Door Access Codes

Need to provide delivery drivers one time access? Give your kids a specific codes, or for your visitor or Airbnb guest?

Smart locks typically provide more than one way to lock and unlock the door and provide access for others.

  1. Via an app
    All smart locks typically have this option where you download an app and then when you come into proximity of the lock can open and if authorized can control the door
  2. Built-in keypads
    Some smart locks come with physical buttons or touchscreen keypads so you can enter a code directly into the lock to open it from the exterior
  3. Add-on keypad
    Attached somewhere near your door these accessories talk to your lock directly so when an authorized code is added will open the lock.

Remote Locking

Check on the door's status and also unlock and lock your door from the comfort your bedroom, or even when you are away from the house on vacation.

What kind of connectivity your lock has will determine what range your lock is able to be controlled from.

  1. Bluetooth only:
    Control and access basically within ear shot of the door.
  2. Bluetooth + Wi-Fi hub:
    Many locks have an add-on Wi-fi device that connects to your router. This will let you access for your lock from anywhere you have Wi-Fi and throughout a larger home.
  3. Wi-Fi only:
    Control from a large home as well as remotely from work or anywhere you have a Wi-fi connection.
  4. Zigbee / Z-Wave:
    These rely on smart home hub that is connected to your home router. This hub is not included with the lock and will be an additional cost. Once connected to your router you will be able to control from anywhere with Wi-Fi access.

Featured Lock
The Schlage Encode lock is Wi-Fi enabled so you can connect and control it from anywhere without having to purchase an additional accessory.

Features Video

Video Camera / Doorbell Integration

Using HD security video cameras along with your new smart lock you can now get a complete awareness and control on what is happening:

Detect and record activity at your door.

Talk to your visitor using two-way audio.

Open the door remotely based on your interaction.

There are several ways smart locks get this capability.

  1. Built-in video camera in locks
    At the moment only a few locks have a built-in video camera.
  2. Separate camera
    Most locks on the market integrate with their own stand-alone video cameras using their app to manage both camera and lock.
  3. Separate camera from another company
    If the company does not produce their own video security camera systems they will often integrate with 3rd party providers like Ring or Arlo and show you the video stream via connecting the two services inside the app.

Featured Lock
The Gate Labs product is one of the few available that has a built-in video camera.

Voice
Smart Lock Voice Control

Smart hub integration and voice control

Tell Siri, Amazon Alexa, or the Google Assistant to lock or check the status of your door from your phone, smart watch or smart speaker.

If this is an important feature for you there are a few things for you to look out for:

Many smart hub companies will market their product as "Alexa enabled" but oftentimes will require an additional Wi-Fi hub to be purchased for this functionality to work.

This feature mostly comes down to the connectivity type of the smart lock you choose and if the company has made a voice assistant "skill". In general:

  1. Bluetooth only
    Can offer voice control but only in close range.
  2. Bluetooth with Wi-Fi add-on / Wi-Fi
    This should offer you voice control out of the box. Make sure to look for if the lock maker has an Alexa Skill or Google Assistant Action developed. (Note: We have added links for these on each specific lock page if they are available)
  3. Z-Wave and Zigbee
    Will work with voice controls using your smart home hub built in integrations or app. See here for how SmartThings interacts with Alexa for an example.

Featured Lock
The August Connect Pro with the additional Wi-Fi add-on will give you control from Siri, Alexa and Google Assistant.

Auto Lock & Geo-fencing

Smart locks can provide two different features for unlocking and locking when you arrive and leave.

  1. Hands Free Unlock
    Juggle more grocery bags. Many locks give you a touch or proximity unlock feature as long as you have the app running on the background of the phone and have access.
  2. Auto-lock when leaving
    Peace of mind. Almost all smart locks come with an auto-locking feature that can be time based to lock behind you as you leave. The typical default time for most lock is 30 seconds but can usually be adjusted in the settings.

Choice Icon

QUESTION #1

Rent or Own?

Do you live in a home or apartment that you own, renting, or are renting out on a vacation rental service?

Smart Home Own

I Own:

You should not have any issues here and should be able to use any smart lock that fits your particular door.

Continue to the door type section below to find a lock that fits.

Smart Lock Rental

I Rent:

In this case you need to look at some very particular locks that will keep your existing key, and not modify the outside appearance of your door and locks.

airbnb smart lock

I run a vacation rental:

If you need a smart lock for your vacation property there are options that allow you to automatically create specific access codes for each guests and be alerted after they successful check-in.

QUESTION #2

Keep Existing Keys or Replace?

Are keeping your current keys important

The majority of the smart door locks on the market are going to provide you with a new set of keys with your purchase.

That being said there are a few options where the locking mechanism is placed on top of your existing deadbolt lock or only the interior section of your deadbolt is replaced letting you keep your current keys.

These locks have an additional positive security benefit in it doesn't announce to anyone walking by that you have a smart lock installed as your lock looks the same from the exterior.

QUESTION #3

What door are you installing the lock on?

Smart Lock Access Door

Most Common

  • Front/Back Door

There are a number of internal smart door locks that should work for you.

Outdoor Smart Gate Icon

Outdoor Gate

Need some additional control and security for a side outdoor access or driveway gates?

QUESTION #4

Access Door: What type of door do you have?

OK, for your front or side access doors? Do you have a deadbolt and a handle hole, just a deadbolt, or is this for a sliding door?

Smart Lock Door Types

Mortise Style Locks

I have a longer/larger locking mechanism.

Sliding Smart Lock

Sliding Smart Door Lock

QUESTION #5

How important is cost when making a smart lock purchase?

The average price of a smart lock is a little higher than a standard door lock. For a budget lock expect to pay between $100 and $150 and for more features expect the price to go into the $200-$400 range.

Something to look out for is some of the lower base models will say they offer some features like Alexa support and remote locking but neglect to explain that it only works with the purchase of an additional Wi-fi bridge device (typically an additional $50-75 dollars)

Not a primary concern
I am looking for only the highest grade of finishes to match my front door style.

Important, but not critical
Budget conscience, but also want to make sure you get a high-quality lock? In this case, we recommended using our door type section to get the best match for you.

    Overview

    With Bluetooth already enabled on your smartphone, Bluetooth locks seem like an obvious choice to monitor and control your lock from.

    The downsides compared to other connectivity options is sometimes a reduced range and the fact that you can't control them past Bluetooth range without an additional Wi-Fi add-on that connects to a Wireless network.

    Good for: If you are living in an apartment or don't need remote control and access monitoring.
