Why Upgrade to a Keyless Door Lock for Your Back Door?
Your back door is a common entry point, and a keyless lock removes the hassle of fumbling for keys, especially when your hands are full. These locks offer enhanced security features like auto-lock, access codes for guests, and remote monitoring, giving you peace of mind.
What to Check Before Buying
Door Compatibility. Measure your door's backset (2-3/8 or 2-3/4 inches) and cross bore (typically 2-1/8 inches). Most locks fit standard doors, but always verify.
Connectivity. Decide if you need built-in Wi-Fi or if you have a smart home hub (Z-Wave, Zigbee, Thread). Built-in Wi-Fi is simplest but may drain batteries faster.
Battery Life. Look for locks with 6+ months of battery life and low-battery alerts. Lithium batteries often last longer in cold weather.
Key Override. Always choose a lock with a physical key override for emergencies, such as a dead battery.
Smart Home Integration. Ensure the lock works with your existing ecosystem (Alexa, Google Home, Apple HomeKit) for voice control and routines.
Mistakes to Avoid
Skipping the Key Override. A lock without a physical key can leave you locked out if the battery dies. Always opt for a model with a key backup.
Ignoring Door Material. Metal doors may require specific installation kits. Check the manufacturer's compatibility guide before purchasing.
Forgetting About Guest Access. If you frequently have guests or service providers, choose a lock that allows you to create temporary or scheduled codes.
Overlooking Security Ratings. Look for locks with ANSI Grade 2 or 1 certification, which indicates higher security and durability.
