Keyless entry for under $100 is hard to beat. The eufy Security Smart Lock C220 is down to $99.99 at Amazon, $70 off its $169.99 list price — a 41% discount on a fingerprint deadbolt with Wi-Fi built in, so there’s no hub to buy.

- Sale price: $99.99
- List price: $169.99
- You save: $70 (41% off)
- Where: Amazon — price verified live on the product page
Why it’s a good buy
- Fingerprint unlock in under a second, plus keypad codes, app control, and two physical backup keys — up to 50 fingerprints and 100 passcodes stored.
- Built-in Wi-Fi means remote lock/unlock and notifications straight from the eufy app with no bridge or hub.
- 8-month battery life on standard batteries, IP53 weather resistance, and BHMA Grade 3 certification for durability.
- Pairs with the eufy video doorbell for a fuller front-door setup.
One caveat: the C220 doesn’t support Apple HomeKit, Matter, or IFTTT — it’s an eufy-app and Alexa/Google affair. If you’re already in that ecosystem, $99.99 is an excellent entry point to keyless living.
