How to choose
When selecting a keypad smart lock under $100, prioritize these factors: Connectivity Type - WiFi locks offer direct remote access without additional hubs, while Bluetooth models require proximity but often consume less power. Access Methods - Look for multiple options like keypad, fingerprint, mobile app, and physical key backup. More methods provide better flexibility. Battery Life & Power - Check expected battery duration and low-power alerts. Most use AA batteries lasting 6-12 months. Ensure there's a physical key override or USB emergency power option. Installation - Verify compatibility with your door thickness and existing deadbolt. Most fit standard doors but measure beforehand. Security Standards - Seek BHMA/ANSI Grade 3 certification or higher for tested durability. User Reviews - Consider both rating and review count; a 4.6-star average from 50+ reviews often indicates reliable performance. Smart Home Integration - Confirm compatibility with Alexa, Google Assistant, or other platforms you use. Auto-Lock Feature - Adjustable automatic locking timers add security and convenience. Build Quality - Metal construction withstands weather and wear better than plastic components. Focus on features matching your primary use case—fingerprint readers excel for households, while WiFi connectivity benefits frequent travelers.

Frequently Asked Questions
Are keypad smart locks under $100 secure?
Yes, when properly installed and configured. Look for models with BHMA/ANSI Grade 3 certification, encrypted communication, and anti-peeping features that let you enter random digits before or after your real code. These locks often provide better security than traditional locks by eliminating key duplication risks and offering audit trails of all entries.
What happens if the battery dies?
Most keypad smart locks provide low-battery warnings weeks in advance. In case of complete power loss, reliable models include a physical key override or emergency USB-C/9V battery terminal to supply temporary power. It's wise to keep a physical key accessible or maintain spare batteries.
Can I install these locks myself?
Most keypad smart locks under $100 are designed for DIY installation with basic tools, typically requiring 10-30 minutes. They fit standard door preparations (2-1/8" bore, 2-3/8" or 2-3/4" backset). However, check door thickness compatibility (usually 1-3/8" to 2") and ensure your door is properly aligned for smooth operation.
What's the difference between WiFi and Bluetooth connectivity?
WiFi locks connect directly to your home network, enabling remote access from anywhere via smartphone apps and voice assistants without additional hardware. Bluetooth locks require proximity (typically within 30 feet) to connect to your phone, offering better battery life but limited range. Some locks offer both technologies for optimal flexibility.
