iulock Smart Keypad Door Lock — Matte Black electronic knob, 50 user codes, IP65 waterproof, Type-C backup

The iulock Keypad & Key Smart Door Lock is a heavy-duty electronic doorknob that supports up to 50 programmable codes, offers IP65 weather resistance, and includes USB Type-C backup for reliable keyless access.

Designed for exterior and interior doors, this matte-black smart knob combines a tactile, detachable silicone grip with a backlit numeric keypad so families, hosts and small businesses can move past keys. The iulock unit pairs mechanical backup keys with a solid metal construction and multiple convenience modes — passage, silent and auto-lock — plus long battery life and wide temperature tolerance for year-round use.

How many unique access codes can I create and how are they managed?

You can store up to 50 user PINs, each between 1 and 15 digits, so homeowners, guests or staff each get their own code. Codes are added or removed through the keypad and include simple steps for temporary codes when you need short-term access.

• 50 customizable PINs, 1–15 digits each
• Add, delete or change codes directly at the keypad
• Supports temporary or shared codes for short-term visitors

What security and backup options keep me from getting locked out?

The lock blends electronic convenience with traditional mechanical safety: a solid lock cylinder and two physical keys are included for manual entry. For power issues there’s a Type-C USB emergency port and a low-battery alert, while four AAA batteries typically last up to 18 months under normal use.

• Solid metal construction with two mechanical keys included
• Type-C USB backup power input for temporary operation
• Low-battery alarm plus estimated 18-month battery life on 4 AAA cells
