If a product passes the tests of SKG it can get a quality mark of 1, 2 or 3 stars. The higher the number of stars, the higher the burglary resistance. The stars indicate how long burglars are delayed.

Bold Smar Lock App Mobile

The Bold Smart Lock App

Decide who gets access, when. You are always 100% in control.

Wouldn't it be nice to have 100% control of your front door? The Bold Smart Cylinder allows you to decide who gets access, when and where. Your partner? Always access. The cleaner? Tuesday between 9:00 and 10:00. Anyone else? No access. Why use old-fashioned keys when you have 100% control over your home remotely with your smartphone and the smart Bold Smart Cylinder?

Keys are a thing of the past

Isn't it obsolete that we still use keys to open our front door? When you're away from home, you never really know what's going on. And if you lose your keys, the lock has to be replaced and new keys have to be created. It's a time-consuming job with unnecessarily high costs. With the Bold Smart Cylinder, a new era is dawning. With it, you decide who gets access, whenever you want.

Turn on notifications

With the Bold app you have total control over your home or office. Turn on your notifications and stay up-to-date, up to the second on what's happening to your front door. If someone comes in, you will be notified immediately. Thanks to the unique tracker, you also know immediately who has entered. It's such a nice feeling to know that the children are safely home from school. With the Bold Smart Lock,  way you always know exactly who has been in your home, now and in the past.

100% secure

Is there somebody out front without access? Then it's up to you to decide who gets access, remotely. That way you always keep an eye on visitors. That's such a nice idea. It's also a safe feeling. Speaking of which, how safe is the Bold Smart Cylinder? Extremely safe, as it's been awarded the SKG *** classification, the most burglar-resistant rating there is.

Decide who gets access

Is a friend coming to your house to pick something up, but you're not around? Then give them limited access to your home, for example for an hour. With the Bold Smart Cylinder you don't have to be at home anymore. You just give your friends access via the Bold app. Does the cleaner come by every Tuesday between 9:00 and 10:00? That's also easy to set up. That's how simple the Bold Smart Cylinder works.

The Bold Smart Lock PIN App

Emergency backup PIN code access for when you're stuck in a pickle

The Bold Smart Cylinder is completely keyless, even if you've forgotten your smartphone once or if its battery runs out. In that case, you can always open the door with a backup PIN code. You generate this code yourself in the Bold-app and enter it by turning the outside knob.
