# Hand-Cranked Door Locks Ring Lets a Dial Wake Its Smart Deadbolt After a Dead Battery By Adam Harrie | Written with AI assistance | Published 2026-10-09 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/hand-cranked-door-locks References: [techcrunch](https://techcrunch.com/2026/10/07/rings-first-smart-lock-can-be-hand-cranked-when-its-battery-dies)  Ring is moving into smart locks with a deadbolt that can wake itself after a drained battery, helping homeowners avoid a lockout at the door. Its power dial is turned by hand to generate enough charge to open the lock, eliminating the need for a hidden spare key. The rechargeable pack is designed to last about a year, so a lightly used home does not require constant check-ins. Through the Ring app, owners can also [grant recurring entry](https://www.trendhunter.com/trends/philips-4200-series-wifi-smart-deadbolt) to dog walkers, reducing some of the key handoffs that usually come with part-time access. In daily use, the lock stays simple: a resident can tap a [fingerprint reader](https://www.trendhunter.com/trends/ultraloq-smart-home-locks) for quick entry and reach for the dial only if the battery has gone flat. It fits a [standard single-cylinder deadbolt](https://www.trendhunter.com/trends/schlage-sense-pro-smart-deadbolt) and is slated for U.S. sales in early 2027, pending FCC approval.
