The vivint smart lock is a keypad deadbolt that Vivint bundles with its professionally installed and monitored security system rather than selling as a standalone gadget you grab off a shelf. Built on Kwikset hardware and tuned to talk directly to the Vivint Smart Hub, it is designed to work as one piece of a larger home-security platform, not as a lock you pair with a random app. That distinction shapes everything about how you buy it, what it costs, and who it is right for.
If you already have or are shopping for Vivint’s alarm system, adding the smart lock is a natural extension. If you just want a lock for your phone, there are cheaper standalone options. Here is how the Vivint lock actually works.
Kwikset Roots With Vivint Software
Vivint’s deadbolt is based on Kwikset’s SmartCode platform, the same reliable mechanical lock body used in many mainstream smart deadbolts. Vivint layers its own firmware and pairing on top so the lock communicates with the Vivint Smart Hub over Z-Wave, a low-power wireless protocol built for home automation. Because it uses Z-Wave rather than Wi-Fi, the lock sips battery and leans on the hub for its internet connection.
The Kwikset heritage brings a genuinely useful feature: SmartKey re-keying. If you lose a physical key or move into a home with an existing lock, you can re-key the cylinder yourself in under a minute with the included tool, no locksmith required. The lock accepts a physical key as backup, a keypad code, or a command from the Vivint app and control panel.
Deep Integration With the Vivint Smart Home System
The reason to choose this lock over a generic model is integration. Because it is part of the Vivint Smart Home system, the deadbolt can trigger and respond to other devices in ways a standalone lock cannot. Disarm the alarm from the touchscreen panel and the front door can unlock in the same action. Unlock the door with your code and the system can disarm, turn on interior lights, and adjust the thermostat as part of a single scene.
Everything is controlled through the Vivint app and the wall-mounted Smart Hub touchscreen. You can create user codes for family members, cleaners, or guests, and the app logs each entry with a name and timestamp. Pair the lock with a Vivint Doorbell Camera Pro and you can see who is at the door and unlock it remotely for them without leaving the couch.
Professional Monitoring Context
The Vivint lock rarely stands alone because Vivint is fundamentally a professionally monitored security company. When you sign up, a technician typically installs and configures the entire system, including the lock, so it is correctly paired to the hub from day one. That professional setup is a selling point for people who do not want to touch a screwdriver, and a drawback for DIY-minded buyers who prefer to install and control their own gear.
Professional monitoring means a Vivint monitoring center watches your alarm 24/7 and can dispatch police, fire, or medical response when a sensor trips. The smart lock feeds into that ecosystem: an unexpected unlock while the system is armed can flag an event. Monitoring plans generally start around $30 to $45 per month, and that recurring fee is the real cost center of a Vivint setup, not the hardware itself.
What the Lock and System Actually Cost
Vivint does not publish rigid list prices the way a retailer does, because pricing is quoted per home and often bundled into a financed equipment package. As a rough guide, the smart lock itself typically adds somewhere in the range of $150 to $180 to your equipment total. The larger cost is the overall system: a starter Vivint package with a hub, a few door and window sensors, and a camera commonly lands between $600 and $1,800 in equipment, frequently financed over 42 or 60 months.
On top of hardware, budget the monthly monitoring fee, which is required to unlock the system’s remote and automation features. Contracts are often tied to the financing term, so read the agreement carefully. When you total equipment plus several years of monitoring, a Vivint system is a premium commitment compared with a $200 standalone smart lock and a self-monitored camera.
Everyday Use and Battery Life
Day to day, the lock behaves like any good keypad deadbolt. Family members punch a code, the bolt motors open, and the app records who came and went. You can set the deadbolt to auto-lock after a delay, and you can push temporary codes to guests that expire on a schedule. The 4 AA batteries in the interior housing generally last 6 to 12 months, and the app warns you well before they run low so you are never caught with a dead lock.
Because control flows through the hub, the lock keeps working locally even if your internet drops; you simply lose remote app control until the connection returns. That local reliability is a real advantage of the Z-Wave design over cloud-only Wi-Fi locks.
Range is another practical consideration. Z-Wave signals reach roughly 100 feet indoors, but walls, brick, and metal appliances shorten that. If your front door sits far from the Smart Hub, Vivint’s other Z-Wave devices act as repeaters, extending the mesh so the lock stays responsive. During install, the technician confirms signal strength, which is one more reason the professional setup exists. The lock also reports its status back to the hub, so the app always shows whether the deadbolt is currently thrown or open, and you can lock a forgotten door from bed or from the office without a second thought.
Installation and Getting Set Up
Vivint typically sends a technician to install the entire system, and the lock is part of that visit. The tech removes your existing deadbolt, fits the Vivint deadbolt into the standard bore, and pairs it to the Smart Hub over Z-Wave before leaving, so you never touch the app configuration. The lock fits standard doors from 1-3/8 to 1-3/4 inches thick with a 2-3/8 or 2-3/4 inch backset, the same dimensions as any common deadbolt, so it drops into the hole your old lock left behind.
The upside of professional install is that the Z-Wave pairing and any troubleshooting fall on Vivint, not you. The downside is scheduling: you wait for an appointment window and, in some cases, pay an installation fee that Vivint may waive during promotions. If you are handy, this hands-on service can feel like paying for something you could do yourself, which is the core tradeoff of the whole Vivint model.
How It Compares to Standalone Smart Locks
Set against a retail lock like the Kwikset Halo, Yale Assure Lock 2, or Schlage Encode, the Vivint deadbolt is mechanically similar but philosophically different. A standalone Kwikset Halo costs around $180 to $230 once, connects to your own Wi-Fi, and has no mandatory monthly fee. The Vivint lock cannot be bought and used on its own network; it only speaks to the Vivint hub and lives inside a monitored plan.
That makes the comparison less about the lock and more about the service. If you want professional monitoring, hands-off setup, and a single app that governs alarm, cameras, thermostat, and locks together, Vivint’s tight integration is the payoff. If you would rather own your hardware outright, self-monitor, and skip recurring fees, a standalone smart lock plus a self-monitored camera delivers similar convenience for far less over five years.
Who Should Choose the Vivint Lock
The Vivint smart lock makes the most sense for homeowners who want a single, professionally installed and monitored security ecosystem where the lock, cameras, sensors, and thermostat all cooperate. If you value hands-off setup, 24/7 monitoring, and tight integration over front-end cost, it delivers. If you are a DIY buyer who wants to control a lock from your own app without a monthly fee, a standalone Kwikset, Yale, or Schlage deadbolt gives you similar hardware for a fraction of the long-term cost. Match the lock to the system, and the Vivint deadbolt earns its place; buy it in isolation, and you are paying for integration you will not use.
