Quick Answer
Okay, so here's the quick version. Your smart lock is eating batteries, and it's driving you nuts. Nine times out of ten, it’s either you're using cheap batteries, your Wi-Fi signal is weak, or—and this is the big one—your door is misaligned. That misalignment makes the motor work way too hard. First thing to do: toss the old batteries and put in a fresh set of brand-name Lithiums or Alkalines—whatever the manufacturer says. Cost you maybe $10-20. Then check the door. If that doesn't solve it, we'll dig deeper.
Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Replace all current batteries with a fresh set of high-quality, manufacturer-recommended batteries.
Step 2
Test the deadbolt's operation with the door open, then closed, to check for signs of rubbing or binding (misalignment).
Step 3
Check the smart lock's app for Wi-Fi or Bluetooth signal strength readings.
Step 4
Use the app to check for and install any available firmware updates.
Step 5
Inspect the strike plate on the door frame for scratches or wear marks indicating a poor fit.
Step 6
Monitor the battery life over several weeks after performing the above steps to see if the issue is resolved.

When to Call a Professional Locksmith
- You are locked out of your house and do not have the backup physical key.
- A fresh set of high-quality batteries drains completely in just a few days or weeks, suggesting a hardware fault.
- The door or frame is significantly warped and requires more than a simple strike plate adjustment.
- After trying all the basic troubleshooting steps, the lock continues to malfunction.
- You are not comfortable using tools to adjust your door's alignment and want it done correctly.
Prevention Tips
- Use only high-quality alkaline (Duracell/Energizer) or lithium batteries as specified by the manufacturer.
- Replace all batteries at the same time; never mix old and new batteries.
- Proactively change batteries every 6-12 months, setting a calendar reminder.
- Keep a backup physical key in a secure location outside your home, like a car or with a neighbor.
- Regularly check that the deadbolt operates smoothly without friction when the door is closed.
- Ensure the smart lock's firmware is always kept up-to-date through its mobile app.
- If the lock's location has a weak signal, consider adding a Wi-Fi extender to reduce power consumption.
