In Plain English
Both of these locks open with your fingerprint or a keypad code. The big difference is how they connect. The eufy has Wi-Fi built in, so it can talk to your phone from anywhere. The Wyze uses Bluetooth only, which works when you're near the door, like a wireless speaker that only plays when your phone is in the room.
Why it matters: if you want to lock or unlock the door while you're away, the eufy does that out of the box. The Wyze can't, but its batteries last longer and it has a slightly higher rating. The one thing to decide is whether you truly need remote access. If you do, choose the eufy. If you only lock and unlock at the door, the Wyze is a strong, simpler pick.
Quick Take
eufy Smart Lock C220 and Wyze Auto-Lock Bolt both bring fingerprint entry to the budget-to-mid smart-lock tier, backed by a keypad and companion app as fallback methods. eufy C220 pairs fingerprint recognition with built-in WiFi, so it talks straight to your home network with no separate hub. Wyze Auto-Lock Bolt pairs the same fingerprint convenience with Bluetooth-only connectivity, so app control works near the door but not remotely. The sections below walk through connectivity, keypad entry, install, battery, security and app ecosystem in turn, so you can weigh the real difference instead of the star rating alone.
| eufy Smart Lock C220 | Wyze Auto-Lock Bolt | |
|---|---|---|
| Rating | Solid, deep review base | Slightly higher, smaller review base |
| Unlock methods | Fingerprint, keypad, app | Fingerprint, keypad, app |
| Connectivity | Built-in WiFi | Bluetooth only (local app control) |
| Auto-lock | Check current listing | Yes |
Connectivity and Remote Access
This is the clearest functional split between the two locks. eufy C220 has WiFi built directly into the lock body, so it connects to your router on setup and gives you remote lock, unlock and activity alerts in the eufy Security app without buying anything extra. Wyze Auto-Lock Bolt is Bluetooth-only, which handles local app control and code management fine from nearby, but Wyze offers no gateway for it, so there's no remote lock or unlock away from home — only an emergency one-time code you can generate remotely in the app. If remote access matters and you want it working the moment the lock is on the door, that gap favors eufy.
Fingerprint and Keypad Entry
Both locks lead with fingerprint recognition as the headline convenience feature, backed by a physical keypad and app-based unlock as fallback methods. Owners on both locks report fingerprint recognition is fast in normal conditions and less reliable with wet, cold or dirty fingers — a limitation of fingerprint sensors generally, not specific to either brand. Both keep a keypad as the dependable backup when a fingerprint read fails, so neither leaves you locked out over a stubborn sensor. Check the current listing for each lock's stated fingerprint storage capacity if a larger household is sharing one door.
Installation and Door Compatibility
Both are designed as direct retrofits for a standard US deadbolt hole, so most owners install either lock in under an hour with a Phillips screwdriver and no locksmith. Measure your door's backset and thickness against each lock's specific compatibility range before ordering — a mismatch there is the most common return reason in this category, regardless of brand. See our full how to install a smart lock walkthrough for the general retrofit process both locks follow.
Battery Life
Both locks run on standard batteries with a low-battery warning through the keypad before they die. eufy C220's built-in WiFi radio draws more continuous power than a Bluetooth-only connection — eufy rates it at around eight months on eight AA batteries, while Wyze rates its Bluetooth-only Bolt at 10 to 12 months on four AA batteries. Neither lock leaves you stranded on a dead battery: the eufy includes a physical backup key, and the keyless Wyze has a USB-C port on the keypad for a brief emergency charge, so a flat battery is an inconvenience, not a lockout.
Security and Build Quality
Both locks carry a physical deadbolt mechanism behind the smart features, and the bolt itself is the more meaningful security measure than either lock's connectivity — eufy lists BHMA Grade 3 for the C220, so check each current listing for the specific grade. eufy brings a broader established smart-home product line spanning cameras and sensors, which shows up in owner reviews as general brand trust. Wyze carries a similarly large following across its own camera and sensor lineup. Neither lock's fingerprint or app layer is a substitute for a solid strike plate and door frame.
Ecosystem and App
eufy C220 works through the eufy Security app, and owners already running other eufy cameras or sensors get one unified app for the whole household rather than a separate lock-only app. Wyze Auto-Lock Bolt works through the Wyze app too, with the same one-app advantage for anyone already inside the Wyze ecosystem — though Wyze notes the Bolt doesn't support Wyze automations or Alexa and Google, whereas eufy lists Alexa and Google Assistant voice control for the C220. Neither lock's app-ecosystem advantage matters much if you're starting from zero brand loyalty — in that case the connectivity and battery differences above are the more useful tie-breakers.
Price Tier and Value
Both locks sit in the budget-to-mid tier of this hub's smart-lock range, priced well below fully WiFi-native premium deadbolts like Schlage Encode. eufy C220's built-in WiFi typically puts it slightly above Wyze Auto-Lock Bolt on price, reflecting the added radio hardware. Check the current listing for both, since pricing shifts, but the relative gap between them tends to hold fairly steady across most of the year.
Use Cases
eufy C220 suits a front door where you want fingerprint entry and remote access working immediately, without adding a second accessory. Wyze Auto-Lock Bolt suits a buyer who's happy with Bluetooth-only local control and doesn't need remote access, or who's already standardized on Wyze hardware elsewhere in the home. Neither is the wrong pick for a rental or a second door — both are simple enough that either one covers that use case comfortably.
Who Should Buy Which
Choose eufy Smart Lock C220 if you want fingerprint entry with remote access working out of the box, or you're already running other eufy smart-home devices and want one app for everything. Choose Wyze Auto-Lock Bolt if local Bluetooth control is enough, you like the longer rated battery life and keyless design, or you're already standardized on Wyze cameras and sensors elsewhere in the house. Both are legitimate budget-tier fingerprint locks — the honest choice comes down to whether you need remote access solved on day one.
eufy Smart Lock C220
eufy C220 holds the deeper review base of the two fingerprint-enabled locks, and its built-in WiFi means remote access works without an extra accessory purchase. See the full eufy Smart Lock C220 review.
Wyze Auto-Lock Bolt
Wyze Auto-Lock Bolt holds the slightly higher rating and includes a confirmed auto-locking function, at a price point that typically undercuts eufy's built-in WiFi convenience. See the full Wyze Auto-Lock Bolt review.
Going Deeper: Why Wi-Fi Locks Burn Through Batteries Faster
The battery ratings on this page tell a clear story once you line them up. Per the manufacturers' figures cited above, eufy rates the Wi-Fi C220 at around eight months on eight AA batteries, while Wyze rates its Bluetooth-only Bolt at 10 to 12 months on four AA batteries. That works out to roughly one AA a month for the eufy versus about one AA every two and a half to three months for the Wyze. In other words, the eufy gets through its batteries around two and a half to three times as fast.
The reason is how each radio spends its time. Bluetooth Low Energy was designed specifically to sip power. A 2012 study in the journal Sensors by Gomez, Oller and Paradells describes it as a low-power solution for control and monitoring applications, built for devices running on small batteries such as coin cells. Its key trick is that devices stay asleep by default and wake only periodically, with brief connection events that keep the radio's active time to a minimum.
How often a device talks makes an enormous difference. The same study calculated that a coin-cell-powered Bluetooth Low Energy device could last anywhere from 2.0 days to 14.1 years, depending on how frequently it communicates, with the long lifetimes reached when data is exchanged infrequently. A Bluetooth lock that only wakes up when your phone is nearby sits at the frugal end of that range.
A Wi-Fi lock has a different job. To accept a remote unlock command at any moment, it has to stay reachable on your home network rather than sleeping until someone walks up. That constant availability is exactly what gives the eufy its remote access and alerts, and it's also where the extra batteries go. Neither approach is wrong. You're choosing between remote access and fewer battery changes. Whichever you pick, keep a spare set of batteries at home, and remember each lock's backup: the eufy's physical key, and the USB-C emergency power port on the Wyze's keypad.
Verdict
eufy Smart Lock C220 and Wyze Auto-Lock Bolt are both well-evidenced, fingerprint-enabled locks in the budget-to-mid tier, and neither is a clear loser against the other. eufy C220's built-in WiFi gives it the edge for remote access on day one; Wyze Auto-Lock Bolt's slightly higher owner rating and Bluetooth-first design keep it a genuine value pick, especially for anyone already inside the Wyze ecosystem. Weigh the connectivity gap against your actual need for remote access before deciding. See best smart locks for the full field.
