Start with your door
Tell us the door. We'll tell you the lock.
Most people don't need a spec sheet. They need the right answer for the door they already have. Here it is, plainly.
New front door
SS Slim or KF Smart Lock
The SS is our flagship: letterbox-safe, waterproof both sides, Wi-Fi built in. The KF is the compact essential pick for keyless entry on a budget.
See the SS Slim →I already have a euro cylinder
MF Euro Cylinder
The motorised MF swaps in in about 5 minutes with no drilling. NF, the weatherproof version, is coming soon.
See the MF →Letterbox near the lock
SS Slim
Letterbox-safe by design, so it can't be fished open through the mail slot, a classic weakness of many front doors.
See the SS Slim →Internal door
Leverline
The simplest keyless handle for internal doors: a straight handle replacement, opened with a touch. The SS also suits internal installs.
See the Leverline →Exposed to weather
SS Slim
Waterproof access panels on both sides, built for doors that face real weather. The NF euro cylinder (also waterproof) is coming soon.

Straight answers
The choosing questions, answered.
Which lock should I get for a brand-new front door?
The SS Slim is our flagship: letterbox-safe, waterproof both sides and our most advanced security, with Wi-Fi built in. The KF Smart Lock is the compact essential pick if you're watching the budget. Both give keyless entry on new or upgraded doors.
Which Simpled lock is easiest to install?
The MF Euro Cylinder. If your door already has a euro profile cylinder it's a DIY swap in about 5 minutes with no drilling, around 30 minutes all-in, rated Easy. The KF Smart Lock and Leverline are also easy ~30-minute fits. The SS Slim is a full fit at around 45 minutes.
Do Simpled locks work with Alexa and Google Home?
Yes. Every model supports remote unlock, Alexa and Google Home. On the KF, MF and Leverline this requires an external Wi-Fi gateway, sold separately. The SS Slim is the only Simpled lock with Wi-Fi built in, so it needs no separate hub.
Do all Simpled locks have fingerprint entry and a key backup?
Yes. Every Simpled lock in the US range includes fingerprint entry, a passcode and fob reader, a mechanical key backup and smartphone app access, with access sharing, scheduling and a full access log in the app, plus a 2-year Simpled warranty.
