Best Smart Lock for a Door with a Mortice and Night Latch: 5 Picks That Fit Real UK-Style Doors

A door with a mortice lock and a night latch is one of the trickiest hosts for a smart lock: the mortice body sits inside the door edge, the night latch is surface-mounted on the face, and a standard deadbolt swap often will not work without cutting timber. This guide covers five options that solve that problem in different ways — a surface-mount rim lock that replaces the night latch outright, a full mortise handle set, a deadbolt-plus-handle bundle, a certified brand-name deadbolt, and a video-doorbell hybrid. It suits renters who cannot cut a door, owners upgrading a traditional front door, and anyone who wants camera coverage at the entry. The overview table below ranks all five at a glance.

1. Lokko Digital Electronic Night Latch Rim Lock

Type: Surface-mount rim lock
Intended use: Wooden front doors, yard and garden gates
Installation: No mortise required
Environment: Outdoor-rated
Access: Digital electronic entry

Lokko Digital Electronic Night Latch Rim Lock

The Lokko is the only pick here built specifically around the night-latch format. It mounts on the face of the door rather than inside the edge, so the existing mortice body can stay exactly where it is — no chiselling, no new cutouts, no locksmith. That makes it the natural first choice for anyone whose main obstacle is the mortice itself.

It is also the pick for gates and outbuildings, since a surface-mount rim lock does not depend on the door’s internal structure the way a mortise does. Buyers who want to keep their original door and hardware intact, including renters, get a working smart lock with the least disruption.

Trade-off: A surface-mount rim lock is bulkier on the face of the door than a recessed deadbolt, and it will not give the flush, built-in look some owners want on a period front door.

2. 8-in-1 Fingerprint Front Door Lock with Handle

Type: Mortise lock with integrated handle
Access: Fingerprint, 3D face recognition, palm vein, keyless entry
Camera: Built-in video doorbell with two-way talk
App: Tuya
Weather rating: IP67
Alarm: Loitering detection

8-in-1 Fingerprint Front Door Lock with Handle

This is the most feature-dense option in the roundup and the one that replaces the most hardware in a single purchase. The mortise body, the handle, the camera and the keypad all arrive as one set, which suits a buyer who is already replacing the whole door setup rather than adding to it.

The biometric spread is unusually wide — fingerprint, 3D face and palm vein — so households with different preferences or unreliable fingerprints have more than one way in. The IP67 rating and loitering alarm make it plausible for an exposed front door, and the two-way talk covers the parcel-delivery conversation without a separate doorbell.

Trade-off: A full mortise handle set is the most invasive install in this list, so it is not for renters or anyone unwilling to modify the door edge — and a feature set this broad means more setup before the first entry works smoothly.

3. Philips Wi-Fi Smart Deadbolt Lock with 2 Handles

Type: Smart deadbolt with two handles
Access: Code, fingerprint, app, voice
Connectivity: Built-in Wi-Fi
Extras: Auto lock, backlit touchscreen, remote access
Voice: Alexa and Google

Philips Wi-Fi Smart Deadbolt Lock with 2 Handles

The Philips pick is the practical middle path: a deadbolt rather than a rim lock, but bundled with two handles so the door hardware matches and the buyer is not hunting for compatible trim. Built-in Wi-Fi means no separate hub, which keeps the setup simple for a household that just wants remote access and voice unlock.

Auto lock is the feature that matters most on a door with a night latch, because it removes the "did I lock it?" check from the routine. The backlit touchscreen helps on a dark doorstep, and the fingerprint reader covers the case where a code is forgotten.

Trade-off: A deadbolt still needs a bore and cutout in the door, so a door that currently relies only on a mortice and night latch will need modification before this fits.

4. Schlage Encode Smart WiFi Deadbolt with Greenwich Trim

Type: Smart Wi-Fi deadbolt with trim
Access: Touchscreen keypad, app, keyless entry
Connectivity: Built-in Wi-Fi
Ecosystems: Alexa, Google Home, Ring, Airbnb
Finish: Matte black

Schlage Encode Smart WiFi Deadbolt with Greenwich Trim

This is the pick for buyers who care more about the lock brand than about the smart features. Schlage is a long-established lock maker, and the Encode line is its mainstream Wi-Fi deadbolt — a reassuring choice for anyone uneasy about an unfamiliar name guarding the front door.

The ecosystem list is the widest here, with Alexa, Google Home, Ring and Airbnb all supported, which matters for a short-let or a smart-home household already committed to one platform. The matte black Greenwich trim is a deliberate style choice rather than a generic finish.

Trade-off: This is a deadbolt only — no handle, no camera, no biometrics — so a door with a mortice and night latch still needs the mortice addressed separately, and the brand premium buys reliability rather than features.

5. myQ Secure View 3-in-1 Smart Lock

Type: Smart lock with integrated video doorbell
Camera: 2K HDR with color night vision
Access: Face, fingerprint, PIN, app
Audio: Two-way
Brand ecosystem: myQ

myQ Secure View 3-in-1 Smart Lock

The myQ Secure View consolidates the lock and the doorbell into one unit, which is the appeal for a front door that currently has neither. The 2K HDR camera with color night vision is a step above the usual doorbell resolution, and face plus fingerprint access means the household rarely needs to reach for a phone.

It is the strongest pick for anyone who wants to see who is at the door before unlocking, and for a home where a separate doorbell would be awkward to wire or mount. The two-way audio and app control round out the entry experience.

Trade-off: The camera and display hardware push this into premium territory, and a combined lock-and-camera unit is a single point of failure — if the camera module develops a fault, the whole entry device is affected.

Before You Buy

• Compatibility: Confirm whether the door’s mortice body sits in the edge or whether the night latch is surface-mounted — that single fact decides whether a rim lock, a mortise set or a deadbolt is the right purchase.
• Door thickness and material: Solid timber, composite and hollow-core doors take smart locks differently; a surface-mount rim lock is the most forgiving across all three.
• Installation skill: A rim lock is a screwdriver job; a mortise handle set or a new deadbolt needs a drill, a chisel and patience, or a locksmith.
• Power source: Battery-powered locks need a replacement routine; check how the app reports low battery before relying on keyless entry alone.
• Connectivity: Built-in Wi-Fi avoids a hub but drains batteries faster; a hub-based system can be more efficient in a large home.
• Ecosystem: Match the lock to the voice assistant and smart-home platform already in use rather than adding a second app.
• Security and insurance: Check that the chosen lock meets the requirements of the home insurance policy, particularly on an external final-exit door.

Frequently Asked Questions

1. Can a smart lock replace a mortice and night latch?
   Yes, but not with one product type. A surface-mount rim lock replaces the night latch while leaving the mortice in place; a mortise handle set replaces both; a deadbolt replaces neither without additional work.

2. Which pick is easiest to install on a door with a mortice and night latch?
   The Lokko rim lock, because it mounts on the door face and requires no mortise cutting or new bore holes.

3. Do these locks work on wooden front doors?
   All five are intended for residential front doors, and the Lokko is explicitly aimed at wooden doors and garden gates. Composite and uPVC doors need a check against the lock’s fitting instructions.

4. Is a smart lock with a camera worth the extra cost?
   For a door with no existing doorbell, a combined unit like the myQ saves a separate purchase and install. For a home that already has a video doorbell, a lock-only pick is better value.

5. Will a smart deadbolt fit where a night latch is now?
   Not directly. A deadbolt needs a bore hole and a edge cutout, so the door must be modified — which is why the rim lock and mortise options exist.

6. Do these locks work with Alexa and Google Home?
   The Philips and Schlage picks both list Alexa and Google support. The others rely on their own apps, so check the ecosystem before buying.

Bottom Line

For most doors with a mortice and night latch, the Lokko Digital Electronic Night Latch Rim Lock is the pick that solves the actual problem with the least disruption — it replaces the night latch, leaves the mortice alone, and needs no cutting. Buyers replacing the whole door setup should look at the 8-in-1 mortise set, and anyone who wants camera coverage at the entry should go straight to the myQ Secure View.
