Yale Conexis L1 Smart Door Lock review
Households wanting to replace their entire door handle with a keyless smart handle rather than just adding an actuator.
By Tom Calder · Updated 24 July 2026 · Price checked against our tracker
A full handle replacement that's genuinely BSI-tested to its own standard, TS621:2018, with a tamper alarm and PIN lockout as useful extras. But TS621 is a smart-lock-specific standard, not the BS3621 mortice deadlock standard insurers usually name, so it isn't an automatic insurance tick.
Confirmed live on Amazon UK as of 24 Jul 2026 for the standalone Polished Brass handle; other finishes and bundles have been seen between £162 and £199.

- Replaces the whole nightlatch/handle assembly rather than just adding an actuator
- BSI-tested to TS621:2018 with a tamper alarm and lockout after repeated wrong PIN entries
- Works via Bluetooth from your phone without needing a separate hub
- The exact bundle we sourced (Satin Chrome with Sync Alarm Module) is currently out of stock, so price and finish depend on what's available
- TS621:2018 is a different BSI standard from BS3621 and isn't confirmed to satisfy insurer wording that specifically names BS3621
- Runs on 4 x AA batteries rather than a rechargeable pack
