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 · Price last checked 20 Sep 2026, 12:29 BST · price-tracked
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.

- 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
- Each finish is a separate option, with its own ASIN, on the same Amazon listing; our link opens on Polished Brass (SD-L1000-PB), so check the finish selected before you buy
- 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
Who shouldn't buy this
Skip this if you'd rather keep your existing mechanical handle in place; this replaces it entirely, which is more work to fit than a clip-on retrofit unit.
