6 Best Alternatives to the NUKI Retrofit Smart Deadbolt (2026)
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The Nuki Retrofit Smart Deadbolt is a compact, silver lock that mounts inside your door over an existing deadbolt. It connects via Wi-Fi and supports Matter over Thread for reliable smart home integration. If you are looking for nuki smart lock alternatives, you might need different specs or a larger footprint. The Nuki is small and round, measuring just 2.24 inches wide. Other options offer video, fingerprints, or full handle replacements. Some buyers prefer a black finish or a touchscreen interface. These alternatives were chosen because their core specs overlap with the original, such as Wi-Fi connectivity and app control. They cover different entry methods like keypads or biometric scanners. You might want a device with a built-in camera for visual verification. Or you may need a lock that includes a new handle for older doors. Each option on this list of 6 picks addresses a specific gap in the Nuki design. We focused on practical differences like size, power source, and access methods. This helps you find a lock that fits your door and your security needs without extra drilling or complex setup.
How alternatives compare to Nuki
Anybell Smart Deadbolt with 2K Camera
The Anybell DK86 integrates a 2K camera directly into the deadbolt, offering video verification that the compact Nuki lock lacks. You get fingerprint and app access, plus auto-lock features, all in a larger, black unit measuring 12 inches tall. This is a full replacement, not a retrofit, so you must drill new holes. It suits front doors with strong Wi-Fi signals where you want visual confirmation of visitors. The Nuki remains invisible from the outside and mounts over your existing deadbolt in minutes. Choose the Anybell if you prioritize video security and biometric entry over a low-profile, non-invasive installation.
Kwikset Halo Touchscreen Wi-Fi Deadbolt
The Kwikset Halo Touchscreen is a full deadbolt replacement with a matte black finish, contrasting with Nuki’s silver, interior-only design. It features a touchscreen keypad for guest codes, offering high capacity for visitors without relying on fingerprints or app-only access. The unit is heavier at 3.6 pounds and measures 9.74 inches tall. It connects via Wi-Fi and supports voice control, similar to Nuki’s smart home compatibility. You trade the Nuki’s quick, no-drill retrofit installation for a more robust, traditional deadbolt structure. Pick this if you need extensive guest code management and prefer a visible, touchscreen interface over a hidden smart add-on.
SwitchBot Lock Vision Pro Smart Deadbolt
The SwitchBot Lock Vision Pro supports Matter and direct Wi-Fi, matching Nuki’s connectivity standards while adding fingerprint access. It features auto-locking and works with Alexa and Google Assistant. The unit is matte black and weighs 1.21 pounds, making it lighter than the Kwikset but bulkier than the Nuki’s compact form. It is designed for contactless entry and integrates seamlessly into smart home setups without a hub. Unlike the Nuki, which mounts over an existing deadbolt, this lock replaces the mechanism. Choose this if you want Matter compatibility and biometric entry in a sleek, modern design that prioritizes direct network connection.
Sifely S WiFi Fingerprint Lock
The Sifely S WiFi Fingerprint Lock includes a handle, making it a complete package rather than a retrofit add-on like the Nuki. It offers keypad, fingerprint, and app control, providing more access methods than the Nuki’s app and auto-unlock focus. The black unit connects via Wi-Fi for remote access without a gateway, similar to Nuki’s direct connection. It supports Alexa and Google Assistant for voice control. The design is larger, measuring 7 inches in length, compared to Nuki’s compact 2.24-inch width. Select this if you want a full door handle set with rapid biometric entry and direct Wi-Fi control, rather than a small device mounted inside your door.
TCL Wi-Fi Touchscreen Smart Deadbolt
The TCL D2 Plus Smart Deadbolt features a touchscreen, keypad, and fingerprint scanner, offering more access options than the Nuki’s app-centric approach. It connects via Wi-Fi and supports Alexa and Google Assistant, matching Nuki’s smart home integration. The dark grey unit is battery-powered and weighs 2.05 pounds. It is designed for direct Wi-Fi setup, simplifying installation for renters or homeowners. Unlike the Nuki’s compact, invisible design, the TCL is a full deadbolt replacement with a visible interface. Choose this if you prioritize high user code capacity and multiple entry methods, including touchscreens, over a low-profile retrofit solution.
Sifely Keypad Smart Deadbolt
The Sifely Keypad Smart Deadbolt is tailored for rental properties, offering high passcode capacity and physical fob options that the Nuki does not mention. It connects via Wi-Fi and supports Alexa and Google Assistant, providing similar smart home integration. The silver unit features auto-locking and weighs 2 pounds. It is a full deadbolt replacement, unlike the Nuki’s interior retrofit design. The keypad and fingerprint access offer more entry methods than the Nuki’s app and key backup. Pick this if you manage rental properties and need robust guest code management and physical fob support, rather than a compact, invisible smart lock add-on.
