Top Security Tips for Choosing Smart Home Locks

October 3, 2024

Smart home locks offer great convenience-no more fumbling for keys. But before you jump in and install a smart lock as part of your home security system, have you thought about how secure it is? This is not just against break-ins, but also your data and how the lock manufacturer protects it from hackers. In this guide, we'll walk you through the top things to consider before choosing a smart lock, so you can have peace of mind knowing both your home and your personal information are safe.

What are the security risks of smart home locks?

Smart home locks are an essential component of a home automation system, but they also come with potential risks. Break-ins are still possible if the smart lock isn't properly protected. Some common risks include weak passwords, unsecured home Wi-Fi or Bluetooth connections, or outdated software that hackers can exploit.

Is there a security risk difference between a Bluetooth and Wi-Fi lock?

There is not a substantial difference in security. Both can protect you, but work differently. Bluetooth locks are safe because a user needs to have a digital key (smartphone or fob) that is recognized-but they can still be hacked! Wi-Fi locks let you control your door from anywhere, but are still open to attacks, especially if your home Wi-Fi isn't secure. This is where having a reliable internet service with an updated router and password can make a difference.

What are the different grades of smart locks?

American National Standards Institute (ANSI) and Builders Hardware Manufacturers Association (BHMA) are organizations that set standards for the quality and security of door hardware, including smart locks. Grade 1 is the highest, most secure and most durable. Grade 2 works for most homes, while Grade 3 offers the least security. Aim for at least Grade 2 when choosing a lock.

Are smart locks tested for hacking by manufacturers? Can they guarantee privacy and security?

Some companies test their locks to see if they can be hacked, but no company can fully guarantee security. However, strong encryption, regular updates and good data-management practices help reduce the risk.

Can I read the privacy policy of a lock before I buy it?

Yes! You can find the privacy policy on the manufacturer's website to learn how the company handles your data-like your passcodes, fingerprints and even who visits your home. It's important to make sure they aren't sharing your information without your consent and that they're keeping it secure.

What security policies should I look for when buying a smart lock?

Choose a smart lock that has:

• Strong encryption. AES-256 is the industry standard and ensures that even if someone gets your data, they can't read it without a unique key.
• Two-factor authentication, providing extra login steps for security.
• Regular software updates to fix bugs.
• Clear privacy policy on how data is collected and shared.
• Penetration testing, where the company tests if the lock can be hacked.
• Secure data storage on encrypted servers.
• Warranty or guarantee, in case of security issues

What does the smart lock company do with the data it collects? Where should it be stored?

Smart lock manufacturers sometimes share your data with third parties, like cloud storage providers that store your information, such as AWS or Google Cloud, or analytics companies that study how you use the lock. In some cases, they might even share data with advertisers, which can be a privacy concern. Some companies also work with security firms to test their locks for vulnerabilities. It's important to know who is handling your data and to make sure your information isn't being misused or shared without your consent. Their site should provide all of this information.

How do I check a manufacturers' security ratings?

Look for certifications from independent security organizations like the IoT Security Foundation. These groups test products for vulnerabilities to hackers. You can also check customer reviews and tech blogs for insights into a company's security reputation.

What are the security red flags to look for?

Be cautious of companies that aren't clear about their security practices, have poor customer reviews or don't regularly update their software to fix issues. If a company has had security problems before, it's probably best to avoid purchasing a lock from them.

Can I find out if a company has been sued? How?

This is a good way to track a company's reputation. You can check online by searching for lawsuits with the company's name. Websites like the U.S. Consumer Product Safety Commission or legal databases like PACER also track product safety and privacy lawsuits. If a company has been sued, find out how it was handled and the settlements they reached with customers. Then it's up to you to decide if you want to buy their product.

If my software is outdated, am I vulnerable to a security risk?

If your smart lock's software is outdated, hackers can easily break in. Like your phone or computer, smart home locks need regular updates to fix problems and improve security. These updates often include patches to close any gaps that hackers might use to gain access. If you skip them, you leave the door open for attacks. So, it's important to keep your software up to date to ensure your home stays safe.
