The August Wi-Fi, (4th Generation) Smart Lock is our number 1 pick for the best smart lock to buy in Australia. Everything that you’ve grown to love with the original August Smart Lock is still available but with excellent improvements. One of which is its direct connectivity to your home wi-fi instead of installing through the August Connect Bridge.

The installation of the smart lock itself is just a breeze. This technology will upgrade your existing deadbolt lock into a cutting-edge smart lock. In fact, most of the Kwikset single cylinder deadbolts will work with the August Wi-Fi Smart Lock. Just to be sure, you can always check out the list of compatible deadbolt locks on the brand’s official website.

It has the DoorSense technology which can detect the current status of the door—whether or not the doors are left ajar if it’s closed, open, locked, or unlocked.

Another great thing about this is that you don’t have to necessarily throw away the original key. You can keep it and use it in instances where you don’t have access to your smartphone or smartwatch. In addition, you can install a keypad for keyless access without the use of a gadget.

You can even produce guest keys for family, friends, and trusted people so that you won’t have to hide spare keys somewhere on your porch. You’ll have full control and you can connect digital assistants, like Siri, Alexa, and Google to help open, lock, and keep tabs on your door’s activity feed.

Pros
  • DoorSense integration
  • Smart Home compatible
  • More ways to access the door
Cons
  • It may not be compatible with a 5 GHz wi-fi network

Lock Type: Deadbolt | Smart Home Compatibility: Google Home, Alexa | Alarm: None | Keypad: Optional | Batteries: 4 AA batteries

The August Smart Lock 3rd gen was considered as one of the best smart locks in 2019. It was just dethroned when its successor was released which is understandably logical. But just like Hollywood, you’ll never forget the original.

The August Smart Lock Pro is not limited to Wi-Fi connectivity. With the August Connect Bridge, you are able to connect to the locking device via BlueTooth and Z-Wave Plus. Unfortunately, this model doesn’t have the Apple HomeKit nor the Amazon Key support.

What made this a hit a few years back because it introduced a concept appealing to those who rent their homes. You only had to install the device on the existing deadbolt without having to scoop out the whole cylinder. When you move out, you can just simply remove the device without ruining the lock—keeping your landlord happy and your deposit safe.

If you want an August smart lock, but want to save a few buck then consider this over the newer model.

Pros
  • Easy BlueTooth connectivity
  • DoorSense integration
  • Easy to install
Cons
  • The separate Connect module may be a hassle to install

It has the DoorSense technology as well that uses a small magnet to detect if the bolt has slid into place to confirm the door is fully locked.

Instead of a rubber number pad, it makes use of a touchscreen that dims away after it locks and enters into Standby mode to conserve battery. When wanting to enter back into the house, you will just have to double-tap the screen to enable the digital number pad – very cool stuff indeed

To enable smart home features, you will have to buy the Yale Access Upgrade kit

Smart Locks: Buyer’s Guide

The best smart locks should offer you great versatility in terms of functions and security. But up to what degree? With all these great innovations, you might be feeling lost and confused as to what product will work great for you. To help you make the smart decision here is a comprehensive buyer’s guide explaining the factors that you should consider:

Lock type

Generally, there are two types of smart locks for the door: the deadbolt type and the door lever. As observed in this article, the deadbolt type is more common than the other one. Nonetheless, the lever-type smart lock is becoming more and more apparent in the market.

Choosing either one is more of a personal preference and what you can work with as easily as you can without having to bear new holes on your door.

Smart home and Wi-Fi connectivity

Not all smart locks have smart home and Wi-Fi connectivity. Others even just have a Bluetooth connection for you to be able to connect to your lock through the app. The best smart locks will offer wide-range connectivity to either of the Smart Home assistants, Alexa, Siri, or Google Assistant. And to be able to do so, it should be connected to Wi-Fi.

If your goal is to connect your whole house to centralized smart home connectivity, then you may want to look into the products that are compatible with your already existing smart home ecosystem. Most use Amazon’s Alexa while others opt for Google. Apple’s HomeKit, on the other hand, is becoming more and more visible in people’s houses.

So, what do you have at home? Then, pick out a product that has the same smart home compatibility.

The second point that’s worth emphasizing in this section is the availability of Wi-Fi connectivity in smart locks. New innovations have integrated a built-in Wi-Fi system into the products. However, it’s still a developing norm that only the best of the best smart locks will have like the August Smart Lock. Most of the products still need a Wi-Fi Connect Bridge to enable said connectivity. Some will include that added device in the package, while others will make you buy it separately. This is why you need to be very careful when ordering. You have to double-check if the bridge is included or not.

Smart lock interaction

Some products will have multiple ways to unlock the device. The most common is via an app and by typing a code on the lock’s keypad. Many have already integrated fingerprint readers, which is very high-tech.

The new set of smart locks with keypads offer great options such as generating temporary passcodes for your visiting friends, family members, and of course, for the service people you hired to do some work inside the house while you are away. They usually get timed codes that’ll expire after the date and time you set. This is to make sure they won’t have access to your door after they’ve served their purpose.

If this is something that’ll make you even more secure, then you might consider looking into the products that’ll offer this kind of feature. Meanwhile, there are products that’ll offer a mechanical key, which is great backup access, just in case you encounter machine failure with your smart device. This is very useful, especially when your device runs out of batteries.

Design

Smart locks usually carry a sleek design, style, and finish. What you will do for then is what will complement your home decor the best. Most will come in some sort of metal material, either brass, silver, and bronze. Others will throw in simple design variations to make the smart lock more appealing than the others and for it to stand out from the rest.

Budget

High-tech security can be a bit costly. But the perks that it can give you are priceless. Spending a few dollars could mean saving hundreds and thousands of dollars worth of furniture, appliances, and not to mention, jewelry. Also, our loved ones’ lives are obviously priceless, and ensuring their safety is one of our utmost priorities.

The best smart locks shouldn’t cost you a great deal. What you want to consider is if you’ll be able to save when opting for a product with a built-in Wi-Fi or will it be more expensive than buying one with a separate connect bridge device. There are also hidden gems that are offered at an affordable price but sports premium-like features. So be on the lookout for that.

Final Thoughts

Overall, installing the best smart locks in the market is a very wise decision. In the long run, most, if not all, houses will have smart locks. With how the tech trend is going, it wouldn’t take long for it to be a normal device you’ll see in houses.

There are a lot of products made available in the market right now. But all you need to focus on is what will benefit you and your house the most. If you have the need to check the locks from time to time while you’re at work, especially when you’re a parent, then get one that comes with an app, a smart home, and Wi-Fi connectivity.

Don’t be afraid to heighten the security in your house as what it saves is way more valuable than what the smart lock cost.
