A smart lock is an electronic door lock that allows users to lock and unlock a door using methods such as a keypad, smartphone app, Bluetooth, Wi-Fi, fingerprint, or other authorized access methods. Many smart locks also retain a traditional keyway for mechanical entry.
Unlike a conventional lock that relies primarily on a physical key, a smart lock combines mechanical locking hardware with electronic access control. Depending on the model, users may also be able to create access codes, manage users, receive notifications, or control the lock remotely.
How Does a Smart Lock Work?
A smart lock uses an electronic control system to operate the lock mechanism. When an authorized code, phone, credential, or other access method is recognized, an internal motor or electronic mechanism allows the lock to lock or unlock.
Smart locks can communicate using different technologies, including:
-
Bluetooth
-
Wi-Fi
-
Z-Wave
-
Matter
-
Keypads
-
Fingerprint sensors
-
Mobile applications
The features depend on the specific lock. Some models communicate directly with a phone, while others connect to a home automation hub or Wi-Fi network. Schlage, for example, currently offers smart locks with Wi-Fi, Matter, Z-Wave, and app-based control depending on the model.
What Is a Smart Lock Used For?
Smart locks are commonly used for residential and light commercial access control. They can provide:
-
Keyless entry
-
PIN-code access
-
Smartphone-controlled locking
-
Remote locking and unlocking
-
Temporary access codes
-
Guest access
-
Access notifications
-
Automatic locking
-
Smart-home integration
These features can be useful for homeowners, families, rental properties, offices, and other locations where managing multiple users is important.
Types of Smart Locks
Smart locks come in several configurations.
Keypad Smart Locks
Keypad locks allow users to enter a PIN instead of carrying a traditional key. Some models also retain a physical keyway.
Bluetooth Smart Locks
Bluetooth-enabled locks communicate with compatible smartphones or other nearby devices. They are commonly used for local, proximity-based access.
Wi-Fi Smart Locks
Wi-Fi smart locks can connect to a home network, allowing compatible models to provide remote access and monitoring through an app.
Biometric Smart Locks
These locks use biometric identification such as fingerprints to authorize access.
Retrofit Smart Locks
A retrofit smart lock can be installed over or integrated with existing door hardware, depending on the design. This allows some users to add smart functionality without completely replacing the mechanical lock.
What Is a Kwikset Smart Lock?
A Kwikset smart lock is an electronic lock from Kwikset that can provide keyless entry, programmable access codes, and, on compatible models, smart-home connectivity.
Kwikset offers several smart-lock families, and their reset and programming procedures vary by model. For example, Kwikset's official support documentation provides separate factory-reset procedures for different SmartCode, Kevo, Halo, and other smart-lock products.
This means the exact instructions for a Kwikset smart lock should be matched to the specific model rather than applying one reset procedure to every Kwikset lock.
What Is a Schlage Smart Lock?
A Schlage smart lock is an electronic door lock that combines Schlage mechanical hardware with electronic access features.
Current Schlage smart-lock models include products such as Encode, Encode Plus, Arrive, Connect, and Sense Pro. Depending on the model, features can include Wi-Fi connectivity, remote access, smartphone control, Apple Home Key support, voice assistants, Matter, or Z-Wave.
The Schlage Home app can also allow compatible locks to be monitored and controlled remotely, while access codes and other settings can be managed through the app.
How to Reset a Kwikset Smart Lock
Resetting a Kwikset smart lock restores some or all of its settings to their default state. The exact process depends on the model.
For example, Kwikset's official instructions for some SmartCode and Signature Series models involve removing the battery pack, holding the Program button while reinstalling the batteries, and completing the reset sequence. Other Kwikset products use different procedures.
A factory reset can remove user codes and, on connected models, may remove the lock's association with a smart-home system.
Before resetting a Kwikset smart lock:
-
Identify the exact lock model.
-
Keep the door open and unlocked when the manufacturer's instructions require it.
-
Review the model-specific Kwikset instructions.
-
Understand that existing codes or smart-home connections may be deleted.
-
Reconfigure the lock after the reset if necessary.
For Halo, Halo Touch, and Aura models, Kwikset also documents a separate network reset that removes Bluetooth pairings, Wi-Fi settings, and user associations without being identical to every factory-reset procedure.
How Do You Turn Off a Smart Lock?
There is no universal "off" setting for smart locks because different models use different power and control systems.
If you mean temporarily disabling a smart feature, the available options may include turning off automatic locking, disabling remote access, disconnecting the lock from a smart-home network, or removing app-based access. The available settings depend on the manufacturer and model.
For example, compatible Schlage locks provide settings for features such as auto-lock, one-touch locking, Wi-Fi, notifications, and access management through the Schlage Home app.
If you mean completely powering down a battery-operated smart lock, removing its batteries may disable its electronic functions, but this is not necessarily the same as turning off the lock. Always check the manufacturer's instructions before removing power.
What If You Mean Smart Lock on a Phone?
"Smart Lock" can also refer to a smartphone security feature rather than a door lock. In that context, turning off Smart Lock means disabling a device's automatic unlocking or trusted-device functionality, and the steps depend on the phone and operating system.

Are Smart Locks Secure?
Smart-lock security depends on both the mechanical design and the electronic security system.
Important considerations include the quality of the lock hardware, authentication method, encryption, software updates, access-code management, physical installation, and the security of any connected smartphone or home network.
A smart lock should therefore be evaluated as both a physical security device and an electronic access-control system.
What Happens When a Smart Lock Battery Dies?
Most battery-powered smart locks are designed with a low-battery warning or another way to indicate that power is running low.
Depending on the model, a smart lock may also retain a mechanical keyway or provide an external emergency power method. The available backup method varies by product.
Keeping replacement batteries available and paying attention to low-battery warnings can help prevent an unexpected lockout.
Smart Lock vs. Electronic Lock
The terms smart lock and electronic lock are related but do not always mean exactly the same thing.
An electronic lock may simply use an electronic keypad or card reader to control access. A smart lock generally adds connected features such as smartphone control, remote access, smart-home integration, user management, or notifications.
Not every electronic lock is a smart lock, but many smart locks are electronic locks.
How to Choose a Smart Lock
Before choosing a smart lock, consider:
-
Door and lock compatibility
-
Keyway and existing hardware
-
Keypad or smartphone access
-
Wi-Fi or Bluetooth requirements
-
Smart-home compatibility
-
Battery life
-
Backup entry method
-
Number of users
-
Temporary access requirements
-
Remote-access features
-
Installation requirements
Compatibility is particularly important because smart locks are not universally interchangeable with every door or deadbolt.
Why Are Smart Locks Important?
Smart locks give users additional ways to manage access without relying entirely on physical keys. Depending on the model, they can simplify entry for household members, provide temporary access for guests, and allow owners to monitor or manage access through an app.
Their electronic features also make them useful in smart-home and access-control systems.
