Remove the old lock: Before you even attempt to install your smart lock, you first need to take out the old lock.

There are usually two screws holding the lock in place, grab your screwdriver and take them out. Once that’s done, open the door so you can access the front side of the lock. At this point, you’ll notice that the key assembly has come loose, simply pull it off.

Put together the smart lock: It goes without saying that you need to take the smart lock out of its packaging. A typical model comes with an indoor attachment, an outdoor piece, and some batteries.

Best Smart Locks FAQs

Do I need an automatic unlock and locking feature?

With an auto-lock feature, your door unlocks automatically once you come home. It equally locks automatically once you’re out that door. As an extension of that, you really don’t need to fiddle with your phone or even punch in your access code. The auto-lock feature uses your phone’s location to know exactly when you’re out of the door. It does the same whenever you’re approaching your house too and, as such, unlocks on cue.

To execute this properly, it uses GPS, Bluetooth, and Geofences to accurately depict your location. In a nutshell, using the GPS on your phone, the smart lock is able to detect when you’ve left home. In the same way, once you enter the geofence near the smart lock, it begins to scan for your phone via Bluetooth. Once a Bluetooth connection has been established, your door simply unlocks.

An auto-lock feature is a really smart and convenient way for you to use a smart lock. For instance, if you live with family or friends who pretty much get home at the same time as you do. The tech is developed so that multiple actions cannot be performed at the same time. However, in the case that your phone gets stolen, an intruder can easily gain access into your home as opposed to when you have a smart lock with a keypad instead.

Is a remote-control feature necessary?

You may be wondering if you absolutely need to get a smart lock with a remote-control feature. Sure, a smart lock with a keypad works just fine, so, what’s the big deal? You see, while a remote-control feature might not be completely necessary, it sure does come with a lot of useful benefits that you’ll come to  appreciate, some of them are:

You can make sure your door is locked: A remote control feature on your smart lock allows you to lock your door no matter where you are. This is especially useful if you have kids who get back from school before you close from work. The remote feature gives you the peace of mind that comes with knowing that your kids are safe and secure inside your home.

Conveniently allow guests in your home: Let’s say you’ve taken a trip out of town but someone’s going to house-sit for you. While giving them your smart lock access code is an option, it may not always be the safest route to take. With a remote-control feature though, you can simply control the lock and the unlock mechanism using your phone. This way, you can let your house sitter in without sensitive information, like your keypad code.

Check on status of your locks: Another great thing about a remote-control feature is that it allows you to check on the status of your locks when you need to. Using the smart lock app downloaded on your smartphone, you can log in to check if you left your front door unlocked. In fact, a lot of smart locks with remote control features send you notifications when your door has been left unlocked. Armed with this information, you can easily lock it from whatever location you are.

Easy access control: You no longer have to worry about getting locked out of your house when you have a remote feature. Since your phone acts as the access control to your smart locks, all you need to do is tap a button on your screen and you’re in.

How important is it to have a backup key feature?

Picture this, you’re on your way home, you get to your front door and take out your phone from your pocket only to realize that your battery is dead. First things first, panic sets in seeing as no one else is coming home for the next few hours. So, it dawns on you that you’ve been locked out. This scenario is not unique, in fact, owners of traditional and smart locks can relate. But, can it be avoided?

While a remote-control smart lock is quite a cool addition to your smart home, you need to have alternative options. That’s where a backup key feature comes in. One great way to go about this is by opting for a  keypad feature. A lot of smart lock brands incorporate a keypad with their locks. Using this, you can set up a unique access code that offers you more than one way to open or close your door.

Having a smart lock that offers you both keypad and remote-control access is especially beneficial as it ensures that you enjoy the convenience that comes with operating your locks using your phone. But, you can also rest easy knowing that you have a backup plan if your smartphone becomes indisposed.

What do I need to know about battery life?

At this point, it’s important to note that smart locks run on batteries. So, you can’t expect them to run smoothly without a little pick me up, or changing once in a while. In a nutshell, your batteries will need to be replaced in order to have your locks working properly. That being said, there are different types of smart locks, and their battery life typically depends on whether they use Bluetooth, Wi-Fi, or Z-waves for connections.

Bluetooth: Bluetooth smart locks are the most common models on the market. For that reason, it’s no surprise that they are usually quite cheap and easy to install. Even more, when it comes to power, Bluetooth smart locks are as good as it gets. Obviously different brands of smart locks have different battery lives, but the average battery life for a smart lock that operates using a Bluetooth connection is about 12 to 24 months. Note that this depends on the lock and the frequency of use.

Wi-Fi: WiFi-enabled smart locks are well-known for being the most advanced type out there.  In fact, they happen to be loaded with tons of impressive features. In terms of price, although they are not as affordable as Bluetooth smart locks, they are reasonably priced considering their range of performance. Their batteries tend to last between 1 to 3 months and that can be quite the hassle.

Z-Waves: Z-wave smart locks combine the tech advancements of the Wi-Fi smart lock with the longevity of the Bluetooth smart locks. So, it’s obvious why they are the most expensive of the three and can be complicated to set up. However, with a Z-Wave smart lock you can connect to plenty of other smart devices in your home. Furthermore, these locks usually last between 12 to 18 months before needing a battery change.

How secure are smart locks?

One of the most common questions asked about smart locks is whether they are safe. People are often wary of the security which internet-connected devices offer. Seeing as their family’s safety, along with that of all their valuables are on the line, so it’s a very reasonable question.

If you’re thinking of getting a smart lock and wondering if it is safe, another question you might want to ask is, how safe are the traditional locks that you already use? If you think about it, standard deadbolt locks are not very secure. Home invaders and burglars probably learn how to pick locks in ‘Home Invasion 101’. Also, it doesn’t take a lot of skills or time to learn. So, now you know this, why not opt for a smart lock? Smart locks are incredibly superior and typically require a key code that would take ages to crack. Further, it could only possibly be cracked assuming the home invader is highly skilled as a hacker, which let’s be honest, is rarely ever the case. Even more, smart locks offer remote-control access that allows you to control your locks using your smartphone. So compared to traditional locks, it’s safe to say that smart locks are the more secure option.

What happens if I lose my smartphone?

So, you’ve lost your smartphone. Yup, the same smartphone that acts as the remote control for your smart locks. First, note that there’s no need to panic, you’re not locked out forever. But before we get into that, I would like to give some quick advice. When getting a smart lock, select one that has a backup key feature, like a keypad, so in the event that you lose your phone, you can still get into your house using a unique access code.

Now, let’s assume that you don’t have a lock with a backup key feature, what’s the way out? Most smart lock brands have websites you can log into using the email you registered your lock with. Once you’ve logged in, a verification code will be sent to your inbox and you can use that to regain access. As soon as you’ve been verified, search for ‘lost phone’ on the site. This stellar security feature allows you to log out of all the apps connected to the lock. All in all, the thief won’t be able to get into your home once that’s done.

Lastly, you’ll need to download the smart lock app on another smartphone. Once you log in that phone can be used for remote control.

Are all apps compatible with Android and iOS devices?

A lot of smart locks come with apps that you can download on your phone. Thanks to this handy feature, your phone can act as a remote control. To download the app, you’ll definitely need to go to the App Store if you own an iOS device or Google Play if you’re sporting an Android device. Most smart lock apps can be downloaded on devices that use either operating systems, however, the setup and the overall look of the app may be different on each operating system.

Will smart locks work for any door?

Before you actually purchase a smart lock, you need to make sure your door is compatible with a smart lock. The goal of smart locks is to ensure that your deadbolt automatically locks and unlocks, however not every door works properly. Test your door out because when you lock and unlock your deadbolt, it should typically be in a smooth motion. If you need to apply force or to push/pull your door before it locks, then your smart lock may not function correctly. Seeing as you won’t be there to push or pull the door, the mechanism will do it’s best and register the job as done.

You would also need to check if your lock can fully extend into the jamb, as your smart lock will always attempt to extend fully. The great thing is that both of these door related issues can be fixed. So, thoroughly check your doors out and fix whatever deadbolt and jamb problems before installing your smart lock.
