    How to Transfer TTLock to a New Phone (or New Owner)

    Signing in to your existing account on a new phone keeps every lock, passcode and eKey exactly as it was — locks live in the cloud, not on the handset. Transferring a lock to a genuinely new owner is a different job: it means unbinding the lock from your account and having the new owner add it fresh, which wipes the passcodes and eKeys you had set up.

    What you need

    • Your account login. The email or phone number and password used when the locks were first added.
    • A new phone with Bluetooth and internet. Smart Lukko is an independent third-party app for TTLock-compatible locks, not affiliated with TTLock/Sciener, and it works the same way on any recent Android or iOS handset.
    • For a real ownership transfer: the new owner's own account, and physical access to the lock so it can be re-added after being released.

    Step-by-step

    Keeping the same owner, just a new phone

    1. Install the app on the new phone and sign in with the same account credentials you used before — do not create a new account.
    2. Let it sync. All locks, eKeys, passcode records and access logs are stored against your account in the cloud, so they appear automatically once the app finishes syncing, with no need to re-scan any lock.
    3. Re-pair Bluetooth only if a lock refuses to unlock directly. The lock list appears immediately, but the first close-range unlock may need the phone to complete a Bluetooth handshake, which happens automatically.
    4. Sign out of the old phone if you are retiring it, especially if it is being sold or handed to someone else.

    Transferring ownership to someone else

    1. Decide what the new owner needs. A full transfer means they become the admin who can add and remove other users; anything less can be handled with a shared eKey instead.
    2. Delete the lock from your account. Open the lock's settings and remove it. This unbinds the lock and clears your admin rights over it.
    3. Have the new owner scan and add it. Once unbound, the lock goes back into pairing mode and shows up in any app's add-device list, letting the new owner bind it to their own account as the new admin.
    4. Rebuild access from scratch. The new owner sets fresh passcodes, cards, fingerprints and eKeys; nothing carries over from the previous account.

    Checklist before selling a property or lock

    TTLock-compatible locks are single-owner devices, so leaving one bound to your account after a sale hands you permanent, invisible access to the buyer's door.

    • Delete every passcode, card and fingerprint you or previous tenants set up, not just your own.
    • Revoke all eKeys shared with cleaners, contractors, guests or family.
    • Unbind the lock from your account as the final step, right before handover, so it does not sit unpaired and vulnerable for long.
    • Confirm with the buyer that they can see and add the lock before you leave the property.
    • Remove the gateway too if one is included in the sale, and unbind it from your account the same way.

    Common mistakes

    • Creating a new account on the new phone. This starts you from zero with no locks; always sign in with the original credentials instead.
    • Assuming a factory reset transfers ownership. A reset only clears the lock's own memory; the account binding is separate and must be released from the app.
    • Forgetting shared eKeys still work after a sale. Anyone you granted access to before the sale keeps it until you revoke it or the lock is unbound.
    • Not telling the new owner to expect a factory-reset-like blank slate. After a real ownership transfer they must re-add every passcode and user themselves.

    Frequently asked questions

    Do I lose my locks if I switch to a new phone?

    No. Locks are tied to your cloud account, not the phone. Sign in with the same credentials on the new device and everything reappears automatically.

    How do I transfer a lock to a new owner?

    Delete the lock from your account to unbind it, then have the new owner scan and add it from their own app. This makes them the new admin but clears all existing passcodes and eKeys.

    What should I do before selling a house with a smart lock?

    Delete all passcodes, cards and fingerprints, revoke every shared eKey, and unbind the lock from your account right before handover so the buyer can add it fresh.

    Does a factory reset transfer the account ownership too?

    No. A factory reset clears the lock's local memory but does not release the account binding. You still need to delete the lock from your app for it to become available to someone else.

    Can I keep a shared eKey active after selling the lock?

    Once the lock is unbound and re-added by a new owner, previously shared eKeys stop working because they were issued against the old admin account.
