Best Smart Door Lock Reviews of 2019

Gone are the days where a sturdy lock consisted only of a simple mechanical device and a key. Now the future is upon us, and we have digital smart locks. These locks not only allow you to do away with keys, they also put access control in your hands anywhere you have access to wi-fi and you have a compatible smartphone, tablet, or personal assistant. That means no matter where you are, you can provide or revoke access to any visitor to your home or business. So even if you are traveling away from home, you can let people in or out of your house as needed.

What To Consider When Buying a Smart Door Lock

1. Fits Your Door

Before purchasing a smart door lock, check to see whether it will fit your door. This means checking that it will work with the dimensions of your door, the material from which your door is made, and the orientation of the hinges (on the right or left side). Also be aware that some smart door locks are sturdy enough that they can hold up to harsh weather, but others are really only suitable for indoor locations.

2. Compatible With Your Devices

You do not want to purchase a smart lock only to discover that you cannot control it with your device. Make sure that your smartphone, tablet, or personal assistant is compatible. Also check and see if there is any additional hardware you need to purchase, such as a proprietary hub. You do not want to be surprised by additional charges needed to get everything up and running. Some of the best smart locks do require you to buy additional equipment—you just need to factor in all the costs before you go shopping.

3. Stores All the Entry Codes You Need

Do you need just several door codes, or will you be giving out a lot of door codes to neighbors, employees, extended family, friends, or so on? Make a list of the people you might be giving door codes so that you can add them all up and figure out what kind of entry code capacity you will need. Shop for a smart lock which will provide you with that capacity. That way you can maximize control over your home or business security setup.

4. Location Detection and Other Advanced Features

One of the best things about smart locks is that some of them come with cool high-tech features which provide you with additional control over home or business access. For example, there are door locks which are able to detect your location. If you are approaching the door from outside, they may unlock automatically to let you in when you touch the lock. If you are indoors, they will keep the lock secure so that your family is safe.

Another advanced feature which some smart locks include is tracking. With this feature, you can check your lock’s history to see who has locked or unlocked it, who has accepted eKeys, and so on. You can even have notifications sent to you when certain users lock or unlock your door. This may be helpful for monitoring your home when you are on vacation, or checking to see if your kids are home from school.
