How to Change Eufy Tracker Battery: A Complete Step-by-Step Guide

If you own a Eufy tracker—whether it’s the Eufy SmartTrack Card, SmartTrack Tag, or another model—you know how convenient it is to keep track of your keys, wallet, backpack, or even your pet. But like all battery-powered devices, your Eufy tracker will eventually run out of juice. When that happens, knowing how to change Eufy tracker battery can save you time, money, and frustration.

This comprehensive guide will walk you through the entire process, from identifying when your battery is low to safely installing a new one. Whether you’re a tech newbie or a seasoned DIYer, we’ve made this guide simple, safe, and stress-free. By the end, you’ll be able to replace your Eufy tracker battery with confidence—no professional help needed.

Why Changing the Eufy Tracker Battery Matters

Your Eufy tracker relies on a small but powerful coin cell battery to function. This battery powers the Bluetooth connection that lets your phone locate the tracker when it’s out of sight. Over time, the battery drains—especially if you use the tracker frequently or leave it in high-alert mode.

Ignoring a dying battery can lead to unexpected disconnections. Imagine losing your keys and realizing your tracker died just when you needed it most. Regular battery checks and timely replacements ensure your tracker stays reliable. Plus, replacing the battery yourself is far cheaper than buying a new tracker every time the power runs low.

Signs Your Eufy Tracker Battery Needs Replacing

Before jumping into the replacement process, it’s important to confirm that the battery is actually the issue. Here are the most common signs that your Eufy tracker battery is running low:

• The tracker won’t connect to your phone: If your phone can’t detect the tracker via the Eufy Security app, a dead battery is often the culprit.
• Reduced range: The tracker may only work when it’s very close to your phone, even though it used to work from across the room.
• App notifications: The Eufy Security app may send you a low battery alert, especially if your tracker supports this feature.
• No LED light: Most Eufy trackers have a small LED that blinks when you press a button. If it doesn’t light up, the battery may be dead.
• Intermittent performance: The tracker works sometimes but not others, especially after being unused for a while.

If you notice any of these signs, it’s time to check the battery. Don’t wait until the tracker completely stops working—proactive replacement keeps your belongings secure.

What You’ll Need to Change the Eufy Tracker Battery

Before you begin, gather the right tools and materials. Having everything ready will make the process faster and reduce the risk of damaging your tracker.

Essential Tools and Supplies

• Replacement battery: Most Eufy trackers use a CR2032 3V lithium coin cell battery. Check your model’s manual to confirm. For example, the Eufy SmartTrack Card uses a CR2032, while some older models might use a CR2025.
• Small Phillips screwdriver: Needed to remove screws on models with a back panel. A #0 or #1 size usually works best.
• Plastic prying tool or spudger: Helps gently separate the tracker’s casing without scratching it. A guitar pick or old credit card can work in a pinch.
• Tweezers (optional): Useful for handling small screws or the battery itself.
• Clean, well-lit workspace: A flat surface with good lighting helps you see small parts clearly.
• Soft cloth or microfiber towel: Place this under the tracker to prevent scratches.

Safety Tips Before You Start

• Turn off the tracker: If your model has a power switch, make sure it’s off before opening.
• Work in a dry area: Avoid humid or wet environments to prevent moisture damage.
• Wash your hands: Oils from your skin can transfer to the battery and reduce its lifespan.
• Keep small parts organized: Use a small dish or magnetic mat to hold screws so they don’t get lost.

Step-by-Step Guide: How to Change Eufy Tracker Battery

Now that you’re prepared, let’s get into the actual process. The steps may vary slightly depending on your Eufy tracker model, but the general method remains the same. We’ll cover the most common designs, including the Eufy SmartTrack Card and SmartTrack Tag.

Step 1: Identify Your Eufy Tracker Model

Not all Eufy trackers are built the same. Some have removable back covers held by screws, while others use a snap-on design. Knowing your model helps you choose the right approach.

• Eufy SmartTrack Card: Slim, credit-card-sized tracker with a small screw on the back.
• Eufy SmartTrack Tag: Compact, keychain-style tracker with a seam around the edge that you pry open.
• Older Eufy models: May have different designs, so consult the user manual if available.

If you’re unsure, check the bottom or side of the tracker for a model number. You can also search “Eufy [model number] battery replacement” online for model-specific guides.

Step 2: Power Down the Tracker

Before opening the device, make sure it’s turned off. This prevents accidental button presses or electrical issues during the battery swap.

• If your tracker has a physical power button, press and hold it until the LED turns off.
• If there’s no power button, simply proceed—most Eufy trackers enter sleep mode when not in use.

Even if the battery is dead, it’s good practice to treat the device as if it’s still active until you’ve opened it.

Step 3: Open the Tracker Casing

This is the most delicate part of the process. Take your time to avoid cracking the plastic or damaging internal components.

For Models with a Screw (e.g., SmartTrack Card)

1. Place the tracker face-down on your soft cloth.
2. Locate the small screw on the back. It’s usually in the center or near one corner.
3. Use your Phillips screwdriver to carefully unscrew it. Turn counterclockwise.
4. Set the screw aside in your parts dish.
5. Gently lift the back cover. It should come off easily once the screw is removed.

For Snap-On Models (e.g., SmartTrack Tag)

1. Hold the tracker firmly in one hand.
2. Insert the edge of your plastic prying tool into the seam between the front and back halves.
3. Gently twist the tool to create a small gap. Work your way around the edge slowly.
4. Once the seal breaks, carefully separate the two halves. Don’t force it—apply even pressure.

Pro Tip: If the casing feels stuck, try warming it slightly with a hairdryer on low heat for 10–15 seconds. This softens the plastic and makes it easier to open.

Step 4: Remove the Old Battery

Once the casing is open, you’ll see the battery seated in a small compartment. Here’s how to remove it safely.

• Look for the battery—it’s a small, round, silver disc (usually labeled CR2032).
• Note the orientation: The positive side (with the “+” symbol) typically faces up.
• Use your fingernail, tweezers, or a small flat tool to gently pry the battery out of its slot.
• Avoid using metal tools directly on the battery terminals to prevent short circuits.

If the battery is stuck, don’t yank it. Wiggle it slightly from side to side until it loosens. Never use excessive force.

Step 5: Insert the New Battery

Now it’s time to install the fresh battery. Pay close attention to the orientation—installing it backward can damage the tracker.

1. Take your new CR2032 battery out of its packaging.
2. Check the positive (+) and negative (–) sides. The positive side is usually the one with the printed label.
3. Place the battery into the compartment with the positive side facing up (unless your model specifies otherwise).
4. Press it gently into place until it sits flat and secure.

Important: Double-check the orientation before closing the tracker. A reversed battery won’t power the device and could cause damage over time.

Step 6: Reassemble the Tracker

With the new battery in place, it’s time to put the tracker back together.

For Screw-On Models

1. Align the back cover with the front half.
2. Press them together until they snap or sit flush.
3. Reinsert the screw and tighten it gently with your screwdriver. Don’t overtighten—this can strip the screw or crack the plastic.

For Snap-On Models

1. Align the two halves carefully.
2. Press them together firmly, starting from one edge and working your way around.
3. Listen for a soft click or feel the pieces snap into place.

Make sure there are no gaps or misalignments. A poorly sealed tracker may let in dust or moisture, which can affect performance.

Step 7: Test the Tracker

The final step is to make sure everything works. Here’s how to test your newly powered Eufy tracker.

1. Press the button on the tracker. The LED should blink, indicating it’s powered on.
2. Open the Eufy Security app on your phone.
3. Go to the “Devices” tab and look for your tracker.
4. Tap on it to see if it connects and shows its location.
5. Try the “Find My Tracker” feature to confirm it’s working properly.

If the tracker doesn’t respond, double-check the battery orientation and ensure the casing is fully closed. Sometimes a loose connection can prevent it from powering on.

Troubleshooting Common Issues

Even with careful handling, you might run into a few hiccups. Here are some common problems and how to fix them.

The Tracker Won’t Turn On After Battery Replacement

• Check battery orientation: The most common cause is installing the battery backward. Open the tracker and verify the positive side is up.
• Ensure full contact: The battery must sit flat in its compartment. If it’s tilted or loose, it won’t make proper contact.
• Try a different battery: Sometimes new batteries are defective. Test with another CR2032 if available.
• Reset the tracker: Some models allow a reset by holding the button for 10–15 seconds. Check your manual for instructions.

The App Can’t Detect the Tracker

• Restart your phone: Bluetooth issues can sometimes be resolved with a quick reboot.
• Re-pair the tracker: Go to the Eufy app, remove the tracker from your devices, then add it again.
• Check Bluetooth range: Make sure you’re within 30–100 feet (depending on the model) and there are no major obstructions.

The Casing Won’t Close Properly

• Inspect for obstructions: Make sure no wires or components are pinched or out of place.
• Realign the halves: Sometimes the pieces shift during reassembly. Open and close them slowly and evenly.
• Avoid forcing it: If it doesn’t snap shut easily, something is misaligned. Don’t use excessive pressure.

Battery Drains Too Quickly

• Check usage habits: Frequent use of the “Find My Tracker” feature drains the battery faster.
• Update the app: Software updates can improve battery efficiency.
• Store properly: Keep the tracker in a cool, dry place when not in use. Extreme temperatures can affect battery life.

Tips to Extend Your Eufy Tracker Battery Life

Once your new battery is installed, you can take steps to make it last longer. Here are some practical tips:

• Use “Smart Alert” mode: This feature only activates the tracker when your phone is out of range, saving battery.
• Turn off unnecessary notifications: Constant alerts can drain power. Customize your notification settings in the app.
• Avoid extreme temperatures: Don’t leave your tracker in a hot car or freezing conditions. Batteries degrade faster in extreme heat or cold.
• Keep the firmware updated: Eufy regularly releases updates that improve performance and battery efficiency.
• Store with a charged battery: If you won’t use the tracker for a while, make sure the battery is at least 50% charged before storing.

When to Replace Your Eufy Tracker Entirely

While replacing the battery can extend your tracker’s life, there comes a point when upgrading is the better option. Consider replacing your Eufy tracker if:

• The casing is cracked or damaged beyond repair.
• The Bluetooth range has significantly decreased, even with a new battery.
• The tracker no longer pairs with the app, despite troubleshooting.
• You want newer features like longer battery life, improved range, or integration with smart home systems.

Eufy regularly releases updated models with better performance. If your tracker is more than 3–4 years old, it might be worth upgrading to a newer version.
