Amazon's First Smart Lock Bets on Fingerprint, Codes and Hand Power

Amazon has announced its first smart lock, the Ring Smart Lock. It will cost $249 and come in black, silver and brass, with US availability expected in early 2027 pending FCC approval The Verge.
Access is checked on the lock itself. It offers unlocking by fingerprint reader and by backlit touchscreen keypad The Verge. No separate code needs to be entered in an app for normal entry.
Power comes from a replaceable Quick Release Ultra Battery Pack. The lock connects over Amazon Sidewalk, a low-bandwidth shared network that relays through nearby compatible devices, rather than home Wi-Fi The Verge.
The mechanical detail is in the interior thumb-turn dial. Ring has built an emergency charger into the dial to generate power when the rechargeable battery dies The Verge. Amazon claims turning the dial a few times generates enough power to unlock the door and fully recharge the battery The Verge.
The broader context here is failure handling, which is where smart locks win or lose trust. A dead battery is not an edge case. It is the normal end state of any battery-powered door hardware. Most designs answer it with a 9V jump contact, a USB-C emergency port, or a physical key override. Each requires the resident to have something else at the door at the right moment. A hand-cranked charge path built into hardware already in the hand is a different answer, because it removes that second dependency.
Looking at what this means for operation, the questions an installer will ask are practical. How much turning force and how many rotations are actually needed after a full depletion, how the system signals low charge before that point, and how the lock behaves if power fails mid-throw, while the bolt is partway out. For rental properties and multi-user households, the service model also matters. A replaceable pack allows a charged spare to be rotated in seconds, while the built-in harvesting dial covers the case where no spare was staged. Dead batteries lock people out. Redundancy is the product.
Looking at what this means for connectivity, Sidewalk instead of Wi-Fi is a power-budget decision with system tradeoffs. A low-bandwidth, shared-infrastructure link can reduce the cost of keeping a lock reachable for remote lock, unlock and status when no one is home, without the constant background signaling Wi-Fi needs to stay connected. The tradeoff is dependence on that network's coverage and bridging in a given home, plus the operational question of setup, fingerprint and code enrollment, and firmware updates over a constrained link. For a tech-literate buyer, the relevant test will be response delay under load, behavior during an ISP outage, and how cleanly fingerprint templates and PINs can be managed without exposing them to the network path.
In my view, the combination worth watching is biometrics plus keypad plus manual energy backup. Fingerprint offers speed for daily use. Backlit keypad offers delegable codes for cleaners, contractors and short stays. Manual charging offers a last-resort path that does not require a cable or a key. None of those inputs is novel on its own. Together they describe a lock intended to stay usable across depleted batteries, forgotten codes and wet fingers, which is closer to how doors actually fail in practice. If the dial mechanism proves durable and the charge claim holds in independent testing, it could simplify the support burden that has followed battery-powered entry hardware and make always-connected access control more plausible for mainstream households.
