One of the biggest complaints of smart locks is the fact that they can be hacked into. There was even a study that was conducted in the past that showed over 70 percent of them could be hacked. This is not an issue with standard locks. Of course, they can also be picked. But, you can play a role in limiting the risk of being hacked. Firstly, ensure that your network (if you are using your home network) is secured with top-of-the-line security. Install firewalls and change your default password.
