Independent testing
How much independent testing exists for each smart lock
Of the 8 smart locks we track, 5 have been physically measured by at least one independent lab and 1 by three or more. Below is every one, ordered by how much independent hands-on evidence stands behind it — densest first.
A coverage record, not a ranking of which is best.
| Product | Independent labs | Metrics measured | Outlets on record |
|---|---|---|---|
| Yale Assure Lock 2 | 4 | 5 | 4 |
| Level Bolt | 2 | 1 | 3 |
| Ultraloq U-Bolt Pro WiFi | 2 | 1 | 2 |
| Level Lock | 1 | 2 | 2 |
| Schlage Encode Plus | 1 | 1 | 4 |
| August Wi-Fi Smart Lock (4th Gen) | 0 | 0 | 2 |
| Level Lock Pro | 0 | 0 | 1 |
| Schlage Encode | 0 | 0 | 4 |
Each figure is a count of what independent testers actually did — how we count. A low count means little independent evidence has been gathered yet, never that a product is worse. See also the Smart Locks buying guide and the reviewers we cite.
