Ring Smart Lock Puts Your Door on Amazon Sidewalk

Ring priced its first smart lock at $249 and put a hand crank on the front, with U.S. sales aimed at the first quarter of 2027. The company says a few turns of that dial restore enough power to open the door after the battery dies. Remote locking, status checks, and PIN syncing do not ride your home Wi-Fi. They ride Amazon Sidewalk, a shared mesh built from nearby Echo speakers and Ring cameras.

That split is the product. The crank is a short burst at the door. The network choice is what decides whether the app still works when you are not standing there.

A Few Turns Buy Seconds, Not a Full Charge

Amazon’s write-up of the lock leads with a power dial and four ways in: a fingerprint reader, a backlit keypad, the Ring app, and Alexa. There is no keyhole. The lock fits a standard single-cylinder deadbolt and uses Ring’s Quick Release Ultra Battery Pack, so installers do not run new wiring. Jamie Siminoff, Ring’s founder and chief inventor, has said that pack should last about a year, with a low-power alert in the app.

The dial does not refill that pack. In briefings, Ring described a small motor and a supercapacitor that hold power for 10 to 30 seconds after you crank, long enough to use a fingerprint, a code, the app, or Alexa at the door. Siminoff has put a number on the crank itself: about five to 10 turns, depending on how far and how fast you twist, until a light goes green. He has also said dumping that trickle into the main pack would be like “a garden hose in an Olympic-sized swimming pool.”

Almost everything in our lives today is digital, yet we still carry around little pieces of metal in our pockets. That’s because of smart lock anxiety. A lock has to work every time, and until now, a dead battery could leave you locked out of your own home.

He has told interviewers the idea showed up while he was choosing a lock for a house he expected to sit empty. “I struggled because this particular house will get used very little, and I know the freaking battery will die on it,” he said. He has also said none of the lock’s features needs a Ring subscription. Unlocks still happen on the device, so a dead Wide Area link does not, by itself, brick the door if you are there to crank it.

Yale and Schlage Still Carry a 9-Volt Jump

Keyless locks have been solving dead batteries for years, just not with a generator in the thumb-turn. Yale’s key-free models, including the Nest x Yale lock, tell owners to 9-volt battery on the exterior contacts and enter a code while holding it there. Schlage’s Encode line keeps a mechanical key and skips the 9-volt jump. Some newer Schlage hardware uses a USB-C port instead. August’s retrofit locks leave the original key cylinder in place, so a house key still works when the gadget dies.

DEAD-BATTERY BACKUPS

Siminoff’s jab at those backups is practical, not theoretical. A 9-volt terminal or a USB-C port does not help at 1 a.m. if you did not pack a battery or a cable. The crank removes that extra object. It does not remove the need to be at the door. If you are across town when the pack dies, the dial cannot open anything. The app path is a different radio.

Does the Ring Smart Lock Work Without Wi-Fi?

Yes for day-to-day remote control, as long as Amazon Sidewalk reaches the door. Amazon says remote locking, status updates, and PIN syncing run on Sidewalk, a shared network powered by nearby Amazon devices, so those jobs do not depend on the home router. Local unlocks still sit on the lock itself. The design assumes you live somewhere with adequate Sidewalk coverage. Amazon also warns that coverage may vary by location and can change or drop out.

Eligible Echo speakers and Ring cameras act as gateways, or bridges. A Sidewalk endpoint can roam onto any nearby bridge, which then uses a thin slice of that home’s internet to reach Amazon’s servers. The lock is the endpoint. Someone else’s Echo, or your own, is the bridge. That is how Ring can claim the lock stays reachable if your Wi-Fi flakes, and why a house with no nearby Amazon hardware is a weaker fit.

The same announcement that sells “control from anywhere” also tells buyers to approximate Amazon Sidewalk coverage before they count on the app. The lock is listed for the United States only. No other countries have been named for it.

Coverage Depends on Someone Else’s Echo

Sidewalk launched as an opt-out mesh on compatible Echo and Ring gear. Ring says owners can turn it off in the Control Center inside the Ring app. Amazon’s developer docs put a hard speed limit on what a bridge may share: an 80Kbps Sidewalk gateway bandwidth cap, described as about 1/250th of a typical 4K video stream. The data cap is set at 0.15% of average U.S. household internet use, which Amazon says is less than streaming about 10 minutes of 4K video.

SIDEWALK LIMITS ON THE LOCK

• The radio: The lock skips home Wi-Fi and talks through nearby Echo and Ring bridges.
• The cap: Each gateway is limited to 80Kbps toward Amazon’s Sidewalk server.
• The share: Sidewalk is capped at 0.15% of average U.S. household internet use.
• The map: Coverage varies by address, and Amazon says it can be interrupted.
• The switch: Ring owners can disable Sidewalk from the app’s Control Center.

A front door is a low-bandwidth job, so 80Kbps is plenty for a lock command. The weaker point is density. Sidewalk is only as good as the bridges around you. In a subdivision stacked with Echo Dots, remote lock and unlock should feel ordinary. On a dark lot with no Amazon hardware for a long walk, the app’s “from anywhere” pitch thins out, even if the crank still works when you get home.

The crank is the detail people clock first. It reads like a wind-up toy on a $249 deadbolt, which is funny until you notice what it is for: a few seconds at the door, not a year of charge, and not a substitute for a mesh most households never turned on on purpose.

Matter and Apple Home Are Not on the Spec Sheet

Ring did not announce Matter, Apple Home, or Home Key for the lock. Siminoff said Ring would rather let Alexa carry those links, because Alexa already talks to a pile of other locks.

We probably won’t do anything directly as Ring, because it’s more the Alexa integrations, because Alexa already has a lot of lock integrations and other stuff, so we’ll kind of let Alexa sort of lead the way on that.

Access rules live in the Ring app. Amazon’s example is a dog walker who can enter every Tuesday from 2:00 to 3:00 p.m. and not outside that window. Temporary codes can expire on a timer. Voice control is through Echo speakers and Alexa. Activity shows up in the Ring feed next to doorbells, cameras, and alarms. If your house already runs on Alexa, that is a straight line. If it runs on Apple Home, you are unlocking through Ring’s app as you walk up, not with the wallet key other deadbolts have spent years chasing.

Siminoff has been blunt about keys. “If you have to have a key, it’s like, well, why have a smart lock?” he said. The Ring answer is to delete the keyhole and keep a generator in the dial. The trade is a lock that is more Amazon than it is a generic Matter endpoint.

When Does the Ring Smart Lock Go on Sale?

Ring says the lock will be sold in the United States in the first quarter of 2027, in black, silver, and brass. It is not for sale now. Amazon’s own disclosure is the constraint that matters: the Smart Lock has not been authorized as required by the rules of the Federal Communications Commission, and it may not be offered for sale or lease until that authorization is obtained. Specs can still move before a ship date. Buyers can sign up for updates on Ring’s product page.

WHAT WE KNOW

• The price: Ring has set the lock at $249.
• The window: U.S. availability is aimed at the first quarter of 2027.
• The radio: Remote features are specified on Amazon Sidewalk, not home Wi-Fi.
• The pack: Day-to-day power is a replaceable Ring battery pack, about a year per Siminoff.

WHAT IS UNCONFIRMED

• FCC timing: Amazon has not said when authorization will land.
• Matter later: No Apple Home or Matter support was announced; Siminoff pointed at Alexa instead.
• Other countries: No international sale has been named for the lock.
• Exact crank count: Amazon says a few turns; Siminoff has described five to 10.

The cameras that landed beside the lock do not wait on that filing. They are the half of the announcement you can actually buy.

The $249 Deadbolt Still Needs a Camera

The lock has no camera. Ring says you pair it with a doorbell or with the new “Retinal Vision 4K” cameras that first showed up a year ago. On October 7, 2026, Ring put four new Retinal Vision 4K cameras plus a pan-tilt indoor 2K model on the site. That is five new cameras in one dump, with power options that run from a plug to Power over Ethernet.

NEW RING CAMERAS

The Indoor Cam 4K adds dual-band Wi-Fi 6 and a shutter that physically blocks the lens. The pan-tilt 2K uses computer-vision motion detection to keep pets and people in frame, then kills both the camera and the microphone when the shutter closes. Floodlight and Spotlight 4K Plus models are on preorder in the U.S. and several European markets; the Outdoor Cam 4K Plus adds Japan to that preorder list. The pan-tilt 2K also went on sale in Australia and New Zealand. The lock did not.

A buyer who wants a keyless door and a face at the porch is looking at the $249 lock plus at least one more Ring device, and at Sidewalk coverage on the street. Ring opened those camera carts on October 7. The deadbolt is still waiting on the FCC, and on whatever Sidewalk signal actually sits at the address on the order form.
