Smart deadbolt for narrow out-swing doors

The Meterk IBLOG ZN-S12 smart deadbolt fits out-opening, narrow-stile storefront doors with a 2.75 in x 1.85 in x 6.29 in black lever-handle assembly. It runs on four AA batteries at 12 V and supports up to 100 fingerprints for families or small teams needing keyless access.

Two levers, app control and optional gateway

The pack includes two lever handles, a touchscreen keypad, fob cards and a physical key override. Built-in Bluetooth connects to the app within 810 meters for real-time lock status, passcode management and entry logs. Adding the separate G2 gateway enables remote control and voice-assistant integration.

No-drill install with auto hand detection

The lock auto-detects left- or right-swing doors and mounts on existing holes using only a screwdriver, preserving the door surface. IP54 weatherproofing suits exterior use. Buyers who need mortise-style fitment or hardwired power will find this cylindrical battery-operated design unsuitable.

Questions about this item

How often will the four AA batteries need replacing?

Battery life is rated at 9 months under normal use, so plan on swapping the four included AA cells roughly once a year.

What stops the lock from working during a long power outage?

The lock runs on four AA batteries, not mains power, so a household outage has no effect; only depleted cells will stop it.

How warm does the touchscreen get if the door is unlocked repeatedly all day?

The unit is IP54 rated for outdoor exposure and draws only 12 V from AA cells, so heat build-up during normal daily use is negligible.
