Best Lock Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Puroma is the best-performing lock brand in July 2026, moving 29,000 units across 3 ASINs for 27.9% of Top 10 volume. Skyla Homes follows with 20,000 units (19.2%), ahead of Forge on 17,000 units (16.3%).
With 7 brands splitting the Top 10 and 63.5% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $9.85 to $17.73, which frames the price band a competing listing has to justify.

Trending Lock Products — Growth Leaders & New Top 10 Entrants
Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, 3 ASINs forced its way in: B00005JSBK booked 10K units at $0.00, with ▲ 42.9% MoM change.
The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
