Smart homes are becoming more common every year. In 2025, over 68% of smart home owners use some form of voice automation for daily tasks. One of the best upgrades you can make is smart lock automation using voice assistants like Alexa, Google Assistant, and Siri.
The keyitlocks guide explains how voice-controlled smart locks work, how to set them up, safety tips, real stats about the market, and practical use cases. If you want to automate your doors, this post will help you do it safely and easily.
Why smart lock automation matters?
Smart lock automation lets you come and go without lifting a finger, tightening your home routine like the click of a closing door. No more scrambling for keys—just say a quick command, and the door clicks locked or swings open. A lot of people say it’s quicker and simpler—especially when their hands are juggling a warm coffee and a phone.
Smart lock adoption is growing fast. The global smart lock market was estimated at about USD 2.77 billion in 2024 and is projected to grow strongly through the next decade. This growth shows more people trust and want smart lock automation for everyday life.
In the same way, voice assistants are widespread. Millions of people now use voice assistants on speakers and phones — meaning voice-enabled smart locks are a natural fit for modern homes in demand usage.
What is smart lock automation with voice assistants?
Smart lock automation means connecting a smart lock to a voice assistant so you can control the lock by speaking. Examples of voice commands:
- “Alexa, lock the front door.”
- “Hey Google, is the back door locked?”
- “Hey Siri, unlock the main door.”
When set up correctly, voice commands can lock, unlock, check status, and integrate the lock into home routines (for example, locking doors when you say “Goodnight”).
Benefits of smart lock automation
- Enjoy true hands-free ease: no keys jingling, no phone to grab—just step up and get it done.
- Syncs with your home routine:—lock the door, switch off the lights, and arm the alarms in one smooth move.
- Give your family better control:—let trusted household members use voice commands, even from across the kitchen table.
- Quick guest entry: — visitors can use a brief voice command or tap the app to get in.
- Smart home integration: lets your cameras, lights, and sensors work together so your security feels tighter—like the porch light flicking on when motion stirs outside.
Because smart speaker and voice assistant use is increasing, adding smart lock automation creates a smooth, modern home experience based on precedent research .
How to set up smart lock automation
Below are simple steps to connect most smart locks to common voice assistants.
1. Check compatibility
Before buying or installing, check if the lock supports your assistant:
- Alexa (Amazon)
- Google Assistant (Google Home)
- Siri (Apple HomeKit)
If the lock is Matter-compatible or supports HomeKit, it will likely work with multiple assistants.
2. Install the smart lock
Follow the lock maker’s instructions. Most locks fit standard deadbolts and require just a screwdriver and 20–40 minutes.
3. Connect to home network or hub
Your lock could connect through Wi‑Fi, Bluetooth, Zigbee, Z‑Wave, or even a hub tucked beside your router. Be sure your lock connects properly and your home Wi‑Fi’s strong—no weak signal blinking on the router light.
4. Add the lock to the lock app
Install the manufacturer app (for example, the KeyItLocks app or the lock brand app). Add the lock and create a secure account.
5. Link the lock to your voice assistant
| Voice Assistant | Steps to Link Your Smart Lock |
| Amazon Alexa | 1. Open Alexa App → 2. Tap More → Add Device → Smart Home → 3. Select your smart lock brand → 4. Follow setup instructions. |
| Google Home | 1. Open Google Home App → 2. Tap + → Set up device → 3. Choose Works with Google → 4. Search for your lock brand and link it. |
| Apple Home (Siri) | 1. Open the Home App → 2. Tap Add Accessory → 3. Scan the HomeKit code on the lock or packaging → 4. Follow setup instructions. |
6. Test commands
Try commands like: “Lock the front door,” “Is the front door locked?”, and run a routine such as: “Goodnight” → lock doors + turn off lights.
