First confirm that your exact doorbell and lock models support the action you want. A shared brand, “Works with” badge, or Matter compatibility does not by itself mean a doorbell can trigger a lock. Check the manufacturers’ current model, firmware, regional, and hub requirements; then pair the devices and test every action while you are home. For security, prefer a doorbell notification followed by a deliberate unlock over unlocking automatically when someone rings.
Check compatibility before you buy or pair
Write down each device’s exact model, hardware revision if applicable, firmware version, app, and country or region. On the manufacturers’ current support pages, look for the specific doorbell-to-lock function—not just general compatibility. Notification, live video, lock status, remote unlocking, voice control, and automation are separate capabilities.

There are two common routes. A direct manufacturer integration links devices through the maker’s app or account. A shared platform or Matter setup connects accessories through a smart-home ecosystem. The latter may expose lock controls without allowing a doorbell event to control that lock. Verify the exact action and any hub requirement before relying on it.

- Aqara U100 and Video Doorbell G4: Aqara describes viewing a visitor and unlocking the U100 after a doorbell press. The U100 also lists Apple Home/Home Key and Matter-related compatibility, with hub requirements for some features. See Aqara Smart Lock U100 and Aqara Video Doorbell G4 for the current feature details.
- Selected TP-Link Tapo locks and doorbells: TP-Link documents unlocking from a supported doorbell’s Live View or Video Call page and synchronized notifications. The supported models and firmware are specific, and the list can change; check TP-Link’s support guide before pairing.
- eufy C34/E30 through a Matter ecosystem: eufy’s guide requires a compatible Matter hub in the selected Apple, Alexa, or Google ecosystem. It describes adding the lock to that ecosystem; it does not establish that a doorbell can trigger the lock. See eufy’s Matter setup guide.
Apple says HomeKit accessory communication is authenticated and encrypted, and documents certificate-based identity and encrypted sessions for Matter accessories in Apple homes. That is platform-security context, not a guarantee that a particular doorbell and lock interoperate. Check Apple’s platform security documentation alongside the device makers’ compatibility information.

Set up the devices in a safe order
- Confirm the lock fits and keep a fallback. Follow the chosen lock’s installation guide for your door and deadbolt. Retain the physical key or other fallback provided by the manufacturer, and finish the lock’s standalone setup before adding integrations.
- Secure the router and accounts. Change default router administrator credentials, use Wi-Fi encryption, install router updates, and give each account a unique password. Enable two-factor authentication where available. Consider a separate guest or IoT network if your router supports it, but test device discovery and platform functions after moving devices. The FTC’s home Wi-Fi guidance and smart-home security guidance offer practical steps; NIST also discusses separate networks in its IoT cybersecurity resources.
- Complete native setup first. Add the lock and doorbell to their own manufacturer apps, install available updates, configure household members and access codes, and review camera, audio, and cloud privacy settings. FTC guidance recommends applying device and app updates and using available security features.
- Meet the chosen integration’s requirements. For direct pairing, follow the maker’s current in-app instructions. For a platform or Matter route, confirm the selected hub supports both devices and that the lock functions you need are exposed through that route. Do not assume that adding a lock to Apple Home, Alexa, or Google Home creates a doorbell-to-lock action.
- Pair and test while physically present. Follow the app’s on-screen pairing steps. Test a doorbell press, video or notification, lock status, the intended unlock control, and your physical fallback. Check what happens if internet access or the manufacturer’s cloud is unavailable; an online integration may stop working. TP-Link states that its documented doorbell integration does not support local-only mode.
- Limit access after setup. Give app access only to people who need it, remove former household members, protect access codes, and review sign-in or activity controls if offered. Turn off remote-management or voice features the household will not use.
Make unlocking intentional
A doorbell ring is not proof that the person outside should enter. The safer default is to receive a notification, identify the visitor, and unlock deliberately only when appropriate. Avoid automations that unlock solely because someone rang or appeared on camera.
Check what your exact setup permits: some combinations may offer an unlock button from live view, while others may provide only notifications or lock status. Voice unlocking is not universal. For example, SimpliSafe says its Alexa and Google Assistant integrations can arm its system in a way that causes automatic locking, but voice unlocking is unavailable for security reasons. See SimpliSafe’s voice-assistant support page.

Keep the setup secure over time
- Apply updates and verify they took. Keep phone apps and device firmware current, and enable automatic updates where available. In a 2020 study involving 40 smart-home users, NIST found inconsistent update transparency and confusion about whether updates had been applied. Check the device app or manufacturer support page rather than assuming an update completed.
- Review users and privacy. Periodically remove people who no longer need access, review codes and household sharing, and check video/audio retention, cloud access, and notification settings. Disable features you do not use.
- Reassess support status. A 2022 NIST survey of 412 smart-home users examined consumer perspectives on loss of manufacturer support; unsupported devices may remain connected when users are not alerted or do not understand the consequences. If support ends, assess whether to replace or retire the device rather than assuming it will remain safe indefinitely. See NIST’s summary of the 2022 study.
- Reset devices when moving into a home. Remove previous administrative access and personal data, factory-reset inherited devices, create new accounts, and check for updates. See FTC advice on using smart-home devices safely.
