Best Mortise Smart Locks (2026)
The best mortise-style smart locks for 2026.
At a Glance
Mortise locks fit into a pocket carved directly into the door edge rather than a simple crossbore, common on older or heavier doors and sliding glass entries. Here's how the top current mortise-style smart options compare.
5 Criteria to Look For Before Buying a Mortise Smart Locks (2026)
Key buying criteria so you get the right fit the first time.
Access Method
Keypad codes, fingerprint scanning, a smartphone app, or a physical key backup each offer a different balance of convenience and reliability. Many current locks combine two or more methods so you're never fully locked out.
Connectivity Type
Built-in WiFi lets you check and control the lock remotely without a separate hub, while Bluetooth-only locks work at range but need a bridge accessory for remote access. Matter and Z-Wave options integrate with a broader smart home hub.
Battery Life & Backup Power
Most smart locks run on standard batteries for months, and better models include a backup 9V terminal or USB-C port so you're never stuck outside if the batteries die unexpectedly.
Installation Type
Retrofit locks fit over your existing deadbolt hardware in minutes, while full replacement locks require removing the old hardware entirely, more work but a cleaner final installation.
Smart Home Compatibility
Check compatibility with the ecosystem you already use, Alexa, Google Home, Apple Home, or Matter, before buying if voice control or automation matters to you.

Frequently Asked Questions
Do smart locks work during a power outage?
Yes. Smart locks run on batteries, not household power, so they keep working during a power outage. The concern is dead batteries rather than a power outage, which is why most models include a backup access method like a physical key or a 9V terminal for emergency power.
Can a smart lock be installed on any door?
Most smart locks are designed to fit standard US door prep (a 2-1/8 inch crossbore), which covers the vast majority of American front doors. Retrofit models specifically fit over an existing deadbolt, while full replacement locks require standard deadbolt door prep. Check the listing's compatibility section if your door has unusual hardware.
Is a smart lock as secure as a traditional deadbolt?
Most current smart locks use the same ANSI/BHMA-graded deadbolt hardware as traditional locks, with the electronic components as an addition rather than a replacement for physical security. Look for an explicit security grade rating in the listing if this is a priority.
Do I need a hub to use a mortise smart lock?
It depends on the connectivity type. Locks with built-in WiFi work without any separate hub. Bluetooth-only locks typically need a bridge accessory (sold separately or bundled) for remote access away from home; without one, they still work fine at close range via the app.
How long do smart lock batteries last?
Most current models claim several months to about a year of battery life under normal use, and better models send a low-battery notification through the app well before they die, along with a backup power option so you're not locked out.
