The short version
A good smart lock should make your home easier to use without making it less secure. The bar is simple. It should still be a real deadbolt under the smart parts. It should let you revoke a code without rekeying. It should work even when the Wi-Fi is down. And it should be installable on a standard residential door without a contractor. Most of the major brands clear that bar in 2026, so the question is mostly which feature set fits your household.
What a smart lock actually does for a Maryland homeowner
The first thing it does is delete the lost-keys problem. If your kid loses a key on a Bethesda playground, you do not need a same-day rekey or a panicked call to the locksmith. You delete the lost code in your phone and the lock no longer accepts it. The second thing it does is delete the spare-key-in-the-hide-a-rock problem. Anyone who needs short-term access (the dog walker, the cleaner, the neighbor watering plants while you are at the beach) gets a temporary code that automatically expires.
The third thing, often underrated, is the audit log. Every smart lock keeps a record of which code was used and when. For a busy Rockville household with multiple kids, an au pair, and a parent who travels, that log answers the question "did the boys get home from practice on time" without anyone needing to text.
What it does not do
A smart lock is not a substitute for a real deadbolt. The good ones are still a real Grade 2 or Grade 1 mechanical deadbolt with smart electronics added on top. The cheap ones, in our experience, are an electronics module bolted to a thin lock body, and they fail in the ways you would expect. If you remember nothing else from this post, remember that the electronics matter less than the deadbolt underneath.
A smart lock also does not improve your physical security if your door frame is weak. We see Maryland homes every week with a $300 smart lock installed on a hollow strike plate held by half-inch screws. That is a wide-open door. Smart-lock installs in our shop always include reinforced 3-inch strike screws. If your installer skips that step, ask why.
The four smart locks we install most often in Maryland homes
We are deliberately brand-agnostic, so this is not a commercial. These are simply the four we see most often on Maryland front doors and which ones we will recommend without reservation.
Schlage Encode
The Encode is the workhorse. Built-in Wi-Fi (no extra hub), works with the Schlage app and with most major smart-home platforms, and underneath the smart parts is a real Schlage BE489 Grade 2 deadbolt. It is our most-installed smart lock across Montgomery, Howard, and Frederick counties. The keypad is large and tactile, which matters for older hands and cold mornings. Battery life is about a year on average use.
Yale Assure (with Wi-Fi)
The Yale Assure is the closest direct competitor to the Encode and matches it on most features. It looks slightly more modern, with a lower-profile housing, and the touchscreen keypad is brighter and a bit faster than the Schlage tactile keypad. The Wi-Fi version is what you want. The Bluetooth-only version is fine but gets old fast when you want to send a code to someone while you are at work.
August (4th gen, retrofit-only)
The August is the only retrofit smart lock we install with confidence. It mounts on the inside of your existing deadbolt, leaving the outside completely untouched. That is huge for two situations. First, condo owners and Bethesda high-rise residents who cannot change the exterior hardware (HOA or building rules). Second, anyone with a high-end exterior knob set or restricted keyway who does not want to give up the brass. August handles both scenarios, and the auto-unlock-when-you-arrive feature is genuinely magical the first twenty times you experience it.
Level Lock+
Level is the high-end option. It is a smart lock that does not look like a smart lock at all. The electronics are entirely inside the lock body. From the outside, it looks like a traditional deadbolt. For homeowners who care about exterior aesthetics (Potomac estates, historic Annapolis homes, Olde Towne Gaithersburg), this is the only one we install. It is more expensive than the others, and the keypad is a separate accessory rather than built in, but the design is unmatched.
What we steer customers away from
We routinely advise customers against the lowest-end smart locks at big-box stores. They usually have weak deadbolt bodies (Grade 3 or below), short battery life, and the manufacturer drops support for the app within two or three years, leaving you with an expensive paperweight. If a smart lock costs less than a comparable mechanical deadbolt of the same brand, that is a signal the deadbolt itself is the part being shortcutted.
Installation and what to expect
A typical smart-lock install on a standard residential door takes about an hour. We arrive, confirm the door prep is correct (most modern doors are fine, some older Olney and Damascus homes need a strike plate adjusted or a backset corrected), remove the old hardware, install the new lock, and connect it to your Wi-Fi or hub on the spot. Before we leave, we walk you through the app, set up your first three codes, and reinforce the strike with 3-inch screws. A second door usually adds about thirty minutes.
Wi-Fi, hubs, and the boring parts
The Encode, Assure, and Level all have Wi-Fi built in (or available as an option). The August needs a small bridge plugged into a nearby outlet to be reachable when you are away from home. None of them require a paid subscription for the basic features (codes, auto-lock, audit log). Some brands offer optional cloud features for a fee. Skip those unless you have a specific reason. The free tier is usually all you need.
For homes with weak Wi-Fi at the front door (common in larger Potomac and Frederick homes with the router in the back office), we sometimes recommend a Wi-Fi mesh node or a smart hub that supports Z-Wave or Thread. That is a different conversation worth having on the phone before you buy.
Bottom line
A smart lock is one of the few home upgrades that pays for itself in convenience within the first month. The keys you stop losing, the texts you stop sending to confirm someone is home, and the lockouts you stop having all add up. Pick a real Grade 2 deadbolt with smart parts on top, install it on a reinforced strike, and you will not regret it.
