A Trezor lockout always comes down to two questions: do you still have your recovery seed, and does the device still work? Those two answers determine everything, including whether the fix is a ten-minute restore or a job for a recovery bench. This guide walks through every combination, based on the Trezor cases we handle at our Trezor recovery & repair service.

Restoring a Trezor Model One, Model T, or Safe 3
Locked out of a wallet like this one?
I repair hardware wallets, crack forgotten passwords, and rebuild broken seed phrases — on my own bench in Denver.
The recovery logic is identical across every Trezor, because your coins live on the recovery seed, not the device. What differs between models is only how you enter the seed and PIN. If you're searching "how to restore Trezor Model T" or "how to recover Trezor Model One," here's the model-specific part:
- Model One: no touchscreen, so seed and PIN entry are assisted through Trezor Suite using a scrambled on-screen keypad (the device shows the layout, you click positions in Suite). Supports 12, 18, and 24-word BIP39 seeds.
- Model T: you type the seed words and PIN directly on the device's touchscreen, so nothing sensitive passes through the computer. Supports 12/18/24-word BIP39 seeds and Shamir backup (SLIP39) shares.
- Safe 3 / Safe 5: newer models, same restore flow as the Model One (Safe 3) or Model T (Safe 5) respectively, with a physical confirm button.
How many seed words do I enter, 12 or 24? Enter exactly the number your backup card has. Trezor generates 12, 18, or 24-word seeds depending on the model and the era it was set up (older Model One setups often produced 24 words; many later wallets use 12). A 24-word wallet cannot be restored from the first 12 words, and padding a 12-word seed to 24 won't work either. If your card has a partial or unclear count, that's a seed phrase recovery problem, not a data-entry one. To restore any of these, follow the seed-restore steps in the next section.
Forgot the Trezor PIN, but you have the recovery seed
This is the easy one, and it's fully solvable at home. The PIN only protects the device itself; your coins live on the seed. The procedure:
- Wipe the device. You can deliberately enter wrong PINs until the device erases itself, or wipe it directly from Trezor Suite (the device will ask you to confirm on its screen).
- Restore from seed. In Trezor Suite, choose Recover wallet and enter your 12/24-word phrase (or Shamir shares). On a Model T you enter the words on the device's touchscreen; on a Model One you use the scrambled-keyboard entry in Suite.
- Set a new PIN and your balance reappears once Suite resyncs.
Two things to know before you start: Trezor devices erase themselves after 16 consecutive wrong PIN attempts, and the delay between attempts doubles each time, so "trying PINs until something works" is only a strategy when you're choosing to wipe. If you think you might still remember the PIN, stop guessing while attempts remain and write down your best candidates first.
Trezor wiped after wrong PIN attempts
Nothing is lost. A wipe deletes the keys from the device, not from the seed. Restore from your recovery phrase exactly as above. A wiped Trezor is a blank Trezor, not a dead wallet.
No seed either? See the last section; that combination is the serious one.
Restored the seed, but the balance is zero or wrong
The most common panic after a successful restore, and it's almost never lost coins:
- Passphrase (hidden) wallets. If you ever enabled a passphrase, your coins live in a hidden wallet that only appears when you enter the exact passphrase, including capitalization and spaces. A restored seed without the passphrase shows an empty standard wallet. Try every passphrase you ever used, including "obvious" ones you might have tested once.
- Wrong seed. People with several devices or several backup cards routinely restore the wrong one. Check the receive addresses against your transaction history on a block explorer.
- Not synced yet. Give Suite time to discover accounts, and enable the coins/account types you actually used (legacy vs SegWit vs Taproot accounts are listed separately).
If you're sure the seed is right and the passphrase is the problem, partial memory of the passphrase makes it a crackable target; that's a forgotten password recovery case, and it's one we take on regularly.
Forgot the Trezor passphrase (hidden wallet)
The passphrase is the one credential on a Trezor that nothing can remind you of. It is never stored on the device, never sent to Trezor, and never written on the backup card. Trezor's own design note is that any passphrase is valid: each one derives a different wallet from the same seed, so a wrong passphrase does not fail, it opens an empty hidden wallet. That is why people with a working device, the right seed, and a forgotten passphrase see a zero balance and nothing else.
What works, in order:
- Exhaust your own memory first, exactly. Every phrase you ever used on that device, with the capitalisation, punctuation, and spacing you used at the time. A trailing space or a capital letter is a different wallet. Check each attempt against a receive address you know held coins, on a block explorer, rather than trusting the balance field while Suite is still discovering accounts.
- Do not guess on the device. Passphrase entry has no attempt limit, but it is slow, and it tempts people into random trials that teach them nothing. Write your candidates down and test them systematically.
- Search offline from fragments. With the seed written down, a passphrase can be attacked away from the device: candidates are derived and checked against your known addresses on a computer, with no limit and no risk to the hardware. That is viable when you remember the shape of the phrase, the era, or the habits you used, and it is close to hopeless when you remember nothing. It is a forgotten password recovery case, and the odds by scenario are in recovery odds by scenario.
The same logic covers "lost Trezor hidden wallet": the hidden wallet is not lost, it is one exact string away, and the seed is the thing to protect while you look for it.
Trezor not turning on
A Trezor that's broken (dead screen, bad USB port, won't power on at all) is not the same problem as a lost seed, and it's worth telling the two apart before you do anything else.
If you have the seed: you don't need the broken device at all. Restore onto a new Trezor (or any BIP39-compatible wallet) and move on. Don't pay anyone to "repair" a device whose seed you hold.
If you do NOT have the seed but you know the PIN: the coins are still inside the device, and the device can often be physically repaired enough to extract them. Broken USB-C connectors can be re-soldered; a device that powers up but can't talk to Suite is usually a connector or cable problem, so try multiple cables and ports before assuming the worst.
Trezor screen not working
A Model T with a dead display but a working board can have its touchscreen transplanted from a donor unit; we've documented a full Trezor Model T touchscreen swap step by step.
This is bench work with real stakes: one slip with a razor blade near the display ribbon and the extraction gets much harder. If the wallet holds real value, have us do it: free assessment, no fee unless your crypto comes back.
Forgot the Trezor recovery words, but the device works and you know the PIN
You're one accident away from losing everything: the working device is now the only copy of your keys. Tonight, not next week:
- Plug it in, unlock with the PIN.
- Send the entire balance to a wallet you control with a proper backup: a new hardware wallet, or a fresh software wallet while you shop for one.
- Retire the seedless wallet.
Don't create a new "backup" of the old seed by other means; just move the coins to a wallet whose seed you actually possess.
Lost the recovery words AND the PIN (or seed plus a wiped or dead device)
The honest answer: with no seed and no PIN on a wiped or destroyed device, the coins are not recoverable. That's the security model doing its job.
The recoverable variants of this situation are the partial ones, and they're worth an assessment before you give up:
- Part of the seed (missing, smudged, or misordered words) → seed phrase recovery
- A lost Shamir (SLIP-39) share out of a set → whether this is recoverable depends entirely on the threshold you chose, and most people never noted it. See what a lost Trezor Shamir share can and cannot recover
- Partial PIN or passphrase memory on a working device → constrained brute-force is sometimes viable given the attempt limits, and passphrase cracking doesn't touch the device at all
- A damaged-but-present device where you know the PIN → physical repair, as above
If you're not sure which category you're in, describe what you have; the assessment is free, and we'll tell you plainly if your case is one of the impossible ones. Choosing between backup schemes for the next wallet? See our comparison of Shamir vs. BIP-39 backups for Trezor.
