi-Fi is unreliable at the front door, because remote voice control depends on a stable connection. Households that want zero app or account setup should stick with a traditional keyed deadbolt.
Before You Buy
Measure your door thickness and backset before ordering, and confirm whether your existing deadbolt can be retrofitted or must be fully replaced. Check which voice assistants you actually use, and note whether the lock needs a separate hub or bridge for Wi-Fi features. Finally, decide how you want to handle batteries, since rechargeable and disposable options differ in long term cost and convenience.
FAQs
Do smart locks with voice control need a hub?
Some do and some do not. Locks with built-in Wi-Fi like the August Wi-Fi Smart Lock and Schlage Encode Plus work without a hub, while others such as the Eufy Smart Lock Touch need a separate bridge for remote voice control.
Can I use voice control to unlock my door?
Most brands allow voice locking freely but restrict voice unlocking for security, often requiring a PIN or app confirmation. Check the specific assistant and lock combination before relying on voice unlock.
Which voice assistants are most widely supported?
Alexa and Google Assistant have the broadest smart lock support. Apple Home (Siri) support is narrower, so iPhone households should verify HomeKit compatibility before buying.
Will a smart lock work with my existing deadbolt?
Retrofit locks like the August Wi-Fi Smart Lock install over your existing deadbolt and keep your keys. Full replacement locks such as the Schlage Encode Plus swap the entire deadbolt and require more installation work.
How long do smart lock batteries last?
It varies widely by model and usage. Wi-Fi heavy locks tend to drain faster, while Bluetooth only locks can last much longer. Rechargeable models trade disposable battery cost for periodic charging.
Are smart locks as secure as regular deadbolts?
A quality smart lock from a major brand can match or exceed a standard deadbolt, especially models with an ANSI Grade 1 rating. Security also depends on correct installation and keeping firmware updated.
Our verdict
For most homes, the August Wi-Fi Smart Lock (4th Gen) is the best balance of voice assistant support, easy installation, and no extra hub. If you are deep in the Apple ecosystem, the Schlage Encode Plus is worth the higher price for HomeKit and Thread support. Budget buyers who do not need Apple Home should look at the Ultraloq U-Bolt Pro WiFi or the Eufy Smart Lock Touch.
