Choosing a smart lock sounds simple until you open the catalog and find six of them. The Connected Shop sells a full tier of fingerprint locks, and they are not interchangeable. Door type, the access methods you need, and whether you want the door to lock itself all change the right answer. This guide walks through each model so you can match the lock to your door instead of guessing.
Start With Your Door, Not the Lock
Before comparing features, figure out two things about your door: its type and its thickness. The Connected Shop locks are tagged for swing doors and sliding doors, and several support mortise and multipoint setups. A slim knob lock and a heavy deadbolt lock are engineered for different installations, so the door dictates the shortlist.
One feature is shared across the entire lineup and worth stating up front: every lock is subscription free, with no recurring payments ever. You are not comparing monthly plans, only hardware.

The Slim Family: Fast and Minimal
If you want the smallest visual footprint, start here. The Smart Door Lock Slim reads a fingerprint in roughly 0.5 seconds, unlocks remotely over Wi-Fi through the mobile app, and accepts passcodes or keycards. It stores up to 100 fingerprints and is tagged for both swing and sliding doors, including mortise and multipoint configurations. It comes in black, silver, and gold.
The Smart Door Lock Slim Knob is the variant for setups that need a knob-style fit rather than a lever, with the same instant fingerprint recognition and Wi-Fi unlocking. Pick the Slim if you want a clean lever look; pick the Slim Knob when the door hardware calls for a knob.
The Mini: Tight Fits and Adjustable Latch
The Smart Door Lock Mini is the choice when space or an awkward latch is the constraint. It uses an adjustable latch sized for 60 to 70mm, unlocks over Wi-Fi from the app, reads fingerprints, and accepts passcodes or keycards, supporting up to 100 fingerprints. It is tagged for swing doors with latch and mortise types. Reach for the Mini on interior doors or where a full-size lock simply will not sit right.
The Max: Built for Bigger Swing Doors
The Smart Door Lock Max steps up for larger swing doors and latch or mortise installations. It keeps the same core experience, instant fingerprint unlock, app-based Wi-Fi control, passcodes, and keycards, with a waterproof build. One practical difference to note: the Max is configured for up to 20 fingerprints rather than 100, which is plenty for a family but worth knowing if you plan to enroll a large team.

The Duo: Double-Sided Access
The Smart Door Lock Duo is the pick when you want secure entry from both sides of the door. It offers double-sided fingerprint and keypad access, Bluetooth app unlocking with an optional gateway for remote access, plus passcode and keycard entry. Its waterproof design is made for durable outdoor performance, so it suits exterior doors that take weather. Choose the Duo when a single-sided keypad is not enough and both sides of the door need real access control.
The Next Gen Smart Lock Pro: The Top Tier
For the most hands-off, highest-security option, the Next Gen Smart Lock Pro is the flagship. It adds two things the others do not combine: deadbolt auto-lock that engages the moment you close the door, and a 3D face and fingerprint recognition system, on top of remote Wi-Fi unlocking, passcodes, and keycards. It supports swing and sliding doors with mortise and multipoint setups. If you want to stop thinking about whether you locked the door, this is the model engineered to handle it for you.
Match the Access Methods to Your Household
Beyond door type, the second question is how people will actually open the door. Every Connected Shop lock supports more than one method, and the mix matters for who lives or works behind it.
- Fingerprint is the default on every model and the fastest for daily use, with the Slim, Slim Knob, and Mini reading prints in about half a second.
- Passcodes are ideal for guests, cleaners, or contractors you want to let in temporarily without enrolling a fingerprint.
- Keycards suit offices and rentals where a physical tap card is easier to hand out and collect.
- App and Wi-Fi unlocking lets you open the door remotely or check the unlock log from anywhere.
If you have children, frequent visitors, or staff, lean toward a model with the higher fingerprint capacity, the Slim family and the Mini each hold up to 100, while the Max is set for up to 20. For a couple or a single exterior door, 20 is rarely a limit you will hit.

A Quick Way to Decide
- Want the cleanest look and up to 100 fingerprints? Smart Door Lock Slim or Slim Knob.
- Working with a tight latch or interior door? Smart Door Lock Mini.
- Have a large swing door? Smart Door Lock Max.
- Need access from both sides outdoors? Smart Door Lock Duo.
- Want auto-lock and face recognition? Next Gen Smart Lock Pro.
Do Not Forget the Extras
Two accessories can save a headache. For double or French doors, the Dummy Handle matches the lock design in durable aluminum alloy so your passive panel looks intentional. And because these are battery-powered devices, keeping spare Batteries on hand means a low-battery alert never leaves you locked out. The brand also offers an optional Product Warranty Powered by SureBright if you want longer coverage.
Once you know your door type and how many people need access, the right model usually picks itself. When you are ready to look at colors and finishes, compare the full lock range side by side.
