The pros and cons of smart locks - the right one is the best

November 22, 2022

The global smart lock market size is predicted to hit USD 8.13 billion by 2030 and is anticipated to register a CAGR of 19.5% from 2022 to 2030, based on a recent report by Grand View Research, Inc. 

It means that having smart locks will become popular. So do you need to keep up? Here are our views on the pros and cons of smart locks for your reference.


Pros Of Having A Smart Lock

Ease Of Entry

With a smart lock, you don't have to fumble for the key or wiggle it around in the lock to get it to open.


If you’re expecting guests or a house sitter to come by while you’re away from home, you can input special codes for each person or group, along with an expiration time for each code. Also, if you’re worried that someone with a key (like a former property owner) may try to enter your home, you can just change the code, saving you the hassle and cost of changing the lock.

Peace Of Mind

Another benefit of using codes is that you can track who comes in and out, so you know if and when your children arrive home. In addition, with many smart locks, you can see if a door is locked or unlocked from your phone, so you can double-check its status from anywhere in the world.

Protection From Lock Picking

Traditional locks may be subject to lock picking or lock bumping—methods that thieves can employ to try to open locks without the original key. Some smart locks don’t have a key slot, thereby removing the risk of this kind of break-in. That doesn’t, however, necessarily make smart locks more secure. (More about this below.)

Connectivity With The Rest of Your Home

If you have other smart home devices, you might be able to interconnect them - for example, your smart lights turn on when you unlock the door.


Cons Of Having A Smart Lock

Reliance On Phones And Networks

Smart locks communicate with your phone, usually via Bluetooth or Wi-Fi. If your phone is stolen, you lose it or it dies, you could get locked out if you don’t have a backup plan (like logging in to your account on another device). Also, if a power outage shuts off the Wi-Fi, you wouldn’t be able to use features (like remote unlocking) that rely on a Wi-Fi connection.

Potential For Hacking

While some smart locks eliminate the threat of lock picking, they can be subject to hacking in an attempt to override the entry code for unlocking. On the bright side, the system may notify you (and the police) if an unauthorized user enters the system.


Unlike old-style locks, smart locks are battery-powered systems and the batteries may run out. You must be aware of this and replenish before it runs out of power.


Smart locks cost more than standard lock-and-key systems, and some locks may also require a professional to install the lock and sync it to your Bluetooth and Wi-Fi. If there is a breakdown, its repair costs may also be high.


Are the pros enough to outweigh the cons? It's up to you, the right fit is the best.
