Ring has announced a $249 Smart Lock with a built-in hand crank that can generate enough power to operate the lock for about 30 seconds if its battery runs out. The lock is planned for the first few months of 2027, but Ring has not announced a precise release date.
Ring has announced a $249 Smart Lock that can generate emergency power when its battery runs out, using a small hand crank built into the lock’s exterior. The company says a few turns will power the lock for about 30 seconds, giving users time to unlock it through its fingerprint reader, keypad, Ring app or Alexa.
The crank is designed as a backup for a depleted battery, rather than a regular way to operate the lock. According to the report by The Ambient, turning the wheel back and forth three or four times generates enough electricity for the short operating window. The mechanism includes a small motor and a supercapacitor; Ring founder Jamie Siminoff says firm turns generate around three volts.
Ring says the lock’s built-in battery should last up to a year on a single charge. The company has not published more detailed battery-life conditions in the supplied report, so that estimate should not be treated as a guaranteed duration for every household. The lock uses a single-cylinder deadbolt and does not require additional wiring. Listed finishes are Black, Silver and Brass.
The planned price is $249, with availability expected in the first few months of 2027. Ring has not given a firm launch date. The report says Siminoff hopes it will arrive closer to January than March, but that is not a confirmed release schedule. Customers can register interest, according to the report.
A Backup for Dead Batteries
A battery-powered lock can create a particular problem when its power runs out: the device meant to provide keyless access may become unusable at the door. Ring’s crank addresses that concern with a backup that does not rely on a spare battery, charging cable or external power source. It could be useful to people who worry about being locked out, though the reported 30-second window is intended to provide time to use one of the lock’s normal entry methods, not to keep it running indefinitely.
Siminoff also sees a possible use at remote cabins or other locations visited infrequently, according to The Ambient. In such settings, a self-generated emergency power source may be more convenient than keeping replacement batteries or cables available. That is a potential use described by the founder, not a verified performance assessment for particular locations or conditions.
The feature also speaks to a broader trade-off in connected home devices: convenience depends on power and electronics continuing to work. Ring is presenting the crank as a way to reduce one specific concern about smart locks. The announcement does not establish whether the design will change adoption, reliability or access during other kinds of failure.

How Ring Plans to Power It
Ring’s answer is a small wheel mounted on the front of the lock. When the battery is depleted, users turn it several times to generate electricity. The lock’s internal motor and supercapacitor store and supply enough power for roughly half a minute, during which the company says users can operate the fingerprint reader, keypad, app or Alexa.
The crank is one part of an upcoming Ring hardware lineup. The report also lists four planned 4K cameras: the Outdoor Cam 4K Plus, Spotlight Cam 4K Plus, Floodlight Cam 4K Plus and Indoor Cam 4K. Ring is also preparing a Pan-Tilt Indoor Cam 2K, described as having a base that rotates 360 degrees, tilts 175 degrees and automatically follows movement indoors. Those products are separate announcements; the lock’s emergency power system is the feature at the center of this development.
“The lock can generate around three volts with a few firm turns of the wheel.”

Release Date and Testing Details
Ring has not confirmed the Smart Lock’s exact release date. The reported launch window is the first few months of 2027; a preference for a date nearer January than March is attributed to Siminoff, not presented as a finalized schedule. The company has also not provided, in the source material, independent testing results or details on how the crank’s output may vary with use, handling or other conditions.
The report describes the lock’s normal entry options and expected emergency power duration, but does not explain what happens if a component other than the battery fails, or how the lock behaves after the 30-second window ends. Those details are not confirmed in the available information.

Ring’s Planned 2027 Launch
Ring is expected to provide further product and availability details before the planned launch in early 2027. Until it confirms a release date, the timing remains a window rather than a scheduled day. The company may also share more information about the lock’s operation, battery-life estimate and supported access methods as launch approaches. For now, the announced price is $249, and customers can register interest, according to The Ambient.
