The eufy Smart Lock C30 is the cheapest way on this list to put a keypad and Wi-Fi on a door, at $79.99 on eufy's US store. Wi-Fi is built in, so the eufy Security app can control the lock from anywhere, send real-time notifications and keep an event history without a bridge. Auto-Lock secures the door on a timer, and a wrong-try lockout pauses the keypad after repeated bad codes. Eufy says it fits most standard deadbolts and installs in about 15 minutes without drilling, and it rates the lock IPX3 for temperatures from -22°F to 158°F. The compromises are power and entry options: it takes 4 AA batteries, not included, for up to 5 months, the shortest figure here, and there is no fingerprint reader. Eufy sells the C33 with fingerprint entry for $169.99 if you want one. We compared documented features and published prices.
