Eufy vs Nuki: Which Fingerprint Door Lock Is Better?
Both Eufy and Nuki are established names in the smart home security space, but they approach fingerprint door locks from different angles. Eufy focuses on all-in-one convenience with a built-in fingerprint reader and video doorbell, while Nuki prioritises modularity and broad smart home compatibility.
We compared owner reviews, published specs, and brand reliability to break down the key differences. Below, we cover installation, battery performance, security features, and ecosystem support to help you decide.
Installation and Compatibility
Eufy's Video Smart Lock (S330) replaces your entire deadbolt assembly, which means you need a compatible door prep (standard bore hole). It works with most US deadbolts but requires more involved installation. Nuki's Smart Lock Pro mounts over your existing lock, making it ideal for renters or those who want a quick setup.
Nuki also offers a wider range of accessories, including a keypad with fingerprint reader, a bridge for remote access, and a door sensor. Eufy integrates the fingerprint reader and camera into the lock body, so you get fewer components but less flexibility.
Battery Life and Power Management
Battery life is a critical factor for smart locks. Eufy uses a built-in rechargeable battery that lasts 4-6 months depending on usage and video streaming. Nuki runs on four AA batteries that last 6-9 months, with a low-battery warning sent to your phone.
Nuki's advantage is that you can swap batteries instantly without removing the lock, while Eufy requires you to take the lock off to recharge. Owner reviews on both brands report reliable battery life, but Nuki edges ahead for convenience.
Fingerprint Reader Performance
Eufy's fingerprint reader is embedded in the lock body and supports up to 50 fingerprints. It uses a capacitive sensor that is fast and accurate, with most owners reporting a 95% success rate. Nuki's fingerprint reader is optional and comes via the Keypad 2, which also includes a keypad and fob support.
If fingerprint access is your priority, Eufy offers a more seamless experience because the reader is always available on the lock. Nuki's solution works well but adds an extra accessory and cost.
Smart Home Ecosystem and Matter Support
Nuki is a leader in smart home integration. The Smart Lock Pro supports Matter, making it compatible with Apple Home, Amazon Alexa, Google Home, and Samsung SmartThings out of the box. Eufy works with Apple Home, Alexa, and Google, but does not support Matter.
For users with mixed smart home hubs, Nuki's Matter support is a significant advantage. Eufy's ecosystem is solid but more limited, especially for advanced automations.
Security and Build Quality
Both locks are built with robust materials. Eufy uses a zinc alloy body with a hardened steel deadbolt, rated for 500,000 cycles. Nuki uses a brushed aluminium design with a torque of 1.2 Nm, sufficient for most standard doors.
Eufy includes a built-in camera (2K resolution) that records events and acts as a doorbell, adding an extra layer of security. Nuki focuses on lock security with encrypted communication and auto-lock/unlock via geofencing. Both brands have strong reliability records, but Eufy's integrated camera gives it an edge for those wanting video monitoring.
What to Check Before Buying a Fingerprint Door Lock
- Door compatibility: Measure your door thickness (standard 1.375 to 1.75 inches) and check the backset (2-3/8 or 2-3/4 inches).
- Existing lock type: Nuki works with most single-cylinder deadbolts; Eufy requires a full replacement.
- Smart home hub: Ensure the lock supports your preferred platform (Apple Home, Alexa, Google).
- Battery backup: Look for a physical key override or USB-C backup in case of power loss.
- Fingerprint capacity: Check how many fingerprints the lock can store (Eufy: 50, Nuki: 100 via keypad).
Mistakes to Avoid
- Skipping door prep: Not all doors have the correct bore hole for Eufy; measure twice before buying.
- Ignoring battery life: Video streaming drains batteries faster; consider a lock without video if you want longer intervals.
- Overlooking Matter support: If you plan to expand your smart home, Matter compatibility future-proofs your lock.
- Forgetting about guest access: Both locks offer temporary codes, but Nuki's app is more flexible for scheduling.
Nuki Smart Lock Pro (3rd Gen)
Best for smart home integration and retrofit ease.
Eufy Security Video Smart Lock (S330)
Best For Integrated VideoPros
- Built-in fingerprint reader
- 2K video doorbell included
- Rechargeable battery
Cons
- Shorter battery life with video
- No Matter support
The Eufy S330 is an all-in-one solution that combines a smart lock, fingerprint reader, and 2K video doorbell. It is easy to use with the Eufy app and supports Apple Home, Alexa, and Google. The fingerprint sensor is fast and accurate, and the video quality is good for monitoring visitors.
However, the battery life is shorter than Nuki's due to video streaming, and installation requires replacing your existing deadbolt. Owner reviews note that the lock works best on standard US doors, and the lack of Matter support limits future smart home expansion.
Nuki Smart Lock Pro (3rd Gen)
Best For Smart Home HubsPros
- Matter support for all hubs
- Easy retrofit installation
- Long battery life
Cons
- Fingerprint reader sold separately
- No built-in camera
The Nuki Smart Lock Pro is the most versatile smart lock for users with multiple smart home platforms. Its Matter support ensures compatibility with Apple Home, Alexa, Google, and SmartThings. The retrofit design mounts over your existing deadbolt, making it ideal for renters.
Battery life is excellent at 6-9 months, and the app is well-regarded for its scheduling and geofencing features. The main downside is that the fingerprint reader requires the separate Keypad 2, adding to the cost. Owner reviews praise its reliability and ease of use.
Eufy Smart Lock Touch (T8520)
Best Budget Fingerprint LockPros
- Affordable price
- Good battery life
- Built-in fingerprint reader
Cons
- No Matter support
- No video doorbell
The Eufy Smart Lock Touch is a more affordable alternative to the S330, offering a built-in fingerprint reader without the video doorbell. It runs on AA batteries and lasts 8-10 months, which is better than the S330. The lock supports Alexa and Google, but not Apple Home.
Owner reviews highlight its reliable fingerprint sensor and easy installation, though it requires replacing your deadbolt. It is a solid choice if you want fingerprint access without paying for video features.
Nuki Smart Lock (2nd Gen)
Best Budget NukiPros
- Lower price than Pro
- Retrofit installation
- Good app features
Cons
- No Matter support
- Fingerprint reader sold separately
The Nuki Smart Lock (2nd Gen) is a more affordable entry point into the Nuki ecosystem. It retains the retrofit design and long battery life of the Pro but lacks Matter support. It works with Alexa, Google, and HomeKit via the Nuki Bridge.
Owner reviews note that it is reliable and easy to install, but the lack of Matter may be a dealbreaker for future-proofing. The fingerprint reader is still an optional add-on, so factor that into the total cost.
Eufy Security Smart Lock (T8500)
Best For Apple HomeKitPros
- Apple HomeKit support
- Built-in fingerprint reader
- Good battery life
Cons
- No video doorbell
- No Matter support
The Eufy Smart Lock (T8500) is similar to the T8520 but adds native Apple HomeKit support, making it a good choice for Apple users. It has a built-in fingerprint reader and runs on AA batteries for 8-10 months. The lock is easy to install and works with the Eufy app.
Owner reviews appreciate the HomeKit integration and reliable fingerprint sensor, but note that the lock lacks Matter support and does not include a video doorbell. It is a solid mid-range option for those in the Apple ecosystem.
