Haidms Keyed Entry Black Door Knob Interior & Exterior Locking Set

In this review of the Haidms Keyed Entry Black Door Knob set, the bottom line is simple: this five-pack is for homeowners or contractors who need economical, consistent keyed entry knobs for multiple interior or exterior doors where basic security and a uniform matte black look matter. The standout reason to consider these is their emphasis on durable materials - stainless steel bodies, solid brass cylinders and heavy duty latches - paired with a familiar keyed-turn operation that fits most standard doors, making installation straightforward for routine home projects.

Key Features

• Durable construction: Stainless steel bodies combined with solid brass cylinders and nickel plated bolts aim to resist wear and extend service life.
• Adjustable latch: The latch is adjustable from 60mm to 70mm (2-3/8 to 2-3/4 in) so it can accommodate common door jamb preparations.
• Standard door fit: Designed for doors 1-3/8 in to 1-3/4 in thick, it fits most interior and exterior residential doors without extra modification.
• Keyed locking: Each knob locks from the inside with a turn button and unlocks from the outside with a key, providing basic keyed entry security.
• Complete installation kit: The set includes all necessary accessories and clear instructions to help an average DIYer install multiple knobs quickly.
• Versatile style: The matte black finish suits a range of decors from modern to classic for consistent door hardware throughout a property.

Who It's For

The Haidms keyed entry knobs work well for homeowners renovating several rooms, landlords refitting rental unit doors, or contractors who need an affordable bulk option that looks uniform and installs fast. The five-pack is particularly convenient where multiple doors require matching hardware, such as bedrooms, laundry rooms and exterior entrances that use keyed locking.

Shoppers who need high-security commercial-grade locks or advanced key control should look elsewhere, as these knobs are intended for residential use and deliver solid basic protection rather than restricted-key systems or heavy-duty commercial certification.
