| Documented use | Consider this interior retrofit when retaining the exterior deadbolt hardware and original keys matters. Confirm the existing deadbolt, mounting clearance and any required property permission before choosing a package. Use limits & sources | Replacing a compatible door's deadbolt with keypad entry and app-managed access through the Encode BE489 family. Plan for four AA alkaline batteries, 2.4 GHz Wi-Fi and a door prepared to the manufacturer's dimensions; check fit before choosing the finish or seller package. Use limits & sources | Replacing a suitable deadbolt with the keyed Assure Lock 2 touchscreen and Wi-Fi configuration, with app-managed entry codes. DoorSense can report open/closed state after installation and calibration. Confirm the exact Wi-Fi module, four-AA battery setup and seller kit for YRD420-WF1-619. Use limits & sources |
| First setup check | Mounts on the inside of a compatible existing single-cylinder deadbolt; check August's deadbolt compatibility list first. Full setup checklist & sources | Encode BE489 replaces the deadbolt; it does not retain the existing exterior lock like a retrofit accessory. Standard fit is a 1-3/8 to 1-3/4 inch thick door with a 2-3/8 or 2-3/4 inch backset (door edge to hole center). Measure before buying. Full setup checklist & sources | This keyed YRD420 replaces the deadbolt, rather than retaining the existing exterior lock. Yale specifies 1-3/8 to 2-1/4 inch door thickness, 2-3/8 or 2-3/4 inch backset, and a 2-1/8 or 1-1/2 inch face bore. Verify the door and required adapter before buying.

Compatibility evidence
Not assigned / insufficient verified evidence
Final recommendation
Conditional by requirements. Best overall, best value, renters, and advanced-user labels are not assigned because verified evidence is insufficient.
Evidence limits
- No controlled outcome, installation, total ownership cost, renter-fit, or advanced-user study is recorded for these products.
- Only current authorized price and Amazon owner-feedback observations provide context; they are not an editorial score or a best-value verdict.
- A catalog yes/no is not verification of a supported function. A missing or negative catalog entry does not establish incompatibility; confirm model, firmware, bridge/controller roles and required services.
- Current authorized price differences are unavailable for one or more products. Check price on Amazon; no budget or value comparison is verified.
- August Wi-Fi Smart Lock is missing verified current authorized price, current authorized Amazon owner rating/count.
- Schlage Encode Smart WiFi Deadbolt is missing verified current authorized price, current authorized Amazon owner rating/count.
- Yale Assure Lock 2 Wi-Fi is missing verified current authorized price, current authorized Amazon owner rating/count.
Quick decision framework
- Identify the task, exact model and installation requirements; treat unverified compatibility fields as questions to resolve, not filters that certify support.
- Check current prices and customer feedback on Amazon when verified data is unavailable here.
- Open the product profile and current Amazon listing before purchasing.
Decision guidance: Check mechanical fit, original-key or keypad needs, permissions, and the actual model and accessories. Catalog platform flags do not certify commands, battery endurance, security or reliability.
