Classic on the Outside, Smart on the Inside

The external door knob's subtle twist-turn design encased within Finfort lockguards maintains a classic look on the outside. The Bold smart cylinder houses its smart functionality within the internal door knob.

We believe security should also be stylish so Finfort smart locks are available in six elegant finishes, colour matched to Heritage Brass Door Furniture which is widely available.

Digitally Secured with Two-Factor Authentication

All messages between the Bold smart cylinder and the Bold server are end-to-end encrypted to the same standard as online banking.

Each lock has a unique, unclonable code — ensuring security that can’t be bypassed or duplicated.

High Security

With a 21mm automatic mechanical deadbolt, a Finfort smart lock surpasses the security standards of all smart locks, which typically rely on latches or require battery operated deadbolt activation.

Extra Long Battery Life

The Bold smart cylinder boasts a very long battery life, lasting over 2 years or 20,000 activations, significantly outlasting motorised smart locks. You will also be notified if your battery is low.

Smart auto-deadbolt nightlatch in polished brass finish — features a 21mm mechanical deadbolt for enhanced security and a long-lasting battery life of over 2 years.

Insurance Compliant

To meet home insurance standards, wooden doors require a British Standard BS3621 certified deadlock, operated with a key on both sides. Finfort pairs its Smart Auto-Deadbolt Nightlatch with an insurance-rated deadlock, to create an insurance compliant Smart Dual Door Lock Set.

Enjoy day-to-day keyless access and choose when to use the manual deadlock, say for longer absences.
