The iuknob is a keyless door knob with a backlit keypad and a key cylinder on both sides, so one door can be controlled from inside and outside. Each keypad holds 50 codes, and a sync switch copies code changes from one side to the other. It runs on four AAA batteries with a Type-C emergency port, carries an IPX6 weather rating, and is built from zinc alloy. It suits gates, fences and doors that need entry control from both faces; most keypad knobs are single-sided, so this is a niche pick rather than a mainstream smart lock.

This keyless entry door knob has a keypad and a key cylinder on both sides of the door. The two cylinders use identical keys. That allows access control from inside and outside, for garden gates, fence doors, and exterior or interior doors.
Each keypad stores 50 access codes and is backlit. The lock can be set to lock automatically 2 seconds to 12 hours after the door closes, or to stay unlocked when there is a lot of traffic. Control can be bi-directional or uni-directional. With the sync switch on, a code change made on one side updates on the other side too.
The knob is made of zinc alloy with an electroplated coating and has 2 solid lock cylinders. It has an IPX6 rating and works in temperatures from -22°F to +176°F. It also has anti-peeping code protection, a low battery beep, and a Type-C USB port for emergency power. It runs on 4 AAA batteries, which can last over a year.
