Electronic Keypad Door Knob SoHo Mill YL 99 - DIY Keypad Lock

In this review the SoHoMiLL Electronic Keypad Door Knob YL 99 is evaluated for home offices, guest rooms and rental properties where controlled access and simple installation matter most. The bottom line: it is a practical, easy to fit keypad knob that replaces most existing door knobs without professional help and gives flexible code control and a mechanical backup key for reliability. The product is best for indoor or light-duty exterior use where a motorized deadbolt is not required and where users prefer no phone connectivity for privacy.

Key Features

• Easy setup: Designed for DIY installation so one person with a screwdriver can replace most standard knobs without calling a contractor.
• AutoLock: The knob relocks automatically 3 seconds after a valid code entry unless you physically turn the keypad knob, helping prevent accidental unlocking.
• Multiple codes: Stores a master code plus up to eight user codes and a P-Code, giving separate access for family, guests or workers.
• Backup mechanical key: Includes a failproof physical key and a battery low warning so you can still enter when batteries are depleted.
• No phone connection: Operates offline which reduces remote hacking risk and keeps control local to your master code.

Who It's For

The YL 99 suits homeowners and landlords who need a straightforward keypad for interior rooms, offices, guest houses or rental units and who value simple setup and local control. It is also a good choice for families wanting to restrict children's access to particular rooms without carrying keys.

It is not for buyers who need a motorized deadbolt or remote smartphone control; this model uses a spring latch that must be turned manually after entering a code, so those wanting automatic bolt actuation should look elsewhere.

Pros & Cons

Pros

• Easy DIY installation that fits most standard door knob holes and both left and right hinged doors.
• Strong build quality for indoor use and good value with multiple user codes and a master code.
• Security-minded features such as auto-lock, entry alerts, and offline operation to reduce hacking risk.

Cons

• Not a deadbolt: after entering a code you must turn the keypad knob within 3 seconds to open, which differs from motorized locks.
• Spring latch design means it will not offer the same level of exterior security as a heavy deadbolt for high-risk external doors.
