On my third Nuki Smart Lock Pro in under twelve months. Each replacement due to mechanical failure. Today the device lost Bluetooth entirely — battery fully charged — leaving my family and dog locked outside in freezing conditions for four hours. The key cannot be used while the Nuki is installed, so there was no fallback. The only solution was an emergency locksmith costing €116.
Support confirmed they have zero remote access capability and can offer no diagnosis. Their advice: wait for a locksmith.
I'm not alone — other reviewers describe the same pattern of unreliable hardware, software updates making products worse, and customer service that is effectively non-existent. Trustpilot Connectivity dropping without warning is a widely reported issue across Nuki's developer community too. Nuki
A smart lock that can strand you outside your own home — with no fallback and no remote remedy — is not fit for purpose. Do not buy this product.
