Compatible with all standard Euro cylinders, this Bluetooth or WiFi enabled smart lock is designed for supreme safety and security, 100% keyless and controllable remotely with the free Bold app, wherever you are. The Bold Smart Lock has been rated with a maximum SKG certification (SKG***), making it the safest smart lock for your home, office or business.

The SX-33 is suitable for traditional euro cylinders with an indoor size of 20-35mm and an outdoor measurement of 30-45mm. Easily install your Bold smart lock in just under 5 minutes. If you'd like any guidance on how to measure your lock to find the right size for you, check out our FAQ!

This lock works to provides additional security to your home, office or business, having been certified with the highest possible SKG*** security certification for heavy duty burglary resistance. Bold's servers are also encrypted with the latest software used for online banking, ensuring they're protected from any form of hacking or communication manipulation.

Manage access permissions with peerless ease and safety with the free Bold app! Your employees, cleaning staff and delivery heroes can open the doors using their phone as their key, and you can fully customise these permissions wherever you are.

There's also no motor with Bold, so batteries can last for years, not days. The external door knob simply rotates freely until the Bold automation is activated, and engages it with the lock cylinder to function as normal.
