Nuki vs Vivint compares two different security jobs. Nuki starts at one compatible door with smart-lock access, named credentials, and local entry methods. Vivint starts with an installed home-security plan covering quoted sensors, cameras, controls, professional monitoring, and response. A household may choose one or use both, but a lock should not be mistaken for a whole-home alarm.
Short answer: choose Nuki when the main job is controlled entry at a door that passes the hardware and regional fit checks. Choose Vivint when the main job is professionally installed alarm coverage and one service relationship. Use both only after the unlock, entry-delay, disarm, outage, and account-recovery handoffs have been tested.
Nuki vs Vivint at a glance
| Decision area | Nuki | Vivint |
|---|---|---|
| Primary job | Door access and smart-lock control | Installed intrusion, cameras, smart-home control, monitoring, and response |
| Fit gate | Exact door, cylinder or deadbolt, clearance, region, and model | Exact panel, package, sensor map, installation, service address, and agreement |
| Installation | Buyer-led or locksmith-assisted, depending on model and door | Professional installation and service-led setup |
| Users | Owners, residents, guests, cleaners, and temporary access | Owners, residents, installers, monitoring contacts, and emergency contacts |
| Outage question | Which local entry methods survive phone, internet, bridge, and battery failures? | Which alarm, communication, camera, and monitoring paths survive internet and power loss? |
| Best fit | A household solving access at a compatible door | A household buying installed monitored protection |
Start with current first-party records
Use the current Nuki Smart Lock Ultra product record to verify the exact cylinder, installation, battery, connectivity, accessories, platform support, and regional requirements. For Vivint, start with its home-security package record, buying process, and Smart Home getting-started record. Availability, prices, package contents, financing, monitoring, installation, and terms can change. Get the service-address quote and bill of materials in writing.
Compare one property map, not two shopping carts
Write the security jobs before selecting hardware:
- Exterior doors and accessible windows that need direct open-or-closed evidence.
- Interior motion zones, pet routes, sleeping floors, garages, and detached areas.
- Entry methods for owners, children, guests, cleaners, carers, and contractors.
- Camera jobs such as visitor identification, package view, driveway context, and alarm verification.
- Smoke, carbon monoxide, water, freeze, panic, or medical-response requirements.
- The response path: household alerts only or professional monitoring tied to the address.
A Nuki cart can look cheaper because it covers a narrower door-access job. A Vivint quote can look larger because it includes installation, alarm zones, cameras, and ongoing service. Equalize the property map before comparing price.
Nuki door fit comes before app features
Record door handing, cylinder or deadbolt type, door thickness, trim clearance, weather exposure, frame gap, and how freely the lock turns with the door open and closed. A motor should not compensate for a binding bolt or misaligned strike. Confirm the exact Nuki model fits the exact door in the intended market.
- Test the original mechanical entry and emergency-entry method.
- Run ten manual lock cycles before enabling automation.
- List every supported entry method and who receives it.
- Create named, limited credentials instead of one shared permanent code.
- Test scheduled access, revocation, low-battery warning, offline entry, and owner-account recovery.
- Document any bridge, keypad, fingerprint, phone, watch, or network dependency.
Vivint coverage starts with an installed zone map
Ask for the exact panel, communicator, keypad, sensors, cameras, installation scope, monitoring level, contract, financing, cancellation terms, permit duties, and emergency-contact process. After installation, trigger every zone one at a time and match the event name to the written map.
| Layer | Questions to close |
|---|---|
| Perimeter | Which exterior doors, accessible windows, garage entries, and detached areas are direct alarm zones? |
| Interior | Where are motion, glass-break, keypad, panic, and siren devices, and how do pets affect them? |
| Life safety | Which smoke, carbon-monoxide, water, freeze, or medical devices are installed and monitored? |
| Video | What triggers recording, how long is it retained, who can export it, and which plan is required? |
| Response | What is local, app-based, professionally monitored, verified, permitted, and dispatch-eligible? |
Keep unlock and disarm as visible states
An unlocked door can lead into an armed home. A resident may enter before noticing the keypad, location services may be disabled, or an automation may run from the wrong phone. Do not assume that unlocking Nuki disarms Vivint or that the Vivint app can issue Nuki credentials.
- Lock the door and arm the intended Vivint mode.
- Approach with the normal resident phone, then with location services disabled.
- Unlock with the primary method and confirm the actual alarm state.
- Repeat with a backup credential and with internet disconnected under controlled conditions.
- Record entry-delay timing, keypad prompts, alerts, failed actions, and recovery.
The safer default is a separate visible disarm action unless the exact supported handoff, user, phone state, timing, outage behavior, and fallback are documented.
Accounts, privacy, and offboarding
A combined setup may include a Nuki owner, lock administrators, residents, temporary users, a Vivint account owner, secondary users, installers, monitoring contacts, and emergency contacts. Do not merge those roles into one shared login.
| Role | Needed access | Closeout test |
|---|---|---|
| Resident | Daily entry and approved alarm controls | Remove at move-out and prove the old session fails |
| Guest or contractor | Named, time-bounded door access | Expire the credential and confirm no camera or alarm access remains |
| Emergency contact | Response instructions and current phone number | Confirm the address, order, and escalation path |
| Installer or support | Time-bounded setup and troubleshooting | Remove standing access after acceptance |
| Owner | Billing, recovery, users, devices, and service decisions | Test recovery without relying on one unavailable phone |
List who can view lock activity, alarm history, live video, recordings, audio, exports, monitoring records, and dispatch notes. Use the smallest camera field of view that supports the stated job. Remove former users from each record separately.
Internet, power, battery, and service failures
| Failure | Nuki question | Vivint question | Pass condition |
|---|---|---|---|
| Internet offline | Which local entry methods remain? | Which alarm, communicator, camera, and monitoring paths remain? | Household knows what is unavailable and how to respond |
| Phone unavailable | Can an approved person enter without the owner’s phone? | Can an approved person arm, disarm, and answer an event? | Backup control works without sharing an owner login |
| Power offline | Which bridge, keypad, or network functions stop? | Which panel, communicator, camera, router, and service paths have backup? | Backup duration and warnings match the written plan |
| Low lock battery | Who receives and acts on the warning? | Does the alarm report the door state independently? | Battery is replaced before access becomes uncertain |
| Owner unavailable | Who can recover lock administration? | Who can manage billing, contacts, permits, and service? | Approved recovery succeeds without one shared password |
Compare equal 36-month cost
Build three written totals: Nuki only, Vivint only, and both together.
- Nuki: exact lock, cylinder or door work, keypad or other accessory, bridge where required, batteries, backup entry, installation, and replacement allowance.
- Vivint: exact equipment, installation, activation, monitoring, video and selected services, financing, taxes and fees, permits, batteries, maintenance, contract term, renewal, cancellation exposure, and ownership terms.
- Combined: both systems plus any supported connector, duplicated hardware, network and power backup, and the labor needed to test and maintain the handoff.
Separate promotional months from the normal term. A lower first invoice does not prove a lower three-year cost.
Who should choose each path?
Choose Nuki first when
- the first job is controlled entry at one compatible door;
- named credentials and offline entry matter more than whole-home alarm coverage;
- the home already has a separate alarm plan; and
- door fit, region, and recovery methods are confirmed.
Choose Vivint first when
- the first job is installed intrusion, life-safety, camera, and response coverage;
- the household wants professional monitoring tied to the address;
- zone names, contacts, permits, and service ownership are ready to be managed; and
- the complete quote and agreement have been checked.
Use both when
- Nuki has a clear door-access job and Vivint has a separate alarm-response job;
- residents can see and recover both states;
- unlock and disarm have been tested through failures;
- account owners and offboarding are documented; and
- the combined 36-month cost is acceptable.
Run a 90-minute acceptance test
- Minutes 0-10: verify the exact door, Nuki model, Vivint panel, quote, account owner, service address, and written terms.
- Minutes 10-20: run ten manual door cycles and correct binding before automation.
- Minutes 20-30: test every approved Nuki entry method and one expired test credential.
- Minutes 30-40: trigger every Vivint door, window, motion, and panic zone individually.
- Minutes 40-50: test the unlock-to-disarm handoff with normal, disabled-location, and backup entry paths.
- Minutes 50-60: disconnect internet under controlled conditions and record local entry, alarm, communication, video, and recovery.
- Minutes 60-70: run the safe power and low-battery checks supported by the installed equipment.
- Minutes 70-80: add and remove a test user from both systems; prove all old access is gone.
- Minutes 80-90: save the device list, zone map, contacts, account owners, backup entry, outage notes, costs, and next test date.
Do not approve the setup until these blockers are cleared
- The Nuki model, door, cylinder or deadbolt, region, and emergency entry are not confirmed.
- The Vivint bill of materials, monitoring scope, financing, term, renewal, and cancellation language are not in writing.
- Unlock and disarm behavior is assumed rather than tested.
- One unavailable phone or owner account can block entry or recovery.
- Former users, installers, or contractors retain access.
- The internet and power test has no documented response path.

Verdict
Nuki is the focused choice for compatible-door access. Vivint is the broader installed choice for alarm coverage, cameras, monitoring, and response. They are not substitutes. Choose by the first security job and combine them only when the household can see, test, and recover the handoff.
