Overview
Amazon Basics matte black entry set pairs a keyed knob with a keyed-alike deadbolt, so one key works both locks on a coastal-style exterior door. Brass body with a steel internal structure and a zinc alloy latch bolt, backed by a 1-year limited warranty.
- Four keyed-alike brass keys included
- Adjustable latch backset 2-3/8 to 2-3/4 inches
- Rounded steel faceplate and strike plate
- 1-year Amazon Basics limited warranty
Who it's for
Fits anyone replacing a worn exterior door knob and deadbolt who wants a single key for both and is comfortable installing hardware with a screwdriver. Fits standard doors 1-3/8 to 1-3/4 inches thick.
What buyers say
From Amazon customer reviews.
Reviewers who installed it themselves generally called it an easy swap that looks sturdier than its price suggests, and several confirmed the knob and deadbolt take the same key. The recurring complaints are the included screws, which more than one buyer called undersized or hard to seat, and a deadbolt some found slower to align than the knob. One buyer reported a unit that jammed and would not lock properly, and a couple mentioned the matte black finish scratching.
