Smart Lock Features to Consider

Access Mechanisms

Codes or Electronic Keys are the most common access mechanism on keyless door locks. To unlock the door, you need to enter the code using the keypad. More advanced models also allow for Biometrics, which are fingerprint scans. Every person has a different fingerprint that’s difficult to mimic. Now you might be thinking, how many fingerprints can you save? Well, you can save as many as the members you have in your family.

More advanced models come with voice commands, face recognition, and Fob. The Fob is a small object. It comes paired with the keyless door lock. Users can carry the Fob in their pocket. As soon as they approach their locked door, the Fob sends a signal to unlock it.

Security Grades & Deadbolts

If you are techy, you know what an IP rating is. It is a universally accepted certification that tells how durable a smartphone is against dust, water, dirt, and other small floating particles.

Just like the IP rating for smartphones, the ANSI/BHMA certification is a widely accepted indicator of how secure a keyless door lock is. ANSI stands for American National Standards Institute, and BHMA is short for Builders Hardware Manufacturers Association.

These certificates are awarded after running a set of different tests on the lock. Now as a customer, when you are on your way to buy a keyless door lock, look for the ones with a grade 1 or 2 ANSI/BHMA rating.

Smart Home Integrations & Protocols

Do you have a locker to store important papers and money? Keyless door locks use the same mechanism as those lockers. Your home security systems can connect with your keyless door lock and work together. Moreover, you can also integrate your keyless door locks with your home security cameras.

Thanks to IoT (Internet of Things), most keyless door locks are also compatible with other smart devices at home. After you integrate your keyless door lock with the lights, you can make them turn off automatically as soon as you leave for work in the morning. Similarly, as you come back in the afternoon, the lights will turn back on automatically as soon as you walk in.

Battery Power & Backup Options

Most keyless door locks rely on a battery for power. And just like any other device that runs on battery, users need to replace the batteries from time to time. If the battery is running low, the keyless door lock will communicate it to the user. Look out for the battery power indicator light. If the keyless door lock has a screen, look out for any text that hints at a low battery. It is advised that users don’t delay replacing the battery. Otherwise, they run the risk of locking themselves out.

To save battery power, keyless door locks come with different mechanisms. Wi-Fi requires a lot of battery power, so this is why most keyless door locks are Bluetooth Low Energy (BLE).

Auto-Lock & Auto-Unlock (Geo-Fencing)

Along with Wi-Fi compatibility, most models also come with Bluetooth. Using the Bluetooth ID, the keyless door lock can figure out when you are in or when you are walking towards it. It can then light up the keypad screen or the fingerprint scanner.

Moreover, most keyless door locks don’t even require you to insert your code. You can pair your smartphone with your keyless door lock. After that, as soon as these two devices are nearby, they can initiate a wireless protocol and start communicating. This connection is protected via cryptographic keys. After it authorizes access, the door will unlock. The entire process takes only seconds to complete.

Smartphone Apps & Remote Access

But almost all keyless door locks come with an App. Using the app, users can control their them from any place on earth. They can set a new security code, monitor who gets in and who gets out, receive alerts about tampering, and so on.

You must be wondering what happens if you lose your smartphone? Well, to fend off against unwanted people breaking into your home using your phone, you can immediately disable all the security keys.

Along with Apps, most keyless door locks are now also compatible with different wearable devices such as Apple Smart Watch, and other home assistant devices such as Apple HomeKit, and Alexa.

Should I Buy a Keyless Door Lock?

Convenience – No more keys!

Convenience is a competitive advantage that keyless door locks offer. Users get solid security without having to carry a key. With a keyless door lock, they get remote access as well as home security monitoring. Furthermore, they also get hands-free aces to their home.

Imagine coming back home with a newborn in your arms. How convenient would it be if the door unlocked as soon as you walked into your driveway? Imagine coming back home from a heavy shopping spree. How convenient would it be to unlock the door as soon as you walk closer to the door? And lastly, for those of you who do not like carrying a bulky keyring, keyless door locks are just for you.

Fine-grained Access Control

In general, users are all set with one security code. After they set the code, they should share the code with their family members. Afterwards, they no longer have to worry about who gets locked out. However, from time to time they might have their relatives visiting them. They might also want to rent one part of their home to temporary tenants. In such scenarios, they don’t need to share the master code with their guests. They can easily set a new code and let their guests use it while they are staying. Once visitors have left, users can remove that code from their keyless door lock and they are good to go.

Most keyless door locks come with multiple code support. Some let their users save 10 codes. On the other hand, some have the option of saving hundreds of codes.

Easy Installation

Keyless door locks are very easy to setup. Most homes come with them pre-installed. But if you don’t have one yet, don’t worry. Installing a keyless door lock is very straightforward. Take the old traditional key off and set up the keyless door lock. That’s how easy it is.

Just one thing, before making a purchase, make sure you are buying a keyless door lock that supports the kind of deadbolt you have at your home. They come with screws and bolts, so all you need is a screwdriver. Moreover, once the keyless door lock is in place, you can go ahead and set it up with your smartphone, which should not take more than 5 minutes.

Increased Security

In plain terms, keyless door locks don’t require a physical key as traditional locks do. They do come with a physical key for adverse situations, but they mainly rely on electronic codes, fingerprints, Fob, and voice commands.

Upgrading to a keyless door lock means users are one step ahead when it comes to outsmarting potential burglars. No one can open the lock unless they have the right electronic key. If someone uses power tools to break into your home, they will immediately trigger the alarm. Moreover, they will also get a text on your phone. Along with convenience, enhanced security is also a plus of using keyless door locks. If users think about smart homes, smart locks are needed.

Remote Access & Monitoring

Users can access their keyless door lock using their smartphone. Using the app, they can see who has gotten in and who has gotten out. If they have ma maid who comes to clean their house after they leave for their office, they can easily check when the maid entered their home. Along with entry time, users can also see what time he/she left.

Moreover, homeowners can assign a new electronic key/code to guests that they were not expecting. What will happen if the guests go straight to their home while they are still at the office? They can greet them with the comfort of their home even when they are not physically there. All they need to do is open their keyless door lock app and create a temporary code for their guests.

Tamper Alarms

Unlike traditional keys that have no response mechanism, keyless door locks have their way of informing users about failed attempts to access their home as well as tampering.

Remember, “burglars are criminals of opportunity.” They are tempted when seeing a window is open. On the flip side, noticing a keyless door lock works as a deterrent. The burglar knows that if he or she tampers the lock, it will set off an alarm. Moreover, if users integrate their keyless door lock with home security systems, upon detecting tampering, a whole bunch of things are initiated, from security cameras starting to record the burglar and sending it to the owner’s phone to sounding all the alarms.

Common Questions relating to Keyless Door Locks

What is a keyless door lock?

Keyless Door Locks have become an essential part of every Smart Home. It might take years before people start considering them as important as a kitchen stove or a heater. But with new technological breakthroughs, rather than being a question of “why”, it is a question of “when”.

Most models now emphasize on complementing the overall décor of users’ homes. But that doesn’t undermine their advanced features. People will find feature-packed keyless door locks at every hardware store.
On the low-end, keyless door locks come with a keypad. And on the other side of the spectrum, there are models that come with touchscreen and cameras for face recognition. With the ones that require a code, there are up to 250 codes that can be used.

How does a keyless door lock work?

Most Keyless Door Locks now come with an App. You can use the app to remotely lock or unlock your door. Moreover, some keyless door locks rely on Bluetooth to sense your location and lock/unlock depending on that data.

Like many of us, forgetting codes is a common scenario. Now if you have a keyless door lock, you don’t want to write down the code on a piece of paper only to lose it later to a burglar. So, what do you do? Well, even if you forget the code, you will not be locking yourself out of your home. Most keyless door locks come with backup keys that work as an alternative to the code.

How do I use a keyless door lock?

Currently, you will find keyless door locks that run on RFID, NFC, Z-Wave/Zigbee, Wi-Fi, and of course Bluetooth.

RFID is commonly used in hotels. These keyless door locks come with a card. To unlock the door, you need to place the card on the lock or swipe the card against the lock, just like you would do while making a payment with your Apple Pay card.

And lastly, the Z-Wave or Zigbee technology works with multiple smart devices. Using this technology, your keyless door lock forms a mesh network with other smart devices at your home and communicate with each other to figure out when you are leaving and when you are coming back. You can also daisy chain commands together so if the door unlocks and its the evening, then automatically turn on the lights.

Can my keyless door lock be hacked?

Just like any other electronic device, keyless door locks are also vulnerable to hacks.

First, let us look at the downside. In comparison to traditional keys, keyless door locks can be tampered with from a distance. The bad guys don’t even need to physically be present in front of your home. But on the flipside, keyless door locks are typically a higher security grade than older locks.

They can can alert you and even the police if they detect a hack. That’s the beauty of it. Just like they can be hacked from a distance, they can inform about the breach to a lot of parties in seconds.

If worried about security, it’s best to choose a keyless door lock that is only accessible on a local network and does not communicate with cloud servers.
