Picking a smart lock for your front door means choosing between fancier unlock tech and years of proven reliability, and the Best Overall, Best Budget Pick, Most Reliable Long Term, Best for DIY Home Assistant Setups, and Best Looking, Lowest Profile categories below each solve a different version of that trade-off. After digging through owner reports and community discussions, one lock kept coming up as the pick people switch to and never look back from: the Aqara U400. It works locally even when a company's cloud goes down, which turns out to be the single biggest complaint about smart locks in general. Below I break down exactly who should buy each pick, and who should skip it for something else.

This is for buyers who want the newest unlock tech without giving up reliability when the internet or a company's cloud servers go down. It fits homeowners already invested in HomeKit, Alexa, Google Home, or Home Assistant who want one lock that plays nicely with all of them. If you'd rather stick with a company with decades of hardware track record, look at the Schlage Encode Plus instead.
I love that this lock keeps unlocking my door over Zigbee and Matter even during outages, something owners of the Schlage Encode Plus and other WiFi dependent locks can't count on. The UWB hands free unlock is genuinely fast, faster in practice than the phone in pocket delay some competing locks are known for. Battery life stretches for months on a single charge, and the fingerprint, touchscreen, NFC, and physical key options mean I'm never locked out with just one method. Compared to the Schlage Connect BE469ZP, the U400 adds hands free entry and a modern touchscreen, though it asks a little more from your smart home hub setup.
Yes, if you want the most future proof unlock experience and don't mind a slightly fussier companion app. Skip it if you want a company with a long, uninterrupted product history, in which case the Schlage Encode Plus is the safer long term bet.

This is for buyers who want a smart lock that won't strain the budget and still want the peace of mind of a normal keyed deadbolt as backup. It suits anyone already running a Z-Wave hub like SmartThings or Home Assistant who doesn't need flashy extras. Buyers chasing the newest unlock tech should look at the Aqara U400 instead, since this lock keeps things simple.
At under $160 this is the cheapest lock in this roundup by a wide margin, undercutting the Schlage Connect BE469ZP by nearly $60. It still functions perfectly as an old fashioned keyed deadbolt, which matters if the electronics ever fail. Battery life is long as long as it's installed without binding, and it pairs cleanly with SmartThings, Vera, and Home Assistant. It won't wow anyone with looks or features, but it does the core job without drama.
Yes, if price and a reliable keyed fallback matter more to you than smart home polish. Consider the Schlage Encode Plus instead if you want WiFi built in and don't mind paying nearly double.

This is for buyers who want years of trouble free operation more than they want cutting edge features. It's the pick for iPhone and Apple Watch owners who want tap to unlock without fuss. If local, cloud free control matters more to you than built in WiFi, go with the Schlage Connect BE469ZP instead.
Owners describe years of flawless use with this lock more consistently than with any other pick here, including the Level Lock Pro, which has a rockier reliability record. The Apple Home Key tap to unlock is simple and dependable, and I can manage up to 100 access codes right from the app. Build quality feels noticeably sturdier than the budget end of this list, and the built in WiFi means no separate hub purchase like the Schlage Connect BE469ZP requires. The motor is a bit noisier than I'd like, but that's a minor gripe next to how solid it feels overall.
Yes, if a long, boring, trouble free ownership experience is your top priority. Skip it if you want the newest unlock methods, where the Aqara U400 pulls ahead.

This is for the DIY Home Assistant crowd who wants a deadbolt with zero cloud dependency and full local control through a Z-Wave hub they already own. It's the right call if you've been burned by a cloud outage before and never want to repeat it. If you don't already own a Z-Wave hub, the Schlage Encode Plus is the easier out of box choice since it has WiFi built in.
This lock runs entirely on local Z-Wave with no cloud in the loop, unlike the Schlage Encode Plus which leans on the Schlage Home app and WiFi. Multiple owners report years of rock solid operation in Home Assistant setups, and it pairs well with a non-locking handle for a simple two point entry. It's also nearly $130 cheaper than the Level Lock Pro, with none of that lock's reliability question marks. The only real catch is you need a Z-Wave hub or bridge, which not everyone starting out already owns.
Yes, if you already run a Z-Wave or Home Assistant setup and want a deadbolt that never depends on someone else's servers. If you don't want to buy a separate hub, go with the Aqara U400 instead for out of box smart home support.

This is for buyers who care most about looks and want a lock that vanishes into the door instead of announcing itself. It fits Apple Home Key users who still want that hidden profile. Buyers who prioritize dependability over aesthetics should choose the Schlage Encode Plus instead, since this pick's reliability record is more mixed.
Nothing else here disappears into the door the way this one does. It's noticeably smaller than bulkier options like the Schlage Connect BE469ZP, with zero visible hardware bulk inside or out. Apple Home Key, NFC fobs, and touch to unlock cover most unlock preferences, and the standalone bolt option skips extensive door measuring. That said, reliability is genuinely split here: some owners get years of flawless use while others have been locked out entirely, a risk you don't run with the Schlage Encode Plus.
Yes, if a low profile look is your top priority and you're willing to keep the battery exercised. If reliability worries you more than looks, the Schlage Encode Plus is the steadier choice.
Reliable for years across Wi-Fi, Z-Wave, and Zigbee versions with handy DoorSense status, though the phone in pocket unlock delay feels a step behind newer locks.
