Pairs well with
OneKey KeyTag is a pair of titanium plates for storing your recovery phrase. Instead of writing the words on paper, you punch dots into the plate with the tool in the box. Each plate is about a quarter the size of a credit card, fireproof, waterproof, and small enough to carry.
Why metal, not paper
The paper card in your wallet box works, until one fire, one flood or one termite nest. Thailand is humid most of the year, and paper kept for years fades and crumbles on its own. Titanium has none of these problems.
More importantly, if the recovery phrase is lost, the assets in the wallet are lost with it. Nobody can recover them, not us, not anyone.
Punch dots, not letters
Every recovery word comes from the BIP39 standard list of 2,048 words, and each word has its own number. KeyTag records that number instead of the letters. Each row on the plate is one word: look the word up in the printed word list, then punch a dot in the boxes the list marks.
To read it back, add up the numbers of the punched boxes in that row, then look the total up in the list. Do that for every row and you have the full phrase. This is what keeps the plate so small, and a full backup takes only minutes.
Specifications
- TC4 titanium alloy, the same grade used in aerospace, with a melting point of 1,668 degrees Celsius
- 36 x 33.5 x 3 mm, 14 grams per plate
- One plate holds 12 words plus one spare row; the pair holds a full 24 words
- Waterproof and resistant to acids, alkalis and chemical corrosion
- Withstands extreme heat and extreme cold
- Works with any brand of wallet that uses a BIP39 recovery phrase, 12 or 24 words
Frequently asked questions
My wallet uses a 12-word phrase. Do I need both plates?
No. One plate holds all 12 words. Keep the second as a duplicate stored somewhere else, or use it for another wallet.
If someone picks up the plate, can they read the words?
They see dots, not words. Without the method and the word list, nothing can be read at a glance. But this is not encryption: anyone who knows the method can decode it, so keep the plate as private as you would keep a paper backup.
Can I fix a wrong punch?
No. A punched dot cannot be removed. Mark the dot positions for every word in the guide first, check them against your device once more, then punch.
How is this different from OneKey Lite?
OneKey Lite is an NFC card that stores the recovery phrase encrypted and needs the app and a PIN to read it. KeyTag is solid metal with no chip: no app, no power, and readable years from now with nothing but the word list. Choose Lite for convenience, KeyTag for the most durable backup, or use both together.
ONE RULE TO REMEMBER
Anyone who asks for your recovery phrase is a scammer. No exceptions.
Neither SIAMBC nor OneKey will ever ask for it, whatever reason is given: warranty claims, identity verification, system updates or account recovery. Those words are the key to your funds. Whoever has them owns your assets, and they can never be recovered.

Return and Exchange Policy
Faulty on arrival: if a device arrives defective — a broken screen, a connectivity fault — we replace it with a new one straight away. No forms, no waiting on the manufacturer.
Warranty: hardware wallets carry a 1-year warranty, and claims are handled by us rather than an overseas support queue. CryptoSafe steel backup products are sold without warranty, as stated on those product pages.
Change of mind or wrong model: we do not accept returns or give refunds, whether or not the box has been opened. We accept returns for defective products only, which we exchange within 30 days of delivery. This is a security limitation of these devices: once a device has left us, we cannot assure the next customer that it has not been interfered with.
How to arrange an exchange for a faulty item
- Message us on LINE at @siambc or email order@siambc.com before sending anything back.
- Include your order number, what is wrong, and a photo or short video.
- Send the item back to us at your own shipping cost. Once we have checked it, we exchange it.
Refunds: faulty items are exchanged rather than refunded.

How to check it is genuine
- The packaging must be undamagedCheck that the box has not been opened or damaged and that the KeyTag plates match the product photos.
- The plates must not be punched yetBoth plates must be smooth with no dots punched. If dots are already punched, do not use them and contact us right away.
- The punch color can vary by batchThe punch comes either black-and-white or all white. Both are genuine.
- Check every word before you punchFind each word's dot pattern in the chart in the guide and compare it with your written Seed Phrase before punching, because a punched dot cannot be removed.
- Keep the plates as private as your Seed PhraseAnyone who knows how to read the dots can turn them back into words, so keep the plates as safe as a paper Seed Phrase.
OneKey KeyTag FAQ
How much is the OneKey KeyTag?
2,250 ฿ at SIAMBC, an official OneKey reseller in Thailand.
Does it work with other wallet brands?
Yes. It works with any wallet that uses a standard 12- or 24-word BIP39 Seed Phrase, with no app or power needed.
How do I punch it?
Find each word's dot pattern in the chart in the guide, then press the automatic center punch onto the plate. One row is one word.
Is it fireproof?
TC4 titanium melts at 1,668°C, far above the temperature of a typical house fire, but that figure is the material's melting point, not a fire test result.
Can I record a Passphrase?
Yes. Each plate has a * row for a Passphrase, one row per plate.
Will SIAMBC or OneKey ever ask to see my Seed Phrase or KeyTag plates?
Neither will ever ask, for any reason. Anyone who asks for your Seed Phrase, or asks you to photograph or send your KeyTag plates, is a scammer.
If you have any questions, you are always welcome to contact us. We'll get back to you as soon as possible, within 24 hours on weekdays.

Which model should I choose? It depends on your phone. The Ledger Nano S Plus does not work with iPhone, and most Trezor models are view-only on iOS. Compare every model side by side.

Will anyone ask for my recovery phrase? Never. Anyone who does is a scammer.

Before you buy
Are your products genuine?
Yes. Every device we sell is new, sealed, genuine stock from authorized channels. SIAMBC has been Thailand's hardware wallet specialist since 2016 and has a physical store in Bangkok you can walk into.
This matters more than it sounds. A hardware wallet bought from an unknown marketplace seller can arrive already set up by someone else, with a recovery phrase they know. It is the one purchase where the seller genuinely matters.
How long does delivery take?
Orders normally arrive within 1 to 2 business days, depending on where you are — faster if you are in Bangkok.
Need it today? We can send it by Grab or LINEMAN for same-day delivery. Call us or message us on LINE to arrange it, pay by bank transfer, and it goes out immediately.
You are also welcome to collect from our Bangkok store.
Can I collect from your store instead?
Yes. We are in Thawi Watthana, Bangkok, open Monday to Saturday, 9:00 AM to 5:00 PM. You are welcome to come in, see the devices in person and ask questions before you buy. We answer in Thai and English. Find us here.
What warranty do I get?
Hardware wallets carry a 1-year warranty, claimed directly through us, with no waiting in an overseas support queue.
If a device is faulty out of the box, we replace it with a new one straight away. No forms, no waiting on the manufacturer.
The exception is the CryptoSafe range of steel recovery phrase backups: these products carry no warranty and cannot be returned or exchanged, as stated on their product pages.
How can I pay?
Credit card, bank transfer, or cash on delivery. You can also pay in person at our Bangkok store.
Can I set it up myself?
Yes, and you should do every step yourself. It takes a few minutes: you press every button on the device, create the wallet and write down your recovery phrase on your own.
Our step-by-step guides walk you through each step. If you get stuck, our team can answer on LINE or by phone, without ever seeing or asking for your recovery phrase.
Which model should I choose?
It depends on the phone you use and what you are protecting. The most common mistake is buying a wallet that does not work with your phone — the Ledger Nano S Plus does not support iPhone at all, and most Trezor models are view-only on iOS.
Compare every model side by side, or ask us. We will tell you honestly which one fits.
What happens if I lose my hardware wallet?
Nothing, as long as you still have your recovery phrase. The device only holds the keys — buy any compatible wallet, enter your phrase, and your crypto is back.
The real risk is losing the phrase itself. That is why we suggest keeping it on steel rather than the paper card in the box. Paper burns, water ruins it, and in Thailand termites eat it.
Will anyone ever ask for my recovery phrase?
No. Anyone who asks for it is a scammer, without exception. Neither SIAMBC nor any manufacturer will ever ask for your recovery phrase — not for a warranty claim, not for identity verification, not for a firmware update. Whoever has those words owns your crypto, and it can never be recovered.
