Pros & Cons
Wyze Lock Bolt V2 (WLCKB2)
Pros
- +The cheapest lock here with genuine built-in Wi-Fi — no bridge, no hub, no subscription
- +Fingerprint reader is the standout: reviewers report sub-second, weather-tolerant reads
- +Keyed cylinder AND a USB-C emergency contact, which several $300 locks here do not both have
- +IP53-rated and runs 8 months on eight cheap AA cells
Cons
- −No Matter, no Thread, no Apple Home — it lives inside the Wyze app and Alexa/Google, and that is the whole ecosystem
- −The BHMA Grade 2 claim appears only on retail listings; Wyze publishes no certification listing to check it against
- −Eight AA batteries is a lot of dead weight and a lot of cells to buy
- −Wyze's history of app outages and security incidents is a real consideration for a device that guards your front door
eufy Smart Lock E30
Pros
- +Wi-Fi is genuinely in the lock — you are not buying a bridge afterwards, unlike most of eufy's older C-series
- +Both fallbacks covered: a keyed cylinder and a USB-C emergency contact
- +Fingerprints are held on the device, not uploaded, and eufy charges no subscription for lock features
- +Eight months on AA cells with no proprietary battery pack to source later
Cons
- −ANSI/BHMA Grade 3 — the weakest residential grade, and a real step down from the Grade 1 locks at $250-$350 here
- −The Matter support on the box did not work in PCWorld's testing across two different Thread hubs; treat it as unproven rather than a feature
- −No Apple Home Key, so iPhone users get app control but not tap-to-unlock
- −The fingerprint reader is the least reliable of the biometric locks in this set
