Overview
Amazon Basics pairs an entry knob with a deadbolt in this set, so one key opens both. The finish is matte black over brass, the handle is zinc, and the set is described as easy to install on an exterior door.
The reason to buy is the deadbolt and knob on a single key, which adds a second lock point to an entry door. The limitation is that fit details are missing, so backset and door thickness have to be checked separately.
Who it's for
Home owners upgrading a front or side entry to a matching black set will like the single key. Buyers with unusual door thickness or smart-lock plans should confirm fit first.
Pros and cons
- Deadbolt and knob on one key
- Matte black finish
- Brass and zinc construction
- Backset range not listed
- Warranty not described
- Interior finish not described
Performance notes
Having both locks keyed alike removes the second key on a ring, and the deadbolt adds a bolt that a knob latch alone does not. Brass and zinc resist corrosion in damp coastal air. A correct door bore and backset decide whether the set installs without modification.
