Ring has announced a $249 Smart Lock with a built-in hand crank that can generate enough electricity 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 set a precise release date.
Ring has announced a $249 Smart Lock that uses a built-in hand crank to generate emergency power if its battery runs out, giving users a short window to unlock the door. The company plans to release it in the first few months of 2027, but has not confirmed a specific launch date.
The small wheel is built into the front of the lock. According to The Ambient’s report, turning it back and forth three or four times generates enough electricity to run the lock for around 30 seconds. During that period, users can operate the fingerprint reader, enter a keypad code, use the Ring app or unlock it through Alexa.
The mechanism includes a small motor and a supercapacitor. The report says a few firm turns produce around three volts, allowing the lock to operate normally for the brief emergency window rather than switching to a limited low-power mode. Ring says the built-in battery should last up to a year on a single charge; the hand crank is intended as a backup for when that battery is depleted.
The lock uses a single-cylinder deadbolt and does not require additional wiring. Ring plans to offer it in Black, Silver and Brass. The company has opened registration for people interested in the product, although a precise launch day and the timing of general availability have not been announced.
A Backup Without External Power
The hand crank addresses a practical concern with connected locks: users may worry about being unable to enter if the battery dies and they do not have a replacement battery, charging cable or other power source available. Ring’s approach provides a way to generate a short burst of electricity at the door itself, without relying on another device or an external power supply.
That could be relevant for people who want keyless access but are uneasy about depending on a battery. Ring founder Jamie Siminoff also sees possible use at places visited infrequently, such as remote cabins, according to The Ambient. The stated 30-second operating period is limited, however: the report describes it as enough time to use the lock’s normal access methods, not as a way to keep the device powered indefinitely.

How Ring Plans the Lock
The hand crank is part of a broader response to a familiar smart-lock problem: electronic access depends on a working power source. In this product, the main supply is a rechargeable built-in battery, which Ring says can last up to one year per charge. The crank is an emergency fallback rather than the expected way to power the lock day to day.
Ring’s announcement also included other upcoming home-security devices, including four 4K cameras and a Pan-Tilt Indoor Cam 2K. Those products are separate from the lock. The lock’s defining feature in the report is its mechanical crank, which uses movement to generate enough power for a brief period of electronic operation.
“Concerns about losing access when a smart lock runs out of power can put people off buying one.”
— Jamie Siminoff, Ring founder, as described by The Ambient

Release Date and Tests Remain Open
Ring has not confirmed an exact release date; the current window is the first few months of 2027. The Ambient reports that Siminoff hopes the product will arrive closer to January than March, but that is not a confirmed shipping date.
The available information also does not specify how the lock will indicate that its battery is depleted, how much force or time the crank requires in everyday use, or whether performance varies with temperature or wear. The report gives an estimated battery life and a stated emergency operating window, but no independent test results or longer-term reliability data. Details such as installation requirements beyond the single-cylinder deadbolt and the final terms of availability have not been provided.

Ring’s Planned 2027 Release
Ring’s current plan is to release the Smart Lock sometime in the first part of 2027 at a planned price of $249. The company has not announced a precise date, and interested customers can register their interest. Further information about availability, installation and operating details would clarify how the crank performs outside the company’s stated scenario.
