Have you ever locked yourself out of your own home? How frustrating! There you stand, on the new doormat you just put out, staring at your keys through the window. So close, yet so far away! What do you do?
Do you try to break into your own home? Call a friend that has a spare key? Or do you wait around for a locksmith to show up and let you back in?
Door locks secure our belongings and loved ones, but they can also be incredibly inconvenient. Luckily, door locks have gotten smarter, along with many other new smart home technologies.
Smart door locks provide the same security and function as a traditional door lock but with added features to fit our modern lives. They still rely on a deadbolt to keep your door safely locked, but with added conveniences. They control the lock from your smartphone with smart assistants, passcodes, fingerprint readers, fobs, and above combinations. With a smart lock installed, you're never truly locked out of your home.
Smart door locks also make it possible to lock and unlock your door remotely. Depending on the lock you choose and how you configure it, you can check your door from your smartphone or even verbally ask your smart speaker if it's locked.
There are a variety of smart lock options available, all with unique features and requirements. Take a moment to think of some features that are important to you. For example, you might prefer a smart door lock that works with your existing deadbolt and can be controlled with your Alexa or Google smart voice assistant. Taking these personal considerations into account will help you find a smart lock that fits your needs.
Here are a few questions to consider:
The deadbolt on your existing door lock is the primary security feature that stops intruders from walking right in. Smart door locks still rely on the deadbolt, but some retrofit your existing deadbolt while others replace it entirely. Which would you prefer?
Smart door retrofit locks like the August and Sesame Smart Lock can be installed in minutes. They simply attach to your existing door lock and add smart options to unlock your door and view activity logs remotely. If you choose a smart door lock that also has a key option, you can likely continue using your existing key.
Other smart door locks like the Schlage Sense Bluetooth Deadbolt and the Yale Assure SL Touchscreen Deadbolt are designed to replace your existing door lock. These smart door locks take just a little longer to install (roughly 20 minutes) and will require a new key if there is a key option. Whole door lock replacements are more common and easier to find than the smart lock retrofit options above.
Smart door locks will work with or without a smart home, but you need to decide how smart you want your home to be before switching out your locks. Perhaps you are just beginning your journey to a smart home and foresee yourself adding smart devices in the future. If this is the case, be sure to choose a smart lock that's compatible with your preferred smart home hub or assistant. For example, if you have your eyes on a Google Home system, you'll want to choose a smart door lock that works with Google Home smart speakers.
Once you install your smart lock, you can give voice commands to your smart assistant. Being able to have Alexa unlock the front door when your friends arrive for dinner or lock it as you put your little ones down for the night can make life so much easier.
Depending on the smart door lock you choose, you might even be able to set up reminders that alert you if your door is unlocked at a time that it is typically locked. Some smart door locks will also lock automatically at a scheduled time. The options are endless!
Yes, all smart door locks require power to function, but some types require more than others. The three most popular are Bluetooth, Z-Wave, and WiFi.
Smart door locks powered by Bluetooth technology offer the most extended battery life and have a limited range. These smart locks require you to be about 300 feet or closer to unlock. They can use geofencing to unlock when you're within range automatically. These features can be incredibly convenient if you're juggling cranky kids or have your arms full of shopping bags.
Bluetooth door locks are excellent for homes with open floor plans, but if you have many walls that could block the signal, you might want to consider another type of door lock.
If you're not into the whole smart home trend but want to take advantage of smart locks, Bluetooth may be the best option for you. They don't require a hub to work. However, you can't manage these locks outside your home should you leave for work and forget to lock the door.
If you decide to buy a Bluetooth-powered smart door, you might consider the August Smart Lock, Friday Lock, or Kwikset Kevo.
Smart door locks powered by Z-Wave offer more connectivity options than Bluetooth door locks but require both a hub and WiFi. Should you choose a Z-Wave smart door lock, be sure to choose one that's compatible with your preferred hub. Popular options are Samsung SmartThings and Wink Hub.
To work correctly, you'll need to place your hub within 120 feet of the smart door lock. However, extending the range up to 600 feet with a compatible extender or additional Z-Wave smart lock is possible. Once connected, you can remotely control your door lock with your hub app.
Popular Z-Wave powered smart door lock options include the Schlage Camelot Touchscreen Deadbolt or Poly-Control's Danalock (Z-Wave).
Smart door locks powered by WiFi offer the most versatility but the shortest battery life.
You can control WiFi door locks from anywhere in the world with a WiFi connection. Meaning - you can lock your door while on vacation and let a delivery driver in when you're at work.
These smart door locks are the preferred choice of homeowners using multiple smart home devices, as compatible devices can all be connected and controlled simultaneously. For example, you might create a bedtime setting that locks your front door, turns the lights off, turns the heat down, and plays your favorite calming music, all with the spoken words, "Goodnight Google." If you plan to connect your smart door lock to other smart devices, be sure you choose compatible devices.
If you think a WiFi-powered smart door lock is for you, you'll want to take a closer look at the August Connect and Kwikset Kevo Plus. Some Bluetooth and Z-Wave smart locks also offer the ability to add WiFi connectivity.
One of the most popular features of smart door locks is opening a door without a key. This technology has become increasingly common in cars. Like in cars, smart door locks have options to unlock with a smartphone app, a passcode, a fob, or a fingerprint. Which sounds the most attractive to you?
Keyless entry means you'll never accidentally lock yourself out of your house again. It also means you can take a walk without having to carry your keys. Smart door locks are incredibly convenient if you ever hire home help. Imagine granting access to your housekeeper, dog walker, or babysitter without having to cut them a key. You can even pair your lock with a smart camera to see when a delivery driver arrives and ask them to place the package just inside the unlocked door. Keyless smart locks are also extremely popular with homeowners who rent out rooms or exterior dwellings on Airbnb. You'll never have to leave a key under the mat again!
Not ready to give up your key entirely? As we mentioned above, you can still use a standard key with some smart door locks.
Almost everyone carries a smartphone nowadays, which makes smartphone entry incredibly convenient. Depending on the smart door lock you choose, you can unlock your door by tapping the app, by knocking on your smartphone, or by merely having your smartphone within range of the door. The "Knock to Unlock" feature is integrated into Poly-Control's Danalock and the Sesame Lock, among others. Like the keyless options, you can also grant temporary access to guests, friends, and hired help at a moment's notice using your smartphone app.
Keyless or passcode locks make it possible to ditch your keys and unlock your door with a self-chosen alphanumeric code instead. Multiple codes can be programmed into many locks so that you can give different codes to each person. Unique codes offer added security by allowing you to view activity logs and receive instant notifications each time a code is used. For example, you might give each of your family members their code so you can see when each child gets home from school. Codes can also be scheduled to expire at a set time or be one-time-use.
Smart door lock key fobs work with Radio Frequency Identification (RFID) and an electromagnetic system to sense a fob buried deep in your purse or pocket. This technology makes it possible to go keyless and maintains the utmost security since the door can only be unlocked if the fob is within a certain distance.
You might consider a double authentication lock, like the Samsung Digital Door Lock, that requires both RFID and a passcode to unlock for added security.
Biometric locks are the most futuristic smart door lock option. These smart door locks feature a built-in touchscreen or scanner to read your fingerprint, eye, voice, or even your DNA before granting access to your home. Like the Samsung Fingerprint Digital Door Lock, most biometric locks will recognize multiple different fingerprints so everyone in your family can have access. You can even remotely remove access if, for example, your babysitter quits last minute. Many of these locks are also available with double authentication protection.
Unfortunately, there aren't many options for smart door locks in sliding glass doors. While the need is certainly there, sliding glass doors don't maintain a single design as front doors do. Smart door locks require a deadbolt to maintain the security of your home, which most sliding glass doors lack.
However, there are some workaround options.
Because smart door locks use a digital system, they are susceptible to hacking attempts. And, while smart door hacking isn't frequent, we recommend you take precautions to keep your family safe and secure.
How to Protect Your Smart Door Lock From Hackers:
Yes, keypad smart door locks can be very safe if set up correctly. Like any passcode, you must choose a strong code and change it often. Never use easy-to-crack passcodes like "1234," "abcde," your address, or your birthday. Since four-digit codes are commonly used, consider using five or more digits. It would help if you also planned to change your code regularly.
Most keypad door locks will allow you to change your code from the smartphone app to make it easier to manage. You can also use the app to delete codes. For added security, look for a keypad door lock that will block entry after a certain number of failed attempts and those with double authentication.
Most smart door lock batteries will last about a year. WiFi smart door locks have the shortest battery life, and Bluetooth smart door locks have the longest. Of course, battery life is also dependent on your use and the door itself. A door that closes and locks easily doesn't put extra strain on the lock, while a door has to be forced will. Batteries will also drain faster on doors that are used more frequently. To keep your smart door lock working effectively, be sure to check the battery life regularly.
If you're tired of constantly searching for your keys, it might be time to consider a smart door lock. Smart door locks will maintain the security of your home while providing all kinds of extra conveniences. Are you ready to make the switch?
