Electronic Door Locks for Home Entry: Keypad and Smart Models Explained

The groceries are in both arms, the keys are somewhere at the bottom of a bag, and it is starting to rain. That small daily frustration is what pushes many homeowners toward an electronic door lock, which replaces or supplements a metal key with a keypad, a fingerprint reader, a phone app, or a combination of them. The best of them still work when the power or the internet is down, which is the first thing to check.

This guide explains how electronic locks differ, what to measure on your door before ordering, and how six well-known models fit different homes. Product notes stick to what the names reveal, because specifications vary by version. As of 2026, many electronic locks fit existing deadbolt holes, so replacing one is often a screwdriver job rather than a carpentry project.

Quick Picks

How to Choose

Decide how you want to unlock

Keypads are the most universal because guests and cleaners can use a code without a phone. Fingerprint readers add speed but fail with wet or dirty fingers. Phone apps and Bluetooth unlocking are convenient but depend on battery life in the phone. A good rule of thumb is to choose at least two methods, including one that works without any app, so a dead phone does not lock you out.

Confirm the fit on your door

Most residential doors are 1-3/8 to 2 inches thick, and standard locks use a 2-1/8 inch bore with a 2-3/8 or 2-3/4 inch backset. Measure before buying. Check whether the lock replaces the full deadbolt or just the interior half, since retrofit designs keep your existing key cylinder and exterior hardware. Also confirm that the door and strike plate are solid, because the lock is only as strong as the frame.

Look at power and backup access

Most models run on four AA batteries and typically offer low-battery warnings weeks ahead. Look for a way to give emergency power from the outside, such as a 9-volt terminal, and for a physical key backup if you want one. A lock without any fallback is a risk if the batteries drain while you are away.

Check security grading and connectivity

Look for ANSI/BHMA Grade 1 or Grade 2 certification, with Grade 1 being the toughest. For connected models, look for encrypted communication, two-factor sign-in for the app, and activity logs. Decide whether you want a built-in Wi-Fi radio or a separate bridge, since built-in Wi-Fi drains batteries faster but needs less equipment.

Installation is usually simple, but plan for it. Most retrofit and full-deadbolt models need only a Phillips screwdriver and about thirty minutes, while a lock that replaces both the exterior and interior hardware demands careful alignment of the latch and the strike. Test the bolt with the door open, then closed, before you rely on it, and keep the door ajar while programming the first codes so a mistake cannot lock you out.

Our Picks Reviewed

Schlage Encode Smart WiFi Deadbolt

The name spells out what it is: a smart deadbolt with Wi-Fi support. Schlage is an established lock brand, so this appeals to buyers who want connected access from a familiar name.

• Pro: Wi-Fi in the product name means it does not need a separate bridge to be controlled remotely.
• Pro: coming from a long-established lock maker reassures buyers about hardware reliability.
• Con: built-in Wi-Fi tends to use battery power faster than a lock without it, so keep spare AAs.

Who should skip it: owners with spotty home Wi-Fi at the front door, and anyone who wants a purely offline keypad.

Yale Assure Lock 2

Assure Lock 2 is the second generation of a familiar line from Yale. The name does not list features, so check which module or key type comes with each version.

• Pro: a second-generation design implies refinements over the original line.
• Pro: Yale is a long-time lock maker, so servicing and parts are widely available.
• Con: different versions of the same name can offer different connectivity options, so confirm which one you are buying.

Who should skip it: shoppers who do not want to compare variants to find the right one.

August Wi-Fi Smart Lock

August built its reputation on retrofit locks that fit over the interior side of an existing deadbolt. The Wi-Fi in the name tells you that remote control is part of the package.

• Pro: retrofit designs let you keep your existing exterior hardware and keys.
• Pro: Wi-Fi support means remote access and notifications without extra hubs.
• Con: because it works with your existing deadbolt, its strength depends on that deadbolt and your door frame.

Who should skip it: people who want a keypad on the outside of the door as a primary method.

Kwikset Halo Wi-Fi Smart Lock

Kwikset is one of the most widely sold lock brands, and Halo Wi-Fi Smart Lock describes a connected deadbolt. It is the mainstream retail option in this group.

• Pro: broad retail presence makes it easy to find and to get replacement parts.
• Pro: built-in Wi-Fi removes the need for a separate bridge.
• Con: as with any Wi-Fi lock, router outages can limit remote features.

Who should skip it: households that distrust cloud-connected devices.

Ultraloq U-Bolt Pro

The Pro in the name indicates a higher-tier version in the U-Bolt line. Ultraloq locks are known for packing multiple access methods into one device.

• Pro: multiple unlock methods offer backups if one fails.
• Pro: the Pro tier suggests more features than the base U-Bolt.
• Con: more features can mean more settings to learn and a bigger learning curve.

Who should skip it: shoppers who want a simple keypad with a single code.

Level Lock+

Level is known for hiding its hardware so the door looks nearly ordinary. The Plus in the name marks an upgraded variant of the compact design.

• Pro: a compact, discreet form keeps the original look of your door.
• Pro: suits renters and design-minded owners who dislike bulky exterior keypads.
• Con: a minimal exterior may mean fewer unlock options, so confirm how you will get in without a phone.

Who should skip it: anyone who wants a visible keypad for guests and service workers.

Which One Fits

Your household decides this more than the brand. Families with children benefit from a keypad, because kids can enter a code without carrying a key or a phone. Landlords and short-term hosts benefit from scheduled codes that expire on checkout day, which removes the chore of collecting keys. Single occupants who always carry a phone may be happy with an app-based lock that keeps the exterior looking unchanged.

Think about the door you are protecting. A back door that sees little traffic may be fine with a simple keypad, while a front entry facing a busy street warrants a certified high-grade bolt and a reinforced strike. Whatever you buy, keep a mechanical backup somewhere safe, such as a spare key with a trusted neighbor, so a dead battery or a failed connection does not become an emergency.

• Remote access without a hub: Schlage Encode, Kwikset Halo, or August Wi-Fi.
• Keypad-centered household: Yale Assure Lock 2.
• Many ways to unlock: Ultraloq U-Bolt Pro.
• Subtle look: Level Lock+.

Common Mistakes

1. Choosing an app-only lock with no backup way in.
2. Ignoring door thickness and backset, which causes fit problems.
3. Not replacing batteries until the lock fails.
4. Installing a smart lock on a weak frame or short strike plate screws.
5. Leaving the default admin code or sharing a master code with everyone.

Maintenance deserves a calendar entry. Replace batteries once a year even if the lock has not warned you, wipe the keypad with a soft cloth, and lubricate the bolt only with a dry lubricant approved for locks, since oil attracts dust. Review the list of stored codes every few months and delete any that belong to former visitors, contractors, or tenants. Check that the bolt extends fully into the strike when the door closes, because a door that has shifted with the seasons can cause missed latching.

Finally, think about security habits around the lock. A strong code avoids birthdays and repeated digits, and a guest code should expire when the visit ends. If the lock offers an auto-lock feature, a short delay of 30 seconds to a minute keeps the door secure without catching you in the doorway. Treat the lock as one layer, alongside a solid door, a sturdy frame, and good exterior lighting.

FAQ

What happens if the batteries die?

Most locks give low-battery warnings and have an external power terminal or a key backup. Replace batteries when warned.

Can an electronic lock be hacked?

Any connected device has some risk. Use strong app passwords, keep firmware updated, and pick locks with encrypted communication.

Will it work with my existing door?

Most fit standard doors, but measure thickness and bore first. For the matching exterior handle, read the handleset roundup.

Do I need Wi-Fi?

No. Keypad-only locks work offline, though remote features require connectivity. If your router sits far from the front door, a model that uses a small bridge or a different radio can be more reliable than a lock that depends on a weak signal at the edge of your range.

Can I give temporary codes to guests?

Yes, most models allow multiple codes with scheduling. If you also rely on a bag for your phone and keys, see the EDC sling bag guide.
