Door Locks Worth Buying: A Practical Guide to Smart and Keyed Security

The moment most people start shopping for door locks is oddly specific: a key goes missing, a roommate moves out, or a delivery driver leaves a package and you realize the front entrance has not been upgraded in a decade. The best door locks balance three things that rarely line up on their own: real physical strength, a convenience feature you will actually use, and an installation that matches the door you already own.

This guide focuses on connected deadbolts and keypad-style locks from well-known security brands, because that is where most upgrade decisions happen as of 2026. You will find a quick comparison, four checkable buying rules, six product write-ups, and a short list of mistakes that lead people to return a lock after a weekend of drilling.

Quick Picks

How to Choose

Start with the door and the bore

Standard residential doors are usually between 1-3/8 and 1-3/4 inches thick, with a 2-1/8 inch cross bore and a 1 inch edge bore. Measure these before you shop. If your holes match, installation takes about 20 minutes with a screwdriver; if not, you may need a drilling kit or a different lock. Also check backset, which is the distance from the door edge to the hole center, commonly 2-3/8 or 2-3/4 inches.

Look for a real security grade

ANSI/BHMA grades rate residential locks from Grade 3 to Grade 1, with Grade 1 the strongest. A good rule of thumb is to pick Grade 2 or better for exterior doors. The grade label matters more than any app feature, because a smart lock with a weak bolt is simply a convenient way to be less secure. Also check that the bolt is at least one inch long and that the strike plate uses screws of 3 inches.

Decide how you want to unlock it

Keypad codes suit families and short-term guests, a fingerprint reader suits anyone who hates remembering codes, and an app or voice assistant suits people who like remote control. Always keep a physical key or a backup method. As a rule, avoid any lock without an emergency option such as a key cylinder or a terminal for a 9-volt battery, since dead batteries happen to everyone eventually.

Plan for power and connectivity

Most smart locks run on four AA batteries, and a low-battery warning should arrive weeks before failure. Wi-Fi models talk to your router directly, while Bluetooth models often need a hub or your phone nearby. If your router sits far from the front door, check signal strength there first. Read the support terms too, because locks with ongoing software updates age better than those left behind.

Before you buy, walk to your door and check three things: which way it swings, whether the frame is solid wood or metal, and whether the existing bolt throws into a reinforced strike. These checks take two minutes and prevent most of the returns people make after finding a lock does not suit their door. The write-ups below describe each lock only by what its name states.

Our Picks Reviewed

Schlage Encode Smart Wi-Fi Deadbolt

Schlage is among the best-known residential lock names, and this model is described as a smart deadbolt with built-in Wi-Fi. It is aimed at people who want remote access without adding a separate bridge.

• Pro: Wi-Fi in the name means the lock can join your home network directly, which simplifies setup compared with systems that depend on an add-on hub.
• Pro: A deadbolt format fits the standard cross-bore many exterior doors already have, so upgrading often means swapping hardware rather than modifying the door.
• Con: Wi-Fi locks rely on your router and a stable signal, so a spotty connection near the front door can slow remote commands.

Skip it if you want a purely mechanical lock with no batteries or app, or if your door uses a unique non-standard prep.

Yale Assure Lock 2

Yale is another established brand, and the Assure Lock 2 name signals a second-generation product in a connected lock family. It targets buyers who want a modern keypad-style unit that looks clean on the door.

• Pro: A numbered generation suggests refinement over an earlier model, which is useful if you want a mature product line rather than a first release.
• Pro: A smart lock in this category typically adds code-based entry, so guests, cleaners, and family can enter without a shared physical key.
• Con: Different configurations exist within this line, so you need to confirm the exact connectivity option you are ordering before you pay.

Skip it if you want a traditional keyed knob, or if you prefer a design with a deadbolt-only look and no touch surface.

Kwikset Halo Wi-Fi Smart Lock

Kwikset sells locks through major hardware channels, and the Halo name pairs with Wi-Fi in this listing. It suits households that want app-based control from a brand they can find in stores.

• Pro: A mainstream hardware brand tends to mean easy availability of replacement parts, strike plates, and support information.
• Pro: Wi-Fi in the name suggests remote lock status checks and control without carrying a bridge device, which is handy when you want to confirm the door is secured from work or while traveling.
• Con: Smart locks need regular battery changes, and a Wi-Fi unit may drain them faster than a simple keypad model, so budget time for periodic maintenance.

Skip it if you rarely use apps or you want the simplest possible installation with only a key and a bolt, since a plain mechanical lock asks for far less attention.

August Wi-Fi Smart Lock

August built its name around smart lock products, and this one states Wi-Fi in the title. Brands of this type often appeal to buyers who want to keep their existing exterior look.

• Pro: A brand focused on smart locks usually keeps its software and app experience central, which helps if you value polish over hardware variety, and it can make day-to-day settings easier to find.
• Pro: Wi-Fi connectivity means you can check or change lock status from anywhere with an internet connection, which suits busy households and rental hosts.
• Con: Smart-first designs may feel less familiar to guests who expect a traditional keypad or a visible keyway, so explain the entry method before they arrive.

Skip it if you want a rugged, no-electronics deadbolt or you are uneasy relying on a phone to open your door, even with a backup option available.

Ultraloq U-Bolt Pro

Ultraloq is known for feature-heavy smart locks, and Pro marks the higher tier in the U-Bolt line. It appeals to shoppers comparing several unlock methods in a single device.

• Pro: A Pro designation within a family usually points to more options than the base model, which helps if you want flexibility to try different ways of unlocking the door before settling on one.
• Pro: Smart deadbolts in this class generally replace the existing deadbolt, so the exterior door stays structurally unchanged and the swap can be reversed later if needed.
• Con: More features mean more settings to learn, and some households only ever use one entry method, leaving the extras unused.

Skip it if you prefer simplicity, a long-established legacy brand, or minimal setup steps, because a leaner lock will be quicker to configure.

Schlage Camelot Keyed Entry Knob

Not every upgrade needs electronics. This Schlage entry knob is a keyed, mechanical option for a bedroom, side door, or secondary entrance, or for owners who want familiar hardware with nothing to configure.

• Pro: A keyed knob has no batteries, no app, and no Wi-Fi to fail, which makes it dependable for simple needs and easy to understand for guests.
• Pro: The Camelot name belongs to a long-running Schlage design family, which makes matching other hardware around the house easier.
• Con: A knob alone is not a deadbolt, so exterior doors usually need a separate deadbolt for stronger protection against forced entry.

Skip it if you need keyless entry, remote access, or a standalone exterior security solution for your main entrance.

Which One Fits

• Family with frequent guests: a keypad-focused smart lock such as the Yale Assure Lock 2 is easiest for shared codes.
• Remote-control fan: the Schlage Encode, Kwikset Halo, or August Wi-Fi units put everything in the app.
• Feature shopper: the Ultraloq U-Bolt Pro gives the most options to compare before you commit.
• Budget-minded and simple: the Schlage Camelot knob keeps things mechanical; compare it with the options in our guide to the best door locksets if you only need a handle and key.
• New desk setup in a home office: secure the entry first, then tidy the room with a desktop organizer.

Common Mistakes

1. Skipping the door measurements, then discovering the bore or backset does not match the lock.
2. Choosing by app features alone and ignoring the ANSI/BHMA grade of the bolt.
3. Forgetting a physical backup, then getting locked out after batteries die.
4. Installing a strong lock on a weak frame with short strike plate screws.
5. Sharing one permanent code with everyone instead of giving guests their own codes that can be removed.

FAQ

Are smart locks safe from hacking?

Reputable brands use encryption, but no connected device is perfectly immune. Use a strong code, keep the firmware updated, and avoid obvious codes such as birth years.

Do I need a deadbolt or is a knob enough?

Exterior doors benefit from a deadbolt because the bolt extends into the frame. A knob lock alone is better kept for interior or secondary doors.

Can I install a smart lock myself?

If your door already has standard holes, most buyers manage it in under half an hour with a screwdriver. Doors without standard holes may need a professional.

How long do batteries last?

That depends on use and connectivity, but many households replace them once or twice a year. Pick a lock with an early low-battery warning.

What is the difference between a lock and a handle set?

A lock secures the door, while a handle set may be decorative or non-locking. Our overview of door locksets explains the knob and lever options in more detail.
