Best Smart Lock Brand to Consider

For your home security, you should always choose the best one, the best smart lock if you can afford it. But you also can get some smart locks which are not very costly and gives really good service or just as much as you needed. Around $250 you will get a nice smart lock.

Some people prefer just home security whereas some fancy about that. You get to choose the kind of lock you want. To have a  smart lock is always a better choice. Like voice activation, not every people want voice activation to unlock or lock their doors. For some people, it’s really annoying.

There is a lot of smart lock brand out in the market. I’m discussing here top five of them.

Yale Security

Yale security is one of the best for making smart locks. They already made beautifully designed smart locks, two of the most popular are Yale Assure Lock SL (YRD 256) and Nest X Yale Lock With Nest Connect. Both are very stylish in design, and solid strong lock. Users review about these two are by far is very positive.

The second one works with Nest secure and is very quiet, sharp-looking which combines with Yale reliability with Nest IoT home connectivity. The first one Yale Assure Lock SL has voice assisted programming and really beautifully designed. It is a striking keyless touchscreen deadbolt lock which can be controlled remotely.


Kwikset is one of the other best brand in the market which make the best smart locks. They already made Kwikset Kevo Touch-to-Open Smart Lock which is more responsive than it’s predecessor, but it is also a bit more expensive and lacks some of the features you get with the latest crop of connected door locks. But it has a responsive sleek design, can integrate with third-party devices and easy to install.

It’s remote management cost extra. It has no voice control. Also Fobs and additional eKeys cost extra. The Kwikset Kevo powered by Unikey looks like a normal lock and can be opened with a traditional key. It’s just an alternate feature. If you have a paired touchscreen phone with it on your pocket you can unlock it with that phone.


Though we guess that Samsung is not the type of company which makes smart locks but they do and it’s quite good.  Samsung already made Samsung digital SHS which has digital keypad, RFID card, Remote control and Mechanical key, the capacity of 20 fingerprints, Method optical verification time less than one second and 100 fingerprints max.

August Lock

August is the best brand in making smart locks. The Home kit enabled August Smart Lock keeps tracks of who is entering and leaving your house. It offers all the latest technologies including voice activation and geofencing. But it is pricey, requires an additional component to control lock remotely.

They also have made another popular smart lock named August Smart Lock Pro which is bit upgraded than previous one. It’s easy to install and supports Bluetooth, Wi-Fi and Z-wave. It comes with a door sensor and a Wi-Fi bridge. It works with Alexa, Google and Siri voice commands and it supports IFTTT. It is the most fully equipped smart lock.


Both the new August and Schlage are the best smart lock brands in the market now. Schlage made Schlage Sense Smart Deadbolt which is compatible with Apple’s HomeKit. That means it can be opened via Siri voice command from an iPhone or Apple watch. The Schlage also includes a keypad. It has audible tamper alarm, easy to install and program but it is expensive and it needs third-party controller for remote Z-wave access.

Conventional Lock VS Smart Lock

                 Conventional Lock                            Smart Lock
Conventional locks usually open with the turn of a key. Smart locks usually open with using smartphone apps or voice command.
It works as long as you have got an extra key Smart locks don’t work like that
Breaking a traditional lock is more difficult than hacking a smart lock. If you know how to use a smart lock app properly then hacking into this is not so easy.
Prices for traditional locks range from $20 to $100 Because smart lock has so many features and it makes your life really simple it is expensive.
If your friend wants in while you’re out then for a conventional lock’s case he/she has to have a key of your house lock. With smart lock you can access your lock while you’re away, you can simply unlock your door by using your smartphone while your friend is there to go in.
To break a conventional lock a thief has to be there in front of your house for quite a while which is not really secure for thief either. To break a smart lock, hackers can hack your smart lock from mile away.
Conventional locks have come a long way. No trusting issue in that. Adding smart to devices like watches, light bulbs, computer, TV is okay but to front door of house has some trusting issue especially if it’s a new brand smart lock. Some people want to avoid that.


Loadal FAQ


What to do if a smart door doesn’t work?

Answer: At first try to check the app of the smart lock. See if you have accessed the permission. Also sometimes it needs an update, so update it quite often. Maybe the issue is about low batteries, check to see if you can turn the latch to manually lock the door. If it locks smoothly, you may have an issue with either your user codes or the lock communication with the panel. Finally, if you see everything mentioned above is okay then reboot it, that should solve the problem.

Are fingerprint door locks safe?

Answer: “There is always a risk that a net-enabled lock will get bricked or hacked,” says MIT professor Stuart Madnick, “most likely due to actions(or carelessness) of the owner.” So I would say if you’re a good user your lock will not get hacked but remember every tech things are hackable cause hackers just want some lose end and they hacks through that, so use it wisely.

Can a smart lock be hacked?

Answer: Like I said everything in this world is hackable because there could be some loose ends. Where there is any lose ends if hackers are on to this for a long time then that could get hacked. You just have to learn to do things properly. You learn to operate your locks properly.

There should be no loose ends. Hire a pro to install your smart lock and learn to handle it properly. If something doesn’t work as you expected call to support.

What are the most secure locks?

Answer: Most break-ins are committed by criminals who come right through the front door, according to Department of Justice statistics. Even you are diligent about locking up, you need a good deadbolt to prevent thieves. Almost all the locks use steel in their cylinder and it can be drilled open. And there are some best locks which use hardened steel or brass and some of them reinforce the cylinder with some steel plates for which it’s really hard to drilled open.

As you can guess it’s still can be drilled open but it will take time to do that. For that maybe the thief will give up who knows. This is where smart locks are so useful. Smart locks set it’s alarm on, once it breaks a little or even someone enters into it’s perimeter so the thieves have literally no chance to break-in.

What to do if the fingerprint doesn’t work?

Answer: Depending on the brand of smart lock you using this could be different. I’m here writing the solution in general. There are actually two ways to reset fingerprints to lock or unlock the door. First way is, you have to completely reset the door lock and then remove the battery cover. There should be two batteries, remove both. Now tap on any number on keypad and locate the reset button.

At this point you have to refer to image on the right and press and hold the 2 reset buttons while re-inserting those two batteries. Wait for hearing the internal mechanism roll reset complete and then you have to release the two reset buttons. Another way is to reset a specific set of fingerprints.

You have to delete all fingerprints and also have to delete pin code. At this point press “0” and you should place admin finger on fingerprint scanner and press “2” and then press “1” again. To delete user fingerprints you have to press “0” and place the admin finger on fingerprint scanner and then press “2” and then press “2” again.

Now to delete guest fingerprints you should press “0” and place your admin fingerprint on scanner and press “2” and press “3” again.This way all the fingerprints will be erased except admin fingerprint and then you can use admin fingerprint. Preferably try to read manual/user guide whenever you’re stuck on something or contact to support if you can’t handle the situation.  

What to do if I forgot the password of the best smart door lock?

Answer: The answer of this question depends on the user using the brand of the smart lock. Depending on the brands the process can be different. Like for an august smart lock if you forgot your password simply go to the august smart lock app, go to sign in and press “forgot password”, then enter your phone number with country code. After submitting your phone number a few seconds later you will receive a 6-digit code from august in your message box.

Enter the code in the text field to continue. At this point, you will have to enter your correct email address so that they can send you a confirmation email with a security code. Get the security code from your email and put it on the august text field and then Voila! You can now change your password. All the other smart lock apps have pretty much same process of “forgot password” system.


I would say smart locks are not actually right for everyone. There’s lot of different people with lot of choices. Some people prefer old styles, some like smart ways, want their life journey keeping up to date. So it depends on someone’s choice whether he/she wants it or not.

I suggest you first check out the specifications of the smart locks, think about the advantages you would get using that as well as the disadvantages. If you think smart locks will make your life better and make your home safe you should give it a try.
