Keypad Smart Door Knob Lock, Yamiry Keyless Entry Digital Lock with Handle

The Yamiry Keypad Smart Door Knob Lock provides keyless access for households looking to replace standard exterior or interior door hardware. Built from aluminum alloy, this handle set combines a backlit digital keypad with standard key access to eliminate the daily hassle of carrying keys.

Daily access is flexible and easy to manage. The system stores up to 20 separate 4-8 digit user codes for family members, along with a dedicated one-time code for short-term guests. Security features include an anti-prying entry mode to protect your combination and an IP54 weather resistance rating to handle outdoor moisture. It also features a low battery indicator to alert you before power runs out, while an auto-lock function can be set from 5 to 99 seconds or switched off completely.

Setup is straightforward, requiring only a screwdriver and under 15 minutes to complete. When looking at practical limitations, the listing does not mention the specific battery type needed for operation. Additionally, while the backup keys are standard and duplicable, you must arrange your own spares if you need more than what comes in the box.

Verdict: The Yamiry Keypad Door Knob is a practical, user-friendly lock for homeowners and property managers who want flexible code management. It offers reliable everyday convenience backed by solid aluminum construction and simple installation.

A great fit if you:

• Need multiple access codes for family members or service providers.
• Want an easy DIY installation that requires only a screwdriver.
• Prefer an automatic locking door that secures itself on a timer.
