Nuki Padlock Review
Nuki, a brand known for its smart door locks, has entered the padlock market with a connected, keyless design. This review evaluates the Nuki Padlock based on published specs, battery performance, and aggregated owner feedback to help you decide if it fits your security needs.
Quick answer
The Nuki Padlock is a solid choice for keyless convenience on sheds, gates, or lockers, but it is not a replacement for a high-security padlock. Its Bluetooth-only connectivity and plastic housing limit its use to low-risk, weather-protected locations.

Who is the Nuki Padlock for?
The Nuki Padlock is designed for users who prioritize convenience over brute-force security. It is best suited for low-risk applications such as securing a garden shed, a locker, a gate, or a tool chest where the risk of physical attack is low. The lock is not intended for high-security use like securing a storage unit or a commercial door.
Performance and Connectivity
The Nuki Padlock connects via Bluetooth 5.2 to the Nuki app on your smartphone. The auto-unlock feature uses geofencing to detect when you approach and automatically opens the lock. Owner reviews on Amazon and other retailers indicate that this feature works well within a range of about 10 meters, but it can be delayed if your phone's Bluetooth is slow to connect. The lock can store up to 50 digital keys, which you can share with family members or guests through the app.
Battery life is rated at 6 to 12 months on a single CR2 battery, depending on usage. The lock provides low-battery warnings via the app, and the battery compartment is accessible without removing the lock from the hasp. However, some owners report that the battery life is closer to 6 months with frequent auto-unlock use.
Build Quality and Weather Resistance
The Nuki Padlock has a zinc alloy shackle and a plastic body. The plastic housing is a significant limitation for security because it can be cut with bolt cutters or a saw. The lock carries an IP54 rating, meaning it is protected against dust and splashing water, but it is not fully waterproof. Owners advise against using it in locations exposed to heavy rain or direct sunlight, as the plastic can degrade over time. The lock is not rated for extreme temperatures, and some users in cold climates report the mechanism sticking in freezing conditions.
Alternatives to the Nuki Padlock
If you need a higher level of physical security, consider a traditional hardened steel padlock from brands like Master Lock or ABUS. For a smart padlock with better weather resistance, the Master Lock Bluetooth Padlock offers a similar app experience with a more robust metal body. For remote access, the eLocker Smart Padlock includes Wi-Fi connectivity and a keypad, though it is more expensive.
