Best Smart Locks in 2027

The Aqara U100 leads our ranking, and the specs show why. It is rated Grade 3 for security and includes a deadbolt. That covers the first thing an exterior door needs. The lock body is zinc alloy with an IP65 rating, and the listing says it handles temperatures from -31°F to 151°F. That matters on a door exposed to weather.

Door fit reaches furthest at the top end. It lists a door thickness of 1.378 to 2.165 in and a backset of 2.362 to 2.756 in. The 2.165 in maximum thickness and 2.756 in maximum backset are the highest on our page. Thicker doors that turn away other locks may work here, so measure yours first.

Unlocking is the smart part. It reads up to 50 fingerprints, supports Apple Home Key, and takes a mechanical key as backup. Four AA batteries come included and last up to 8 months. Remote codes need an Aqara Zigbee 3.0 hub. The maker doesn't publish a warranty length or a cycle rating.

The TEEHO TE001 ranks second. It is a keypad deadbolt, not a connected smart lock, and the listing mentions no app. You enter a code to open the door. It holds 20 access codes for family and a temporary code for single-use guest entry. A one-time PIN deletes itself after use. That helps when guests visit.

Security is listed as Grade 3 and it includes a deadbolt. The listing describes aluminum alloy construction, an IP54 weather rating and anti-peeping code protection. It includes 2 keys and the warranty is 2 years. Weight is 1.76 lb. Door thickness and backset are not in our data, so check the maker's fit notes before buying.

Fit has one firm limit. The listing says it suits only 2-1/8 in (54mm) door holes and is not compatible with 38mm holes. Power comes from 4 AA batteries, which are not included. The listing claims up to 365 days of life and a red light warns when charge drops below 15%. Auto-lock can be set from 10-99 seconds.

The Kwikset Tylo ranks third, but it does not fit the keyword well. It is a keyed deadbolt and lever combo with no electronics listed. If you want app, code or fingerprint entry, look at the Aqara or Veise instead. If you want a plain, secure exterior set, it makes more sense.

On paper it covers the basics. Security is Grade 3 and a deadbolt is included. It fits doors 1.375 to 1.75 in thick, and the latch backset adjusts to 2.375 or 2.75 in with a twist during installation. That covers standard exterior door prep. It weighs 2.25 lb and comes with 2 keys.

The warranty is the standout. Kwikset lists a lifetime warranty, which is the longest term in our data, shared with three other models. SmartKey lets you re-key the lock yourself in seconds, useful after you lose a key. The box also holds round and square latch fronts and a drive-in collar. The maker doesn't publish a cycle rating.

The Estmoon set ranks fourth and, like the Kwikset, it is a mechanical lock with no electronics. You open it with a key outside and a thumb turn inside. It is sold as a pack of 2, so you get two lock sets for a front and back door. Every set is keyed alike.

Keys are where it stands out. The listing says one key opens every lock, and each set includes 12 identical keys. That is the highest key count among the models that list it. It suits a household that wants one key for every door. Weight is listed at 2 lb.

Security is Grade 3, and the listing gives a rating of 200,000 cycles. That ties for the lowest cycle rating among the seven models that list one. Door thickness is 1.375 to 1.75 in, backset is 2.375 to 2.75 in, and it needs a 2-1/8 in (54mm) bore hole. The maker doesn't publish a warranty.

The Veise VE017 ranks fifth and is the second connected lock among our top five. It opens with fingerprint, app, code, fob card or a mechanical key. The listing says the fingerprint reader verifies in under 0.2 seconds. Alexa and Google voice control need a G1 Gateway, so plan for that extra piece.

Access control is the strength. Through the KK Home app you can add users, pause or delete access, and read activity logs of every entry. Code options include one-time, guest and recurring codes. An anti-peeping feature lets you type extra digits around your PIN. Auto-lock is adjustable from 0 to 180 seconds.

Fit and basics are sound. It carries a Grade 3 rating and a deadbolt. Door thickness runs 1.375 to 2 in, which goes past the 1.75 in maximum most models list. Backset is 2.375 to 2.75 in. It weighs 2.25 lb and has a 2-year warranty. The 4 AA batteries are not included and last about 12 months.
