The lock replaces the cylinder you now have, so it fits on almost every door.

You can give others access to the lock, so you know exactly who entered and when.
When replacing the cylinder, always check the correct dimensions, so the door lock fits in your door.
With a Bold Connect bridge, you can control the door lock from every location via internet, this isn't included.

Description

With the Bold Elite Smart Lock SX35 Silver, you never forgot to lock your door again. This smart door lock fits on almost every door, because you replace the whole cylinder. The SX35 is suitable for a door cylinder with an outdoor size up to 65mm and an indoor size up to 35mm. Via your smartphone, you can control the lock. You receive a notification when the door isn't locked and you're not at home. You can also give others access via the Bold app. For example, you can set days and times when friends and family can open the lock. Does someone try to enter without access? The app sends a notification and you can take action right away. Note: you need a Bold Connect bridge for some functions, which isn't included.

Top product!

Very easy to install (even with my two left hands)
Recently also with Matter
Can be linked to Homey and Apple Home

I was looking for a reliable and smart lock. After extensive research, I ultimately chose the Bold Elite. It's easy to install and integrate into my smart home (matter). It works with Apple Home and Homey, allowing me to trigger all sorts of smart actions when the door opens or closes.
