Which smart locks to avoid?

The fundamental of buying a smart lock is the same as those associated with traditional locks with keys. Don’t head over to an eCommerce website and pick up a $10 or $20 smart lock. 

We all know how safe these cheap locks are irrespective of smart or dumb locks.

The locks are meant to act as a deterrent for criminals. Whether it is a smart or non-smart lock, it is supposed to make breaking in difficult and time-consuming so that thief eventually gives up. A criminal who is determined will just make his way by kicking in the door or finding some other loophole.

Don’t buy those entry-level smart locks or deadbolts. The encryption and security features are a bare minimum.

Always remember, a smart lock is not another cool tech device you want to own. The enhanced security features and more control are the primary reasons smart locks are becoming popular.

The Psychological effect: Why smart locks are more secure?

Smart locks have a psychological edge over old locks. It gives an impression to the criminal that the house may be a smart home. It may be equipped with more smart security features not evident to the naked eye.

We always recommend adding a smart security spotlight camera and a smart video doorbell along with a smart lock. 

These become a big deterrent for criminals. Their minds will have a second thought about putting their safety at stake.

The same encryption technology or similar encryption method has already entered our daily lives. The biggest vote comes from our online banking system. 

How often do we hear about encryption failures or bank accounts being hacked? Most of the cases are of human negligence where they have been susceptible to phishing.

The smart locks are quite capable and secure. It is a human error that makes prone to breaches.

A human error includes using third-party apps or apps not authorized by the company. Have look at this 2016 video where a professor and students of the University of Michigan College of Engineering demonstrate how they hacked a smart lock.

But the reality is, it is a third-party app made by them through which hacked codes. So if a customer uses their app (an unknown third-party app), the security can be breached. 


Always use an authorized app and equipment.

The effort and expertise required to hack a smart lock are far more than the mechanical techniques in the normal dumb lock. Additionally, many smart locks have built in-alarm that fires whenever there is an attempt to tamper.

Final Thoughts
