Yale Linus Smart Lock L2 review
Homeowners who want to add app and PIN access to an existing UK cylinder lock without swapping out their current deadlock.
By Tom Calder · Price last checked 20 September 2026 · price indicative
A genuinely useful way to add smart control while keeping your existing mechanical lock and key in place, but it doesn't add insurance-rated security itself — Yale's own recommended companion cylinder is TS007 3-star rated, a different standard from the BS3621 most insurers ask for, so check the small print rather than assume.

- Retrofits onto your existing cylinder with no locksmith drilling required
- Mechanical key keeps working as a backup at all times
- Sold via an Amazon Marketplace seller (Rarewaves) rather than dispatched by Amazon directly, so it's worth checking return terms
- Battery life is 'up to' 6 months and varies with usage and signal, not a fixed figure
- Doesn't itself carry a BS3621 rating — the companion cylinder Yale suggests is a different (TS007 3-star) standard
Who shouldn't buy this
Skip this if you need a lock that is itself BS3621-insurance-rated; check your existing deadlock's own certification instead, since the Linus L2 doesn't add one.
