A Trezor factory reset sounds scary, and done carelessly it can be. But in most situations it’s a safe, routine step, as long as you understand one thing first: a factory reset wipes the device, not your coins. Your crypto lives on the blockchain, and your Trezor is only the key that signs for it. With your recovery seed in hand, you can wipe your Trezor and restore full access afterwards.
This guide explains exactly what a Trezor factory reset does, when you should do one, how to wipe every model (including how to reset a Trezor Safe 5), and how to restore your wallet cleanly once the device is blank.
What Does a Trezor Factory Reset Do?
A factory reset, also called wiping the device, erases everything stored locally on your Trezor: the wallet, the PIN, and any device settings. After a reset, the Trezor is blank, exactly as it was out of the box.
What a factory reset does not touch is your money. Your funds never sit on the device in the first place. They’re recorded on the blockchain, and the Trezor simply stores the keys that unlock them. Wiping the device removes those local keys, but they can be regenerated at any time from your recovery seed. That’s the whole point of the seed: it is the master backup of your wallet.
This also means the reset comes with one hard rule, which deserves its own section.
Before You Factory Reset: One Non-Negotiable Rule
Only factory reset your Trezor if you have your complete recovery seed, and your passphrase too if you set one.
A wipe with a valid seed is completely recoverable. A wipe without one is permanent. There is no undo, no backdoor, and no support team that can bring the wallet back, not even Trezor. So before you wipe anything:
- Find your recovery seed backup (the 12, 20, or 24 words you wrote down at setup) and confirm it’s complete and readable.
- If you used a passphrase, make sure you know it exactly, because your seed alone will only open an empty hidden wallet without it.
- If you’re unsure whether your seed is correct, verify it first with the Check backup feature in Trezor Suite, before you wipe.
If you cannot find your seed, do not reset the device yet. A working device is still access to your funds, so move the funds to a new wallet first, or speak to a recovery specialist.
When Should You Factory Reset a Trezor?
A factory reset is the right move in a handful of situations:
- You forgot your PIN and need to wipe and restore from your seed.
- You’re selling, gifting, or recycling the device and must erase your wallet from it.
- You suspect the device was tampered with or exposed, and you want a clean start (ideally with a brand-new seed).
- You’re troubleshooting a device that’s stuck, glitching, or not syncing, and a clean reset plus restore is the fix.
- You simply want to start fresh with a new wallet.
If your only problem is a forgotten PIN, our dedicated guide on a forgotten Trezor PIN walks through the whole flow in detail.
How to Factory Reset a Trezor Using Trezor Suite
If you still know your PIN and can unlock the device, the cleanest way to reset is through Trezor Suite. The steps are the same for the Trezor Model T, Safe 3, Safe 5, and Safe 7.
- Connect your Trezor and unlock it by entering your PIN.
- In Trezor Suite, click the gear icon in the top-right corner to open Settings.
- Open the Device tab.
- Scroll down to the “Danger Area” and select “Wipe device.”
- Confirm that you understand all data will be deleted and that you have a safe offline copy of your backup.
- Confirm the wipe on the device itself (tap to continue, then hold to confirm).
Once complete, the Trezor restarts blank, ready for you to set up a new wallet or recover your existing one. Trezor documents this flow per model, for example the official guide on how to wipe a Trezor Safe 5.
How to Reset a Trezor Safe 5 Specifically
The Trezor Safe 5 follows the same path, using its touchscreen for the final confirmation. Unlock the Safe 5 with your PIN, open Settings via the gear icon, go to the Device tab, scroll to the Danger Area, and tap “Wipe device.” Then confirm directly on the Safe 5’s screen by tapping to continue and holding to confirm. The device wipes and restarts ready for a fresh setup or a restore from your seed.
How to Factory Reset a Trezor When You Forgot Your PIN
If you can’t unlock the device because you’ve forgotten the PIN, you can’t use the normal Suite wipe. Instead you enter bootloader mode and factory reset from there. According to Trezor, the way you enter bootloader mode depends on your model:
- Trezor Model One: connect the USB cable while holding the left button.
- Trezor Model T: connect the USB cable while swiping your finger across the touchscreen.
- Trezor Safe 3: connect the USB cable while holding the left button.
- Trezor Safe 5: connect the USB cable while swiping your finger across the touchscreen.
- Trezor Safe 7: hold the power button until you see the screen light up, then connect by USB or Bluetooth.
Once in bootloader mode, follow the on-screen prompts to select Factory reset and confirm. Because bootloader steps can vary slightly between firmware versions, it’s worth following Trezor’s official per-model guide alongside these steps. After the reset you’ll reinstall firmware if prompted, then restore your wallet from your seed and set a new PIN.
A word of caution: entering the wrong PIN repeatedly will also wipe the device on its own, once you pass the model’s attempt limit. If you’re still guessing, stop and list your likely PINs on paper first, so a wipe happens on your terms and not by accident.
How to Restore Your Wallet After a Factory Reset
Once the device is blank, restoring is straightforward as long as your seed is correct.
- Open Trezor Suite with your device connected and choose “Recover wallet” during setup.
- Enter your recovery seed in the exact order you wrote it down.
- Set a new PIN when prompted.
- If you used a passphrase, enable it and enter it to reach your hidden wallet.
- Enable any coins or accounts that don’t appear automatically.
Your balance reappears because it was never gone, only the local keys were. For a full walkthrough of the restore process and the common errors that come up, see our Trezor wallet recovery guide.
Factory Reset Didn’t Fix It? Common Issues
Most resets go smoothly, but a few things trip people up afterwards:
An “invalid seed” error during restore usually means a word is misspelled, in the wrong order, or hard to read on your backup. Our guide on a lost or invalid Trezor seed phrase covers how to fix this and what’s possible if a word or two is missing.
An empty wallet after a correct seed almost always means a passphrase is involved. Your funds are sitting in a hidden wallet that only the passphrase can open.
If you wiped the device without a complete backup and now can’t restore, be very careful with anyone promising a guaranteed fix. An honest Trezor recovery service will assess your case first and tell you the real odds before any work begins.
Trezor Factory Reset FAQ
Does a factory reset delete my crypto?
No. Your coins stay on the blockchain. A factory reset only erases the wallet and PIN stored on the device, and you regenerate them from your recovery seed when you restore.
Can I factory reset a Trezor without the PIN?
Yes. If you’ve forgotten the PIN, you reset through bootloader mode instead of Trezor Suite. You still need your recovery seed afterwards to restore access, so confirm you have it before wiping.
Will I lose my crypto if I reset without a backup?
Yes, permanently. Without your recovery seed (and passphrase, if you set one), a wiped wallet cannot be restored by you, by Trezor, or by anyone else. Never wipe a device unless your backup is complete and readable.
How do I factory reset a Trezor Safe 5?
Unlock the Safe 5 with your PIN, open Settings via the gear icon in Trezor Suite, go to the Device tab, scroll to the Danger Area, tap “Wipe device,” and confirm on the Safe 5’s touchscreen. If you’ve forgotten the PIN, connect the cable while swiping the touchscreen to enter bootloader mode and choose Factory reset there.
Does a factory reset remove the firmware?
A standard wipe through Trezor Suite keeps the firmware and only removes your wallet data. A factory reset performed in bootloader mode can also clear and reinstall firmware, which is why you may be prompted to install firmware again before restoring.
How many times can I factory reset my Trezor?
As many times as you like. Wiping and restoring does not wear out or harm the device, provided you always have your recovery seed before you wipe.
