M&C Cylinder

Bold smart lock

With the Bold Smart Lock, you can now open your doors without keys. All you need when you leave the house is your smartphone! And even that's unnecessary with the PIN code provided by the Bold smart lock.

You can quickly and easily replace your existing door lock with the Bold Smart Lock. Simply remove your existing cylinder, install the Bold Smart Lock, mount the knob, and your smart cylinder is ready to use.

Open with Bold app

Using the Bold app on your smartphone, you can then unlock the lock. And to make things even easier, Bold has developed "auto-activation." You don't even have to take your phone out of your pocket, because the lock recognizes you when you're at the door. When you activate this feature in the app, Bold uses your smartphone's location to calculate your distance from the lock. Once you're within Bluetooth range of the lock, it will unlock. After that, all you have to do is turn the lock and step inside.

Phone empty or forgotten?

No problem. You can always open the door with a PIN code by setting one in the app beforehand. Enter the PIN code by turning the knob alternately to the left or right for each number.

The app lets you manage who you grant and deny access to. You can also grant temporary access to your home, business, or Airbnb. These access permissions can be set up once, for a fixed period, or via a recurring schedule. The app will notify you if someone opens the door when you're not home, and Bold Events lets you easily track who operated the Bold Smart Lock and at what time.

Bold Connect

Want to activate and deactivate the lock remotely? Connect your smart cylinder to the Bold Connect. Convenient when you're on your way home and your friends are already at the door, or when you want to give guests remote access to their vacation rental or Airbnb.

Bold Clicker

With the Bold Clicker, you can open doors with a single push of a button, even without a smartphone. This small remote control is ideal for seniors and children without a phone.

The Bold Smart Lock fits any lock with a Europrofile cylinder recess. It's available in various lengths, and the outer casing can be easily extended with the included extension adapters. It's battery-powered, with a lifespan of approximately two years and/or 20000 activations.
