TTLock eKey: how to send and manage eKeys

An eKey is an app-based unlock permission, separate from a keypad passcode — it lets someone open the lock with their own phone over Bluetooth, without ever seeing a code. Smart Lukko is an independent third-party app for TTLock-compatible locks, not affiliated with TTLock or Sciener, and eKey sharing works the same way as it does in the official ecosystem for locks built on this platform. Before sending one, you need:

• Admin or authorised-admin rights on the lock yourself. Normal eKey holders without admin rights generally cannot share further eKeys.
• The recipient's registered account identifier — the phone number or email they used to sign up in the app.
• The recipient's app already installed, with an account created. An eKey cannot be sent to someone who has never registered.
• An internet connection to send the eKey, since it is delivered through the account system in the cloud, not over Bluetooth.

1. Open Smart Lukko and select the lock you want to share.
2. Tap eKey or Manage users, then Send eKey.
3. Enter the recipient's registered phone number or email exactly as they used it to sign up.
4. Choose the eKey type: Permanent for indefinite access, Timed for a fixed start/end window, One-time for a single unlock, or Recurring/cyclic for repeating windows such as every weekday.
5. Decide whether to grant admin (authorised admin) rights. This lets the recipient add and remove other users, generate passcodes, and manage the lock as if they were a second owner — only extend this to someone fully trusted.
6. Confirm and send. The eKey appears in the recipient's app once they refresh or reopen it.
7. Tell the recipient to accept or check the eKey in their app; on some accounts a new eKey needs a pull-to-refresh on the device list before it becomes usable.

• Permanent eKey. Works indefinitely until manually revoked. Suited to household members or long-term staff.
• Timed eKey. Active only between a start and end date/time, then expires on its own. Good for contractors or tenants with a known move-out date.
• One-time eKey. Valid for a single unlock, then deactivates.
• Recurring/cyclic eKey. Repeats on a schedule — for example every weekday between set hours — useful for regular cleaners or delivery staff.

Separately from validity type, every eKey is either normal or admin (authorised admin). A normal eKey only unlocks the door. An admin eKey can additionally manage the lock's users, passcodes and settings, mirroring what the original owner can do. Authorised-admin status is powerful and should be limited to co-owners or trusted managers, since it can be used to add further eKeys or remove existing ones, including yours in some ownership setups.

• Mistyping the recipient's identifier. The eKey is matched to an exact account; a typo in the phone number or email sends it nowhere and the recipient never sees it.
• Assuming the recipient can accept without an account. If they have not registered in the app yet, ask them to sign up first, then resend the eKey.
• Granting admin rights by default. Most guests and short-term users only need a normal eKey; reserve admin rights for people who genuinely need to manage other users.
• Expecting instant delivery without internet. Both the sender and recipient need connectivity when the eKey is sent and first synced; it is not a Bluetooth-only handoff like a passcode.
