Best Smart Lock Under 100 Review
How to Choose the Right Smart Lock Under $100
Choosing a smart lock can significantly enhance your home security and convenience. However, with many options available, especially under $100, it’s crucial to understand which features matter most to your needs. Here’s a breakdown of key factors to consider:
Unlocking Methods & Convenience
The core benefit of a smart lock is moving away from physical keys. Consider the unlocking methods offered. Fingerprint recognition offers quick, keyless entry, and is very convenient, often with recognition speeds under 0.5 seconds in higher-end models. Keypad entry provides a secure alternative, especially for family members or trusted guests, and allows for temporary codes. Smartphone app control via Bluetooth or Wi-Fi adds remote access and monitoring capabilities. The more methods offered, the more flexible the lock is, but also potentially the more complex it might be to set up and use. Think about your daily routine and which method would be the most practical for you and your household.
Connectivity: Wi-Fi vs. Bluetooth
This is a major differentiator. Bluetooth locks connect directly to your smartphone, offering control within a limited range. They are generally cheaper but require you to be physically near the door to unlock or manage access. Wi-Fi locks, on the other hand, connect directly to your home network, enabling remote access from anywhere with an internet connection. This is beneficial for checking lock status, granting access to visitors while away, or receiving real-time notifications. While generally more expensive, the convenience and added security of Wi-Fi connectivity are often worth the extra cost – especially if you have a vacation home or frequently travel.
Security Features & Durability
Don’t compromise on security to save money. Look for locks with BHMA Grade 3 certification – this indicates the lock has met specific security standards. Features like auto-lock, which automatically secures the door after a set time, add an extra layer of protection. Anti-peeping PIN code protection (where entering random digits before your code masks it from onlookers) is a valuable feature. Consider the lock’s build material; aluminum alloy construction offers good durability and resistance to forced entry. IP ratings (like IP54 or IP55) indicate resistance to dust and water, crucial for outdoor use.
Battery Life & Backup Options
Smart locks rely on batteries, so consider the estimated battery life and the type of batteries required. Longer battery life (6 months or more) minimizes maintenance. Look for locks with a low-battery warning to prevent unexpected lockouts. A USB Type-C emergency power port is a valuable backup, allowing you to temporarily power the lock with a portable charger if the batteries die.
Installation & Compatibility
Most smart locks are designed for DIY installation, but some may require more technical skill. Check the door thickness compatibility and ensure the lock will fit your existing deadbolt. Consider if the lock is compatible with your smart home ecosystem (Alexa, Google Assistant) if you plan to integrate it with other devices.

Testing & Data Analysis: Finding the Best Smart Lock Under $100
Our recommendations for the best smart lock under $100 aren’t based on subjective impressions, but rigorous data analysis. We prioritize evaluating options based on publicly available specifications, independent security assessments (like BHMA Grade ratings), and extensive user reviews from verified purchasers across multiple e-commerce platforms (Amazon, Best Buy, etc.).

FAQs
What is BHMA Grade 3 certification, and why is it important for a smart lock?
BHMA Grade 3 certification indicates that the smart lock has met specific security standards set by the Builders Hardware Manufacturers Association. It means the lock has been tested for durability, strength, and resistance to forced entry, providing a baseline level of security for your home.
What’s the difference between Bluetooth and Wi-Fi smart locks, and which should I choose?
Bluetooth locks connect directly to your smartphone and require you to be within a limited range to operate. Wi-Fi locks connect to your home internet network, allowing remote access and control from anywhere. Choose Wi-Fi for remote access and features like real-time notifications; Bluetooth is suitable if you only need keyless entry when you’re close to the door and want to save money.
How long do smart lock batteries typically last, and what happens if they die?
Battery life varies by model, but most smart locks last between 6 to 12 months. Many locks have low-battery warnings to alert you before they die. Most also include a backup power option, such as a USB port, to temporarily power the lock and allow you to unlock the door manually.
Are these smart locks difficult to install?
Most smart locks under $100 are designed for DIY installation and should take around 30 minutes. However, ensure the lock is compatible with your door’s thickness and existing deadbolt. Some locks may require basic tools like a screwdriver.
The Bottom Line
Ultimately, finding the best smart lock under $100 involves balancing your security needs with desired convenience features. While top-tier models boast extensive functionalities, several affordable options deliver reliable performance and enhanced security over traditional locks. Carefully consider your priorities – Wi-Fi connectivity, fingerprint recognition, or simple keypad access – to make an informed decision.
Investing in a smart lock, even at this price point, offers a significant upgrade to your home’s security and provides peace of mind. Don’t compromise on essential features like BHMA certification and auto-lock functionality. With a little research, you can find a smart lock that fits your budget and seamlessly integrates into your modern lifestyle.
