Quick Comparison

Yale Linus Smart Lock

Tagline: A simple retrofit smart lock that keeps your existing key.

Yale Linus is a great entry point for smart locks in the UK. It attaches to your existing deadbolt, so you don't need to change your key or cylinder. Installation is straightforward, and it works with Yale's app for keyless entry and guest access. However, it lacks built-in Wi-Fi, so you'll need a separate bridge for remote access. It's best for those who want a simple upgrade without changing locks. Pricing is around £199, making it the most affordable option here.

• Pros: Easy DIY installation, works with existing key, affordable
• Cons: Needs extra bridge for remote control, no geofencing auto-unlock
• Best for: Budget-conscious users wanting a simple retrofit
• Pricing snapshot: £199 (approx., verify locally)

Tagline: Feature-packed with built-in Wi-Fi and Matter support.

It supports Matter, Apple Home, Google Home, and Alexa. Auto-unlock via geofencing is smooth. The motor is quiet and fast. Cons: It replaces your internal knob, which might not suit all UK doors. Installation is slightly more involved. Best for tech enthusiasts wanting advanced features. Price is around £249.

• Pros: Built-in Wi-Fi, Matter support, auto-unlock
• Cons: Doesn't use existing key, may require door modification
