Securing Your Home: The Pros and Cons of Keypad vs. Keyless Entry

Jun 01, 2026|

Cost guide: A basic battery-powered keypad deadbolt starts around $50 and tops out around $100. Mid-range Wi-Fi smart locks with touchscreen and full app control run $130 to $250. Premium fingerprint smart locks and combo deadbolt-handle sets reach $300 to $400.

Key takeaways: Which features matter most for you?

Prioritize a keypad for simple daily entry without a phone or key.
Prioritize a fingerprint sensor for the fastest unlock or households where kids forget codes.
Prioritize Wi-Fi or smartphone control if you travel or share access with cleaners and contractors.
Prioritize voice-assistant integration if you already run a smart speaker.
Prioritize Bluetooth if you keep your phone on you and want hands-free entry without typing a code.

Keys are easy to lose, easy to copy, and easy to forget. A keyless entry door lock removes that everyday hassle. Instead of a metal key, you unlock the front door with a code on a touchscreen, a fingerprint on a sensor, a Bluetooth ping from your phone, a Wi-Fi command from across town, or a voice line to a voice assistant like Google Assistant or Amazon Alexa. Modern keyless entry systems and smart door locks have matured fast, pairing keyless entry with full smart-home compatibility, app control, and battery-powered installation that takes about 30 minutes on most doors.

This guide walks through the five keyless entry features modern smart locks offer, how safe each one is against hacking and code-guessing, the Vivint smart lock features that actually matter for home security, and how to pick the right setup for a rental, a homeowner DIY project, or a business front door.

Keyless entry door lock features

Most modern locks combine a few of these in one lockset. This table compares what each feature does, who it fits best, and which features the Vivint smart lock includes.

Keyless entry features at a glance

Feature	How It Works	Best for	Vivint Smart Lock
Keypad	Punch a 4-to-8-digit code on a touchscreen or button keypad. Popular keypad deadbolt locks include the Kwikset SmartCode (which adds Kwikset's SmartKey re-keying so you can swap the physical key cylinder in seconds) and the Schlage Encode.	Everyday entry without a phone or key. Easiest learning curve. Works during a Wi-Fi outage.	✓
Wi-Fi or smartphone	Connects to your home Wi-Fi for full remote control. Lock or unlock from anywhere, send time-limited codes, and get notifications when someone enters.	Homeowners who travel, manage a second home, or share access with cleaners, dog walkers, or contractors.	✓
Voice assistant	Lock or check status by voice through Google Assistant, Amazon Alexa, or Apple HomeKit. Most voice-assistant locks require Wi-Fi or a smart-home hub.	Households already running a smart speaker that want to add the front door to the full smart home routine.	✓
Fingerprint (biometric)	Place an enrolled finger on the biometric sensor. The lock matches the print and unlocks in under a second. The downside: It's easy for burglars to lift your fingerprint off a doorknob, glass, or even a high-resolution photo.	Hands-full entries, kids who lose codes, and households that want the fastest unlock.	✗
Bluetooth	Your smartphone or a key fob talks to the lock when you're within about 30 feet. Some unlock automatically; others ask you to tap a button in the app. The catch: it only works in range, so no remote unlock from work or while you're away.	Renters who want a stick-on retrofit, and anyone who keeps their phone on them anyway.	✗

Are keyless entry door locks safe? How to address 2 real risks

Yes, in most homes a keyless lock is at least as safe as a traditional deadbolt and often safer because of features like auto-lock and tamper alerts. The most realistic risks are two specific issues you can plan around: account compromise and code observation.

Risk 1: Account hacking and digital attacks

Pure remote hacking of a residential keyless lock is rare. The bigger smart lock concerns are usually weak setup, not break-the-encryption-style attacks. Reputable Wi-Fi locks use encryption between the lock and the app, the same standard used in online banking.

The practical attack surface is your smart-home account, not the lock itself. Reusing a weak password, skipping two-factor authentication on your smart-home account, or losing a phone with the unlock app open is what creates real risk. Treat the smart home account the way you'd treat your bank login.

Risk 2: Code observation and keypad smudging

Keypad locks have one physical weakness: a four-digit code that's used over and over leaves smudges. A burglar who watches a single entry, or studies the wear pattern on a keypad, can guess a frequently used code. Three habits address it:

Pick a longer code (six to eight digits if your lock supports it).
Wipe the keypad every time so you don't leave your fingerprint behind.
Use a touchscreen with a randomized "scramble" feature, which forces you to press extra digits before your real code so the smudge pattern hides the actual sequence.

More ways to reduce risk

Beyond the two risks above, two pieces of hardware reduce the overall risk further.

The deadbolt grade. ANSI grades a deadbolt's mechanical strength from 1 (highest) to 3 (basic), and for a front door you want ANSI Grade 1 or Grade 2 (ANSI publishes the certification standards).
The alarm tie-in. Pair the lock with a monitored alarm so any forced-entry attempt triggers a real-person response, not just a siren.

Vivint smart lock features that close the gap

The honest case for a Vivint smart lock isn't that it's harder to pick than a hardware store deadbolt. It's that the lock works with the rest of the security system over Z-Wave, so the locking decisions and the alarm decisions stop being separate things you have to remember. The features below are the ones that change daily behavior.

Vivint Smart Lock features

Feature	What It Does	Why It Matters
Unique user codes	Each family member, cleaner, or contractor gets their own code	You see exactly who unlocked the door and when
Time-limited guest codes	Issue a code that works only for a set window (one afternoon, three days, the duration of a vacation rental)	You don't have to remember to delete these codes because they expire on their own
Auto-lock on a timer	Lock the deadbolt automatically after a set amount of time	The "did I lock the front door?" worry goes away. Auto-lock is what closes the unlocked-door failure mode that The Zebra's burglary research ties to 36% of break-ins
Tamper alerts	The lock notifies your phone if someone tries to force it, jam the keypad, or remove the lock	Real-time notifications give you a chance to cll for help before the burglar is inside
Alarm system integration	Unlocking with your code can disarm the alarm; locking can arm it	One action has two protections
App control and notifications	Lock, unlock, or check status from the Vivint app; get notifications when someone unlocks the door	You can let someone—like a delivery driver—in without leaving a key under the mat

Best fit by setup: rental, homeowner, or business

The right keyless entry door lock depends on what your lease or building allows, what you can install yourself, and how many people need access. Three common setups, and the lockset that fits each one.

Which keyless entry setup is best for you?

	Renter	Homeowner	Small Business
Best Lockset	A Vivint smart lock if your lease allows a deadbolt swap (the existing lock is preserved and goes back on at move-out). If the lease prohibits lock changes, skip the swap and add Vivint door and window sensors plus a monitored alarm to the existing setup.	Wi-Fi keypad deadbolt or smart lock with full app control, paired with a monitored security system.	Wi-Fi keypad lock with multi-user access control, time-limited codes, and access logs.
What You Get	Either way, full Vivint home security with app control and 24/7 monitored response. The smart-lock path adds keyless entry on the front door; the no-swap path keeps the original key but still wraps the rest of the home in smart monitoring.	Remote control from anywhere, time-limited codes, voice control through Google Home, auto-lock, and tamper alerts.	Code-per-employee accountability, instant code revocation when someone leaves, and a log of every entry and exit for compliance.
Watch Out for	Lease language about "altering door hardware." A reversible Kwikset deadbolt swap is the most common middle-ground; ask your landlord in writing.	Door measurements, especially the backset (typically 2 3/8 or 2 3/4 inches). Most smart locks adjust to either, but confirm before buying.	Higher-traffic doors burn through batteries faster; budget for replacements every six to nine months instead of yearly.

Cost, installation, and battery life

Three practical concerns trip people up after the lock arrives: how much it really costs once installed, how easy installation actually is, and how often you'll be replacing batteries.

Cost ranges

A basic battery-powered keypad deadbolt starts around $50 and tops out around $100. Mid-range Wi-Fi smart locks with touchscreen and full app control run $130 to $250. Premium fingerprint smart locks and combo deadbolt-handle sets reach $300 to $400.

Bundled smart locks that ship with a monitored security system don't have a separate sticker price; they're folded into the package.

Finishes don't change the security but they do change the price slightly. The most popular options are satin nickel for traditional homes, matte black for modern homes, and oil-rubbed bronze for warm-tone hardware. If you're matching the new lock to existing door handle hardware (lever, knob, or handle set), most major brands offer all three finishes across the full range.

Installation: pro setup or DIY swap

The simplest path is professional installation. With Vivint, a technician handles the lock swap, app pairing, and security-system integration in one visit and confirms every device talks to the rest of the system before they leave. You don't have to pick the lockset, measure the door, or troubleshoot a Wi-Fi pairing on your own.

If you'd rather do it yourself (which we don't recommend), most keyless entry door locks install easily on a standard residential door. Battery-powered models replace your existing deadbolt with a Phillips-head screwdriver in 15 to 30 minutes; you don't need a locksmith for the standard swap.

Two things to confirm before you start: your door's backset (the distance from the edge of the door to the center of the lock hole) and that your existing door hardware uses a standard cross bore.

Battery life and backup access

Battery life ranges from a few months to about a year depending on the model and how active the wireless radio is.

Customers have shared on social media that Vivint's Kwikset keyless entry door locks' battery life lasts anywhere from six months to over a year.

AA-powered keypad deadbolts without an always-on radio are typically rated for about 12 months of typical use. Adding always-on Wi-Fi cuts that down to around three months under typical conditions, while Bluetooth-only or pure keypad models stretch closer to a year.

Most modern smart locks send a low-battery notification through the app a few weeks before the batteries die, and most include a physical key backup so you can still get in if the batteries die at the wrong moment. A few keypad lock series include a 9-volt battery jumpstart on the exterior contacts as a backup power option, although many newer Wi-Fi-enabled keypad models do not and rely on the physical key for backup instead.

How to pick the right keyless entry door lock

Start with the four questions that actually narrow the field:

Do you rent or own?
Do you want to keep a physical key as a backup?
Do you want voice control through Google Home, Amazon Alexa, or Apple HomeKit?
Do you want the lock to talk to a monitored security system?

Once you answer those, the list shrinks from dozens of options to two or three. From there, match the finish (satin nickel, matte black, oil-rubbed bronze) to your existing door hardware, confirm the backset, and check the warranty.

Frequently asked questions about keyless entry door locks

A few questions come up over and over from shoppers comparing keyless options. Here's what to know before you buy.

What is the best keyless entry door lock?

The best keyless entry door lock for most homes is a Wi-Fi-enabled keypad deadbolt with auto-lock, time-limited codes, and tamper alerts. That combination handles daily entry, guest access, and the unlocked-door failure mode in one device.

For renters, the best lock is a stick-on Bluetooth retrofit that mounts on the inside of an existing deadbolt and leaves the visible hardware untouched. For homeowners with a monitored security system, the best lock is one that integrates with the system so unlocking can disarm the alarm and locking can arm it. CNET and Wirecutter both rank Yale Assure Lock 2, Schlage Encode, and Kwikset Halo near the top of the keypad-deadbolt category.

What are the disadvantages of keyless door locks?

Three real disadvantages: the lock runs on batteries that have to be replaced every six months to two years; a Wi-Fi or Bluetooth lock depends on a working network, so an internet outage can disable remote features (though local entry still works); and a keypad's smudge pattern can leak a frequently used code if you don't wipe the keypad or change the code occasionally. None of these are dealbreakers, and a smart lock with a low-battery notification and a physical key backup avoids the worst-case lockout.

Are keyless entry door locks safe?

Yes. A reputable keyless entry door lock is at least as safe as a traditional deadbolt for most homes. Wi-Fi smart locks use AES-128 encryption (the same standard as online banking); Bluetooth locks rotate a new key with every use; and ANSI Grade 1 or Grade 2 deadbolts pass the same forced-entry tests as the best mechanical deadbolts. The realistic risks are smudging on a keypad, weak factory codes, and forgetting to lock the door, all of which a longer code, an auto-lock timer, and tamper alerts close down.

What locks do police recommend for doors?

Most police-department public-safety bulletins recommend an ANSI Grade 1 or Grade 2 deadbolt with a strike plate anchored by 3-inch screws, paired with a monitored security system that includes door and window sensors. For keyless locks specifically, the same advice applies: pick an ANSI-graded deadbolt, use a longer code (six digits or more), enable auto-lock, and tie the lock into a monitored alarm so a forced-entry attempt triggers a real-person response and not just a siren.
