Description

With the Bold Elite Smart Lock SX45 Silver, you can leave your house carefree. When you install this lock, you replace the whole door cylinder. That way, the smart lock fits in almost every door. The SX45 is suitable for a door cylinder with an outdoor dimension up to 65mm and an indoor dimension up to 45mm. You can control this lock via the Bold app on your smartphone. You can check if you closed the door and receive a notification if you forgot.

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.
