Smart Locks and Keyless Entry: No More Keys, No More Worry
Unlock your door with a code, an app, your fingerprint, or just by being near it. Let your kids in from school. Let the dog walker in while you're at work. Lock the back door from your office when you remember you forgot. Smart locks turn one of the oldest parts of your home into one of the smartest.
When was the last time you actually liked using your keys?
Keys get lost. Keys get copied. Keys get forgotten in the lock overnight. You hide spare keys under flower pots and tell yourself they're safe, even though every burglar knows the seven places to check. You hand keys to dog walkers and house cleaners and forget to ask for them back. You stand at the front door in the rain, juggling grocery bags, fumbling for the key ring you can't quite reach.
Smart locks fix this. They replace your old deadbolt with a modern keyless entry door lock that unlocks with a code, a phone, a fingerprint, or simply by being close to the door. No more hidden keys. No more spare key under the mat. No more wondering whether the kids locked the door behind them. Just a quiet, reliable lock that does its job and tells you what's happening at the front door.
What a Smart Lock Actually Does
A smart lock is a modern keyless deadbolt that replaces or upgrades your existing front door lock. Beyond just locking and unlocking, today's smart locks offer real conveniences that change how you use your front door every day.
Five Things a Smart Lock Does for You
Unlocks without keys.
Use a numbered keypad code, your smartphone app, your fingerprint, or even your voice. Most smart locks support multiple methods, so each family member can use whichever they prefer. Keys still work too, on most models, as a backup.
Gives every user their own code.
Each family member, plus regular visitors like a dog walker or cleaner, can have a unique code or app access. You see exactly who came in and when. If a code needs to be removed (your teenager loses their phone, the cleaner moves on), you can delete it in seconds from your phone.
Locks and unlocks remotely.
Realized you forgot to lock the back door after leaving for work? Tap the app and lock it from anywhere. Let in a contractor before you get home? Unlock the door remotely and watch them enter through your security camera.
Auto-locks behind you.
Set the lock to engage automatically after a few minutes if no one has locked it manually. Realized three blocks from home you can't remember if you locked the door? The auto door lock has already handled it. No more 'did I lock the door?' anxiety in the middle of the workday.
Tells you when someone enters.
Get an instant notification when a door is unlocked, which code was used, and at what time. Know the moment your kids get home from school, your delivery arrives, or your house sitter shows up.
Two Smart Lock Install Options: Retrofit or Full Replacement
Smart locks come in two main install styles. The right choice depends on whether you own or rent, whether you want to keep your existing keys, and how much hardware change you want.
Retrofit Smart Lock
Attaches to the inside of your existing deadbolt without changing the outside hardware.
Best for:
- Renters (no permission needed, removes without trace)
- Anyone who wants to keep their existing key for guests or backup
- Homes where the existing deadbolt is high quality and works fine
- Quick install with no hardware change visible from outside
Full Replacement Deadbolt
Replaces your entire deadbolt with a modern smart lock with a keypad or fingerprint reader.
Best for:
- Homeowners who want the modern visual look
- Homes with older or worn-out existing deadbolts
- Anyone who wants a keypad accessible from outside the door
- Higher security ratings (ANSI/BHMA grade certifications)
Our advisor's take
Renters and people who love their existing keys usually do best with a retrofit. Homeowners who want a clean, modern look and the highest security ratings usually do best with a full deadbolt replacement. Most homes benefit from professional smart lock installation either way — proper alignment, secure mounting, and integration with your panel and monitoring make the difference between a lock that works perfectly and one that's frustrating from day one.
How You Actually Get In: Keypad, App, Fingerprint, or Key
Different family members and visitors prefer different ways to unlock. The best smart locks give you all of them on one device.
Numbered keypad code.
Type a code on the push button door lock keypad and the door unlocks. Each user gets their own code, so you know exactly who came in. The simplest, most reliable method for daily use. Works even if the internet goes down.
Smartphone app.
Unlock the door from your phone using the lock's app. Useful for letting in visitors when you're not home, or for setting and managing user codes. Some locks also use Bluetooth proximity, automatically unlocking when your phone gets close.
Fingerprint reader.
Touch the sensor and the lock opens. Fast, contactless, and impossible to forget at home. Especially useful for kids who don't carry phones.
Key (backup).
Most smart deadbolts still include a traditional key slot as a backup, so you're never locked out if the battery dies or the keypad has an issue.
Voice command.
Through compatible smart home assistants, most smart locks can be locked by voice. (For security reasons, voice unlock is usually not supported by default.) Useful for adding to your nightly routine: "Lock the front door" before going to bed.
When Smart Locks Actually Help
The technology only matters if it solves real-world problems. Here's how smart locks change daily life for the homeowners who install them.
Working parents.
Get an instant notification when your kids arrive home from school. No more calling to ask if they got home safely. You just know.
House cleaners and dog walkers.
Give them their own code that only works on the days and times they're scheduled. No spare key under the mat. No forgotten copies floating around. Code can be deleted in seconds when service ends.
Deliveries.
Some delivery services have offered in-home delivery through smart locks, though availability varies by region and program. Even without that, you can unlock the door remotely when a package needs to be brought inside out of weather or porch theft.
Aging parents living alone.
If your elderly parent leaves the door unlocked at night, you can check from your phone and lock it remotely. Some smart locks for elderly parents include auto-lock to handle this automatically.
Vacation rentals.
Generate a unique code for each guest that activates on check-in day and expires on check-out. No meeting in person to hand off keys. No worry about copies floating around.
Travel peace of mind.
When you're traveling, you can verify the door is locked from anywhere, see when your house sitter arrived, and confirm that no one has tried to enter. A smart lock with monitoring integration alerts you and the monitoring center to any unusual activity, even when you're across the country.

Frequently Asked Questions
Yes. Modern smart locks from established manufacturers are reliable, secure, and easy to use day to day. The technology has matured significantly over the past several years. Battery life is typically 6 to 12 months on a single set of batteries. Connection reliability is strong with proper Wi-Fi or hub coverage. And every reputable smart lock includes a traditional key slot or other backup access method, so you're never locked out if the electronics fail. For most American homeowners, the daily convenience is significant and the reliability is on par with modern smartphones.
Reputable smart locks use strong encryption standards (typically AES-256, the same algorithm used by many secure online services). While no connected device is 100 percent secure, smart locks from established manufacturers are more resistant to the most common bypass techniques used on traditional locks (lock picking, bumping, key copying from photographs). The bigger real-world risk is weak passwords or codes — choose a strong, unique app password and avoid obvious keypad codes like birthdays or 1234.
It depends on the model and how you want to use it. Most work locally without internet for basic keypad and fingerprint access. To unlock remotely from anywhere or to receive notifications, the device needs a Wi-Fi connection (directly or through a hub). Many professionally installed systems include a hub that handles this connection reliably. If your Wi-Fi is unreliable, ask your advisor about options that include cellular backup.
First, you get plenty of warning. Smart locks send low-battery alerts well before they actually run out, usually weeks in advance. Battery life typically ranges from 6 to 12 months on standard alkaline batteries. Some specific models among the keyless entry door locks longest battery life category claim up to 18 to 24 months in advertised use, though actual life varies by usage frequency, the specific model, and environmental conditions. If a battery does fully die before replacement, most smart deadbolts include a backup option: a traditional key slot, an external battery contact you can briefly power with a 9V battery, or both. You'll never be permanently locked out of your home.
Many smart locks are designed for self-installation and a basic install can take about 30 minutes with a screwdriver. That said, the process often hits unexpected challenges: doors that don't shut squarely, old deadbolt holes that don't match the new hardware, alignment issues that cause the bolt to bind, or hub connection problems. Professional smart lock installation eliminates these issues and gets the device working right on day one. It also integrates the lock with your panel, monitoring, and other smart devices, which most DIY installs don't do.
Yes, smart locks work for renters. Retrofit models attach to the inside of your existing deadbolt without changing the outside hardware, so the landlord's lock and key are preserved. When you move out, you remove the device with no trace. We do recommend checking your lease before installation, especially in apartment buildings, but in most cases the retrofit option is renter-friendly with no permission needed.
Installation costs vary by the specific model, your existing deadbolt, and any additional integration with your security system. A simple replacement is typically straightforward. More involved installs (multiple doors, hub setup, integration with an existing security system, hardware adjustments) take longer. We provide specific costs during the free consultation based on your exact situation, so there are no surprises.
There isn't one universal best smart lock — the right model depends on your existing door, your priorities, and which features matter most. Some homeowners prioritize the longest possible battery life. Others want fingerprint access. Some want the cleanest visual integration with their door hardware. A few need the strongest physical security ratings (ANSI/BHMA Grade 1 or 2). Our advisors compare options across our vetted provider network and recommend the right specific model for your home and your goals, rather than pushing the same product to every homeowner.
