Skipping the Door Compatibility Check
Purchasing a lock before confirming it will work with your existing door hardware is one of the most frequent smart lock buying mistakes. Smart locks are designed to replace or integrate with a standard deadbolt, but door thickness, backset measurements, and bore hole sizes vary. Older doors or custom installations common in many LA homes often fall outside the standard range that most off-the-shelf locks are built for.
Before purchasing, check these measurements against the lock’s listed specifications:
- Door thickness
- Backset distance from the edge of the door to the center of the bore hole
- Bore hole diameter
If your door has a non-standard configuration, a professional assessment will save you from returning the lock or forcing hardware that does not fit. Our smart lock installation service includes a hardware check so you know your door is a match before anything is mounted.
Choosing Connectivity Without Thinking About Your Setup
Smart locks connect through Bluetooth, Wi-Fi, Z-Wave, or Zigbee, and each has different range, battery, and hub requirements. Bluetooth locks are simple and battery-friendly but only work when you are nearby. Wi-Fi locks let you control access from anywhere but draw more power and depend on a stable network. Z-Wave and Zigbee locks require a compatible smart home hub, which is an additional piece of hardware many buyers do not realize they need.
If you already use a platform like Google Home, Amazon Alexa, or Apple HomeKit, confirm the lock is compatible before purchasing. Picking a lock whose connectivity does not match your existing setup is a common mistake that leads to features falling short of expectations.
Overlooking Battery Life and Backup Access
Some smart locks drain batteries far faster than others, particularly Wi-Fi-connected models under heavy use. Many buyers focus on features and finish without checking average battery life in the product specs, which leads to unexpected lockouts at inconvenient times.
When evaluating a model, look for:
- A low-battery alert through the app
- A physical key backup option on the exterior
- A clear emergency entry plan if you go fully keyless
A keyway on the exterior is not a step backward in security. It is a practical safeguard. Our lockout service is available around the clock, but building in a backup at the hardware level is always the smarter starting point.
Ignoring the Security Rating of the Lock Itself
A touchscreen keypad and an app do not automatically make a lock more secure than a well-built traditional deadbolt. Some smart locks on the market use thin housings, basic cylinders, and minimal anti-pick or anti-drill features. The American National Standards Institute grades residential deadbolts from Grade 1, the highest and designed for commercial use, down to Grade 3. Many budget-friendly smart locks carry only a Grade 3 rating, which offers less resistance to forced entry than a quality Grade 1 deadbolt.
Look for at least a Grade 2 ANSI/BHMA rating, and ideally Grade 1 if security is your primary concern. Brands like Schlage and Yale manufacture smart locks with strong physical ratings built into their product lines. The residential locksmith team at West Coast Locksmith regularly helps homeowners across Los Angeles find the right balance between smart functionality and solid hardware ratings.
Underestimating What Professional Installation Adds
Smart locks are marketed as DIY-friendly, and many straightforward installations on standard doors do go smoothly. But installation mistakes are common: misaligned strike plates, improper deadbolt throw alignment, or incomplete app configuration can leave a lock looking installed while not working correctly. A lock that binds or does not fully extend its bolt is a security vulnerability, not just a nuisance.
Professional installation ensures the hardware is set correctly, the door and frame are aligned, and every function is fully tested before we leave. You also get a walkthrough of the app, access sharing, and any features specific to your model. If you are considering rekeying other locks or adding a new lock to a secondary door, bundling the work into one visit is an efficient way to address your home security all at once.
Making an Informed Smart Lock Purchase
Avoiding smart lock buying mistakes comes down to doing the homework before you buy. Confirm door compatibility, match connectivity to your actual setup, check battery life and backup options, evaluate the physical security rating, and consider whether professional installation makes sense for your situation. A well-chosen, correctly installed smart lock is a genuinely useful upgrade for any home.
