Nuki promo code: €30 off your smart lock

Nuki designs its smart locks for DIY installation in under 30 minutes. No lock replacement is needed: the Smart Lock attaches over your existing lock cylinder on the inside, via a universal mechanical fixing compatible with the vast majority of European locks.

The product ships with all parts needed for installation. The Nuki app (iOS and Android) guides the setup process step by step from your smartphone. Once installed, the lock works both with automatic locking/unlocking via geolocation and with manual control from the app.

The €30 Nuki discount applies across the range. On the Smart Lock Go at €109 (launched March 2025), that's 27% off — the best discount-to-price ratio in the range. On the Smart Lock 3.0 Pro at €249, it's 12%. On the Smart Lock Ultra at €349, it's 8.6%.

A Nuki voucher is especially attractive on the Go or the 3.0 Pro: two models that cover 90% of a household's needs. The Smart Lock Ultra is aimed more at advanced users wanting native Matter compatibility and an ultra-compact format, with no external bridge.

The three main models in the Nuki range:

Verdict: for a household wanting remote access with no extra module, the 3.0 Pro at €249 (less €30 with the Nuki promo code = €219) offers the best balance. The Go is ideal if you don't need remote access.

Nuki ships from Austria (HQ in Graz) across Europe in a few working days for standard delivery. An express option is available on the site subject to availability.

Nuki's return policy follows EU law: 14 days to withdraw from receipt of the product, with no justification required. The return is at the customer's cost except in case of non-conformity. The manufacturer warranty is 2 years across the range.

A Nuki promo code used at order time doesn't affect these timings or the return policy.

The Nuki promo code works as a direct reduction on your basket total. Enter it in the dedicated field at checkout on nuki.io — the €30 discount shows instantly in the summary.

The terms "promo code", "voucher" and "Nuki discount" all refer to the same mechanism. The discount generally applies to Nuki products themselves (locks, Bridge, Keypad, modules) — check for any exclusions, particularly on already-discounted bundles or lower-value accessories. Nuki occasionally runs seasonal promotions (sales, Black Friday) that may or may not stack with a promo code.

The Nuki range goes beyond the smart lock itself:

• Smart Lock (Go, 3.0 Pro, Ultra): the core range, the lock itself
• Nuki Bridge: Wi-Fi module to add remote access to a Smart Lock Go (€49)
• Nuki Keypad: numeric keypad to unlock without a smartphone (€79 to €99 by model)
• Nuki Door Sensor: door-state sensor (open/closed) integrated into the app

A €30 Nuki voucher generally applies to the main products. For a complete system (Smart Lock Go + Bridge + Keypad), the promo code can represent up to 12% off the basket total.

Nuki is an Austrian company founded in 2014, now the European reference for smart locks. Its technical strengths:

• Up to 200 virtual keys manageable from the app
• Auto Unlock: automatic unlocking based on your smartphone's geolocation
• Time scheduling: planned locking/unlocking (useful for short-term rental hosts)
• Access logs: history of every entry and exit
• Compatibility: Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, Matter (Ultra)

The Smart Lock Ultra is the only one with native Matter — the universal smart-home protocol backed by Apple, Google and Amazon — with no intermediate hub.

Nuki is regularly ranked best smart lock on the European market in specialist comparisons. The unanimously praised points: mechanical reliability, execution speed, a well-designed app and a complete range of accessories.

Dominant positive reviews: simple installation, flawless ecosystem integration (HomeKit, Alexa, Google Home), frictionless multi-user management. The Smart Lock Ultra is described as a "simply perfect" everyday experience in recent tests.

Watch-outs: the Smart Lock Go needs a separate Bridge (€49) for remote access, which can surprise at purchase. Calculate the total cost (Go + Bridge = €158) vs the 3.0 Pro at €249 — the difference is €91 for native Wi-Fi.

Before activating your Nuki promo code:

• Compatibility: Nuki works with most European locks (euro-profile cylinder). Check on nuki.io/compatibility that your lock model is compatible before ordering.
• Battery: the Smart Lock runs on AA batteries (4 to 8 by model), with 6 to 8 months of life in normal use. No wired power needed.
• Security: Nuki uses Bluetooth LE with AES-128 encryption, and cloud communications are TLS-encrypted. No unauthorised access has been documented to date.
• Promo code: reserved for direct purchases on nuki.io. Third-party resellers (Amazon, electronics retailers) don't guarantee codes will apply.

The Nuki lock doesn't work in a silo: it integrates natively with the main smart-home ecosystems on the market.

With Apple Home, you can lock your door via Siri, HomeKit automations or the Home app — with no complex setup. With Google Home and Amazon Alexa, voice commands work the same way. The Smart Lock Ultra adds Matter compatibility, the interoperable protocol that lets devices from different brands communicate natively.

You can, for example, create an automation: "when I get home, unlock the door AND turn on the lights" — pairing nicely with smart-home gear like Govee. For users who store access codes and sensitive data in the cloud, Microsoft OneDrive offers complementary storage.

A Nuki voucher is valid year-round — take advantage of it without waiting for the sales.
