Frequently asked questions

Most likely. The Bold Classic fits most doors with a Euro profile cylinder, which is the most common type in Europe. It is available in eight different sizes so you can match it precisely to your door thickness. Use our sizing guide to measure both the outside and inside length of your current cylinder, and you will know exactly which lock size you need. This will ensure a perfect and secure fit.

Non fa cilecca... per ora!

Funziona perfettamente ed è molto pratico da usare. Ho provato a chiudere la app e riavviarla, a disattivare e riattivare il bluetooth e persino a spegnere e riavviare lo smartphone XIAOMI, ma il Bold Smart Lock non ha mai fatto cilecca. Ora lo aspetto alla prova del tempo: voglio proprio vedere quanto dura la batteria!

In a word, fantastic, and that should be said sometimes.

As a computer illiterate I had to change my email address because it no longer existed and I forgot my password, but that was handled perfectly and everything is working great again. Bas helped me tremendously.

A must-have for every door. Not just for tech enthusiasts.

As expected. This is my second lock, and everyone in the family already has one. Easy peasy to install and works perfectly. And the battery lasts forever 😉
