Ring unveils $249 smart lock with hand-crank backup power for 2027 launch

Ring plans to release a new Smart Lock priced at $249, featuring a hand-crank mechanism that generates emergency power via a small motor and supercapacitor. A few turns of the crank produce about three volts, enough to run the lock's fingerprint reader, keypad or app connectivity for roughly 30 seconds. The device otherwise runs on a battery Ring says lasts a year per charge, and will ship in Black, Silver and Brass finishes sometime in early 2027.

Ring unveils smart lock with hand-crank backup power

Ring, Amazon's video doorbell company, has launched its first smart lock, featuring a manual power dial that lets users crank the device back to life if its battery dies. Founder Jamie Siminoff said he developed the feature after worrying about getting locked out of a rarely used vacation home due to a dead battery. The lock also supports entry via fingerprint reader, touchscreen keypad, the Ring app, or Alexa, and its battery is expected to last about a year.
