How to Calibrate Eufy Smart Lock: A Complete Step-by-Step Guide

If you’ve recently installed a Eufy Smart Lock or noticed it’s not working as smoothly as it used to—maybe it’s jamming, not locking automatically, or the app says it’s “misaligned”—then it’s time to calibrate it. Calibration is a crucial maintenance step that ensures your smart lock operates reliably, securely, and efficiently. Whether you’re using a Eufy Smart Lock Pro, Eufy Smart Lock Bolt, or another model in the Eufy lineup, the calibration process is similar and can be done in just a few minutes using the EufySecurity app.

In this guide, we’ll walk you through everything you need to know about calibrating your Eufy Smart Lock. You’ll learn why calibration matters, how to prepare your door and lock, the exact steps to follow in the app, and what to do if things don’t go as planned. By the end, your lock should be perfectly aligned, responsive, and ready to keep your home secure.

Why Calibrating Your Eufy Smart Lock Matters

Before diving into the how-to, let’s talk about why calibration is so important. Think of your Eufy Smart Lock like a high-precision machine. It uses motors, sensors, and software to detect when your door is closed and then automatically engage the bolt. But if the lock isn’t properly aligned with the strike plate (the metal plate on the door frame that the bolt slides into), it can struggle to lock or unlock. This leads to frustration, battery drain, and even security risks if the lock fails to secure your door.

Calibration essentially “teaches” the lock how your door behaves. It measures the exact position of the bolt, the resistance it encounters, and the optimal timing for locking and unlocking. This ensures smooth operation, reduces wear on internal components, and improves battery life. Plus, many advanced features—like auto-lock after 30 seconds or voice control via Alexa or Google Assistant—depend on accurate calibration to work correctly.

Without calibration, you might experience:
– The lock not fully engaging the bolt
– The motor straining or making loud noises
– The app showing “Lock Jammed” or “Misaligned” errors
– Inconsistent auto-lock behavior
– Reduced battery life due to repeated attempts

Calibrating your Eufy Smart Lock resolves these issues and keeps your smart home running smoothly.

Before You Begin: Preparation and Checks

Before starting the calibration process, it’s important to make sure your door and lock are in good working condition. Skipping this step can lead to failed calibration or recurring problems. Here’s what you need to do:

1. Ensure the Door Closes Properly

Your door should close smoothly without sticking or requiring force. If the door is warped, sagging, or the frame is misaligned, the lock bolt may not line up with the strike plate. This will interfere with calibration.

– Close the door gently and check if it latches without resistance.
– Look for gaps between the door and frame—especially at the top and sides.
– If the door sticks, try adjusting the hinges or sanding down any rough spots.

2. Check the Strike Plate Alignment

The strike plate is the metal piece on the door frame that the lock bolt slides into. If it’s loose, misaligned, or installed incorrectly, calibration won’t work.

– Open the door and inspect the strike plate. It should be flush with the frame and securely screwed in.
– If the bolt doesn’t slide in easily, you may need to adjust the strike plate. Loosen the screws, reposition it slightly, and tighten again.
– For minor misalignments, you can use a file to widen the strike plate opening.

3. Tighten All Screws on the Lock

Over time, vibrations from locking and unlocking can loosen screws on the interior and exterior components of the lock.

– Use a screwdriver to check and tighten all visible screws on the lock faceplate, mounting plate, and interior unit.
– Don’t overtighten—just snug them up to prevent movement.

4. Ensure the Lock is Fully Charged or Powered

Eufy Smart Locks are battery-powered, and low battery can affect calibration.

– Check the battery level in the EufySecurity app. If it’s below 20%, replace the batteries with fresh ones.
– Use high-quality alkaline batteries (like Duracell or Energizer) for best performance.
– If your model supports USB-C emergency power, make sure the port is clean and accessible.

5. Update the EufySecurity App and Lock Firmware

Outdated software can cause compatibility issues during calibration.

– Open the EufySecurity app and go to the device list.
– Select your smart lock and check for firmware updates. If available, install them.
– Also, make sure your phone’s app is updated to the latest version from the App Store or Google Play.

6. Clear the Area Around the Door

Make sure there’s nothing blocking the door’s movement—like rugs, mats, or furniture. The door should open and close freely during calibration.

How to Calibrate Eufy Smart Lock: Step-by-Step Instructions

Now that your door and lock are ready, it’s time to calibrate. The process is done entirely through the EufySecurity app and takes about 5–10 minutes. Follow these steps carefully.

Step 1: Open the EufySecurity App

Launch the EufySecurity app on your smartphone. Make sure you’re logged into the account linked to your smart lock.

– If you haven’t set up the app yet, download it from the App Store (iOS) or Google Play (Android).
– Follow the initial setup to add your lock if it’s not already connected.

Step 2: Select Your Smart Lock

From the home screen, tap on your Eufy Smart Lock to open its control panel.

– You should see options like “Lock,” “Unlock,” “Auto-Lock,” and “Settings.”
– Look for a gear icon or “Settings” button—this is where calibration is located.

Step 3: Navigate to Calibration

In the settings menu, scroll down until you find the “Calibration” or “Lock Calibration” option.

– On some models, it may be under “Advanced Settings” or “Device Maintenance.”
– Tap on “Start Calibration” or “Begin Calibration.”

Step 4: Follow the On-Screen Prompts

The app will guide you through a series of steps. Pay close attention—each one is important.

– The app may ask you to close the door completely. Make sure it’s fully shut and latched.
– You might be prompted to lock and unlock the door manually using the app or the keypad (if your model has one).
– The lock will run a series of tests, moving the bolt in and out while measuring resistance and alignment.

Step 5: Allow the Lock to Complete the Process

During calibration, the lock will make several locking and unlocking movements. This may take 1–2 minutes.

– Do not interrupt the process. Avoid touching the lock or opening the door.
– The app will display progress messages like “Testing bolt movement” or “Measuring alignment.”
– Once complete, you’ll see a confirmation message: “Calibration Successful” or “Calibration Complete.”

Step 6: Test the Lock Manually

After calibration, test the lock to make sure everything works.

– Use the app to lock and unlock the door.
– Try the keypad (if applicable) or fingerprint scanner.
– Check that the auto-lock feature engages after the set time (e.g., 30 seconds).
– Listen for smooth, quiet operation—no grinding or straining.

Step 7: Re-enable Auto-Lock (If Disabled)

Some models disable auto-lock during calibration for safety. If yours does, re-enable it:

– Go to “Auto-Lock” in the app settings.
– Choose your preferred delay (e.g., 30 seconds, 1 minute).
– Toggle the feature back on.

Troubleshooting Common Calibration Issues

Even with careful preparation, calibration can sometimes fail. Here’s how to handle the most common problems.

Calibration Fails or Gets Stuck

If the app says “Calibration Failed” or the process stops midway:

– Wait a few minutes, then try again. Sometimes a temporary glitch causes the issue.
– Restart the EufySecurity app and your phone.
– Ensure the lock has sufficient battery power.
– If it keeps failing, check for physical obstructions or misalignment.

“Lock Jammed” Error After Calibration

This means the bolt is stuck or not retracting fully.

– Manually unlock the door using the key (if your model has a keyhole) or the app.
– Inspect the strike plate—make sure it’s not too tight or obstructed.
– Try calibrating again after adjusting the strike plate.

Auto-Lock Doesn’t Work

If the lock doesn’t auto-engage after calibration:

– Confirm auto-lock is enabled in the app.
– Check that the door is fully closed—auto-lock won’t trigger if the door is ajar.
– Ensure the lock detects the door is closed. Some models use a door sensor; if yours does, make sure it’s aligned.

App Says “Misaligned” or “Check Alignment”

This usually means the bolt and strike plate aren’t lining up.

– Open the door and visually inspect the alignment.
– Loosen the strike plate screws and adjust it slightly so the bolt slides in easily.
– Tighten the screws and try calibration again.

Battery Drains Quickly After Calibration

If the lock is working harder than usual, it may drain batteries faster.

– Check for excessive resistance during locking—this can strain the motor.
– Ensure the door closes smoothly and the strike plate isn’t too tight.
– Replace batteries with high-quality alkaline ones.

Tips for Maintaining Your Eufy Smart Lock

Calibration isn’t a one-time fix—it’s part of regular maintenance. Here are some tips to keep your lock in top shape:

Recalibrate After Moving or Adjusting the Door

If you’ve moved the door, replaced hinges, or adjusted the frame, recalibrate the lock. Even small changes can affect alignment.

Clean the Lock Regularly

Dust and debris can build up in the bolt mechanism.

– Use a soft cloth to wipe the exterior.
– Blow out the keyhole and bolt slot with compressed air.
– Avoid using water or harsh cleaners.

Lubricate the Bolt (If Needed)

If the bolt feels stiff, apply a small amount of graphite lubricant (not oil, which can attract dirt).

– Spray a tiny amount into the bolt slot.
– Work the lock in and out a few times to distribute it.
