Smart Locks: Check Door Fit, Entry Methods and Connections

Illustration of a deadbolt surrounded by the ways to open it — key, fingerprint, keypad, and phone tap

Before buying a smart lock, check whether it fits the door, how people will enter and which functions reach your home systems. A platform badge does not establish remote guest-code management or a way in when the battery dies.

The table compares dated research records. Its support labels describe documented connections and limits, not security quality or hands-on results.

Which of these works with your home?

Don’t see the exact model you own? Two options, and they’re different:tell us and we’ll add it to the research queue (free), or get aSetup Check — a personalized, human-checked report that researches your whole list, including products we haven’t profiled yet.

Start with the existing door and key

The August Wi-Fi Smart Lock and SwitchBot Lock Ultra fit inside compatible doors while retaining the exterior deadbolt and key. The Aqara U200 also uses an existing cylinder, but its measurements and emergency-key requirements need checking.

A retrofit design is not permission to install it in a rental. Confirm the property owner’s requirements and who must retain access. Our rental lock guide covers those checks.

Level Lock Pro hides inside the door but replaces the deadbolt and includes its own keys. It does not preserve an existing key simply because it looks familiar. Schlage Encode Plus, Sense Pro, Yale Assure Lock 2 Plus and eufy FamiLock S3 Max are replacement designs too.

Name the entry function you need

Separate app control, keypad codes, fingerprints, phone tap and hands-free entry. Do not assume that a biometric function in the maker’s app is available through Matter or another platform.

Apple Home Key is tap-to-unlock using a compatible iPhone or Apple Watch. Home app support alone does not establish it. The Sense Pro and Aqara U400 also document hands-free entry with qualifying Apple devices and a Thread-enabled Apple home hub; check those requirements separately from tapping.

For guest access, confirm whether you can create, schedule, change and revoke codes from away. Remote lock control does not establish those operations. The short-term rental guide explains what to ask.

Count the required equipment and services

A bare SwitchBot lock and the Vision Pro Combo are different purchases: the combo includes the hub used for remote access. Aqara U200 needs a Thread border router for its platform connections. Level’s remote route needs the documented Thread setup or a separately sold Level Connect bridge, and its keypad is another accessory.

Yale’s Wi-Fi and Bluetooth-only configurations differ. The Wi-Fi model’s Alexa and Google listings do not establish every function there. Its Apple Home route should not be described as universally cloud-based just because Wi-Fi is present.

“No subscription for the lock” also needs a scope. Lockly Visage Zeno has free limits on access-sharing features that a paid tier raises. The eufy FamiLock’s optional video membership does not establish coverage for the lock camera; local video storage requires a HomeBase 3. Read those conditions before treating the hardware price as the whole cost.

Plan maintenance and backup entry

Maker-rated battery life varies by model and conditions. It does not predict how many months your installation will run. Rechargeable locks still need charging and may use separate backup or keypad cells.

The Encode Plus and eufy FamiLock include mechanical keys. Yale Assure Lock 2 Plus and Sense Pro are key-free and use different emergency power methods. Keep the required key or power source accessible from outside, along with the entry code where needed. Our dead-battery guide gives model-specific conditions.

Use the compatibility checker for your exact lock and home systems. Resolve any required feature marked unconfirmed before relying on it for entry.

Frequently asked questions

Do smart locks require a subscription?

Read the exact function and model. Core locking is subscription-free on many models here, but paid access-management limits and optional video services exist. Hardware, hubs, batteries and accessories also contribute to the cost.

Can a renter install a retrofit lock?

A retrofit may retain the exterior key, but it does not establish permission to change the door. Confirm approval, fit and restoration requirements before buying.

Does Apple Home support mean Apple Home Key?

No. Home app control, tap-to-unlock and hands-free unlock are separate functions with different requirements. Check the exact model and connection route.

How long will the batteries last?

Our profiles give dated maker claims, not measured battery-life comparisons. Plan replacement or charging around the manual and actual use, and know the backup entry method.
