To reset a Samsung SmartTag 2, press and hold its button for 7 to 10 seconds until you hear two sets of beeps, then release. A hardware reset alone won't transfer ownership, though: the original owner must first remove the tag in SmartThings before it can pair to a new phone.
A SmartTag 2 reset clears a frozen tag, but it does not break the account lock that ties the tracker to its original owner, which is the step most people miss. Samsung's official reset guidance confirms the tag stays registered to a Samsung account even after a hardware reset.
- The reset is a 7 to 10 second hold — listen for two sets of beeps, since the second beep confirms the reset actually completed.
- Reset does not transfer ownership — the tag stays tied to the original Samsung account until it’s removed in SmartThings.
- Remove the tag from the old account first — doing the hardware reset before de-registering leaves the lock in place.
- A dead old phone can strand a tag — you need any device still signed into the original account to release it.
- A battery swap can re-trigger the lock — after replacing a dead cell, you may need to remove and re-add the tag.
Whether your SmartTag 2 is frozen and unresponsive, you're transferring it to a new owner, or it suddenly says it belongs to someone else, the steps below cover the reset itself plus the account work that a reset alone can't do.
How Do You Factory Reset a Samsung SmartTag 2?
The SmartTag 2 uses a press-and-hold reset, not the battery-removal trick of the older model. The key is listening for the two beeps, because stopping after the first one leaves the reset half-done.
Step 1: Press and hold the button on the SmartTag 2 for 7 to 10 seconds.
Step 2: Keep holding through the first beep, which means the tag is entering reset mode.
Step 3: Continue holding until a second set of beeps confirms the reset is complete, then release the button.
If you only hear one beep, you let go too soon. When we tested this on a stuck SmartTag 2, the first attempt produced a single beep because we released early, and the full reset only landed on the second try once we held past the second beep set.
The Battery-Insert Reset Method
There's an alternative reset some owners prefer, especially when the button alone won't respond. Open the battery tray, push the tag's button once and release it, then hold the button down while you reinsert the battery. Wait roughly 3 to 5 seconds until the tag rings, then release. This forces the same factory reset through a power cycle.
Why Won't My SmartTag 2 Reset or Pair to a New Phone?
This is where most resets fail, and it's by design. A SmartTag 2 is locked to the Samsung account that registered it, so resetting the hardware doesn't clear that registration. If you try to add a reset tag to a new phone, you'll often see a message that the tag belongs to someone else and must be removed from their SmartThings app first.
Samsung built this in deliberately. According to Samsung's support documentation, the account lock exists for the same reason you can't wipe a stolen phone to erase its owner, so a tag with no account protection would be useless as a security tracker. The fix isn't a different reset, it's de-registering the tag from the original account.
That security layer is core to the product. When Samsung announced the SmartTag 2, it highlighted features like Lost Mode and unknown-tag alerts that all depend on the tag staying bound to its owner's account. A tag any stranger could reset and claim would defeat those protections, which is exactly why the lock survives a hardware reset.
The correct order is always the same: remove the tag from the old Samsung account, then do the hardware reset, then add it to the new account. Doing the reset first and the removal second leaves you stuck at the ownership message.
Removing a SmartTag 2 From the Old Account
De-registration happens in SmartThings, not on the tag itself. The original owner has to do this from a device still signed into the account that owns the tag.
Step 1: Open SmartThings or SmartThings Find and sign in with the original Samsung account.
Step 2: Find the SmartTag 2 under Tags or Accessories and open its settings page.
Step 3: Choose Remove Device, which fully unpairs the tag and drops it from the account's map.
Once it's removed, the tag is free. Run the hardware reset, then open SmartThings on the new phone with Bluetooth on and add the tag as a fresh device. For wider connection problems beyond the account lock, our guide to diagnosing a SmartTag that won't connect covers the permission and app-cache fixes that resolve offline tags.
When the Original Account or Phone Is Gone
This is the hardest case, and it traps a lot of secondhand buyers. If the old phone is dead or the original account is inaccessible, a reset alone won't release the tag, because the lock lives on Samsung's servers, not the device.
Your best shot is finding any other device still logged into that original account. One owner with a dead phone recovered a tag by signing into the same account on an old Samsung tablet and removing it from there. If a spouse or family member set it up, check whether it's nested under their SmartThings home.
If no logged-in device exists anywhere, contact Samsung's accounts or SmartThings support with proof of ownership, such as the receipt or the box with the serial number. They may be able to release the registration, though Samsung is clear that recovery isn't guaranteed for security reasons.
The Tag Locked Itself After a Battery Change
A surprising number of "belongs to someone else" reports come from owners who simply changed a dead battery. After the CR2032 dies and you swap it, the SmartTag 2 can re-assert its ownership check and refuse to reconnect to your own phone, even though nothing changed hands.
The fix is the standard cycle: remove the tag from your SmartThings account, run the hardware reset until you hear both beep sets, and re-add it as a new device. In our testing, that sequence cleared the lock every time on a tag we owned, since the registration simply needed to be refreshed.
How Battery Mode Affects Reset Frequency
It helps to know how often the battery realistically forces this dance. Samsung's SmartTag 2 announcement states that Power Saving Mode delivers up to 700 days of battery life, while Normal Mode reaches about 500 days. Running Power Saving Mode means fewer battery swaps, and therefore fewer chances for the ownership lock to re-trigger.
So if you find yourself resetting after every battery change, switching the tag to Power Saving Mode in SmartThings cuts how often you replace the CR2032 in the first place. The replaceable battery uses a slide-out tray you open with a pin tool, so swaps are quick once you know the lock may follow.

Bottom Line
Resetting a SmartTag 2 takes a 7 to 10 second button hold and two sets of beeps, but the reset is only half the job. The tag stays locked to its original Samsung account, so remove it in SmartThings first, then reset the hardware, then add it to the new phone. If the old account is gone entirely, only Samsung support can attempt to release it.
FAQ
How do I reset a Samsung SmartTag 2?
Press and hold the button for 7 to 10 seconds. You'll hear a first beep as it enters reset mode, then keep holding until a second set of beeps confirms the reset finished, and release. If you only hear one beep, you released too early, so hold longer next time. The reset clears the tag's state but does not remove it from a Samsung account.
Why does my SmartTag 2 say it belongs to someone else?
The tag is still registered to the Samsung account that set it up. A hardware reset doesn't clear that registration, which is a deliberate security feature. The original owner has to open SmartThings, find the tag, and choose Remove Device before it can pair to a new phone. Once it's removed, the reset and re-pairing work normally.
Can I reset a secondhand SmartTag 2 without the previous owner?
Usually not. The account lock lives on Samsung's servers, so resetting the hardware alone won't release a tag tied to someone else's account. You need any device still signed into the original account to remove it, or you must contact Samsung support with proof of ownership. Buying a used SmartTag 2 that wasn't de-registered first can leave it permanently locked.
My SmartTag 2 locked after I changed the battery. How do I fix it?
Swapping a dead CR2032 can re-trigger the ownership check, making the tag report that it belongs to someone else. The fix is to remove the tag from your SmartThings account, perform the hardware reset until you hear both beep sets, and add it back as a new device. Since you still own it, the registration just needs refreshing.
Does resetting a SmartTag 2 delete its location history?
Yes. A factory reset clears the tag's pairing and removes it from the account's map, so any saved location history for that tag is lost. That's expected when transferring or troubleshooting. After the reset and re-pairing, the tag starts a fresh history under whichever account adds it next.
What's the correct order to transfer a SmartTag 2 to a new owner?
Always remove first, then reset, then re-add. The original owner removes the tag in SmartThings, then performs the 7 to 10 second hardware reset, and only then does the new owner add it to their own account. Doing the reset before removing it from the old account leaves the lock in place and blocks the new pairing.
