On a Lockin Veno Pro, anti-peep PIN entry is ready to use: enter random digits before and/or after your real PIN, while keeping the real PIN together and keeping the complete entry at 20 digits or fewer. The keypad checks the valid PIN within the longer sequence, so someone watching cannot easily learn the exact PIN from the digits you enter.
This is a PIN-entry feature, not a separate setting you need to turn on. It is also not available for every credential type. The Veno Pro manual specifically says that one-time passcodes do not support anti-peep entry.
How do you use anti-peep PIN entry on a Lockin smart lock?
- Confirm the credential type. Anti-peep entry is for a regular user PIN or a supported recurring or duration passcode. If the code is a one-time passcode, enter it exactly as issued without extra digits.
- Wake the keypad. Touch the exterior keypad as instructed by the Veno Pro manual. The wake-up touch is separate from the PIN itself, so do not count it as a masking digit.
-
Enter optional masking digits. Add one or more random digits before the real PIN, after it, or on both sides. For example, if the real PIN is
246810, a valid masked entry could place random digits before and after246810. - Keep the real PIN unchanged. Do not reorder, split, or edit the actual PIN. The masking digits surround the real sequence; they do not replace any part of it.
- Stay within the total limit. The real PIN and all masking digits together must be no more than 20 digits.
- Wait for the lock’s response. If the entry is rejected, stop and verify the credential type and PIN with the owner instead of trying many guesses.
The exact keypad confirmation behavior can vary with the model, firmware, and manual revision. Follow the response shown or announced by your lock.
What is an anti-peep PIN?
Anti-peep PIN entry is sometimes called password masking. It lets you enter extra numbers around the valid PIN. The important part is that the real PIN remains a continuous, unchanged sequence inside the longer entry. Do not treat the 20-digit limit as 20 extra digits; it is the total length of the entry.
Which Lockin PIN types support anti-peep entry?
The credential type matters more than the fact that it is called a “guest code.” The Veno Pro manual documents the following distinction:
| Credential type | Anti-peep entry | Practical instruction |
|---|---|---|
| Regular user PIN | Supported | Surround the PIN with random digits. |
| Periodic or recurring passcode | Supported | Use masking digits while the passcode remains active. |
| Duration passcode | Supported | Use masking digits during the configured access period. |
| One-time passcode | Not supported | Enter the issued code exactly as provided. |
If an owner sends a temporary code, ask whether it is one-time, periodic, or duration-based before you try to use masking digits. Lockin’s separate one-time-code guidance also explains that a one-time PIN should be entered unchanged.
What should you do if a masked PIN does not work?
- Check the code type. A one-time passcode will fail if you add masking digits.
- Check the real PIN. Make sure the valid PIN is complete, in the right order, and not split by an accidental extra digit.
- Check the total length. Count the real PIN and masking digits together; the Veno Pro limit is 20 digits total.
- Wake the keypad correctly. A touch that only wakes the keypad should not be mistaken for part of the PIN.
- Avoid repeated guesses. Wrong password attempts can trigger temporary password lockout and an app alert.
- Use an authorized fallback. If you are the owner, use another enrolled method such as palm-vein recognition, fingerprint, the Lockin Smart App, or the mechanical key where available. If you are a guest, contact the owner rather than asking for or posting the PIN publicly.
Do not reset the lock just because one masked entry was rejected. First confirm the model, credential type, code validity, and digits you entered.
Does every Lockin smart lock use the same anti-peep rule?
No universal rule should be assumed. Lockin’s Veno Pro product page and user manual support the Veno Pro instructions above, while Lockin’s manuals page lists separate manuals for Veno, Veno Go, Veno Plus, and the Veno Solar models. Feature names and credential limits can differ by model or manual revision.
Before using masking digits on another Lockin smart lock, open the matching Lockin user manual and check its password instructions. For the Veno Pro, the current Lockin Veno Pro product page also lists PIN code alongside palm-vein, fingerprint, app, and mechanical-key access methods.
Bottom line
To use anti-peep PIN entry on a Lockin Veno Pro, wake the keypad, enter optional random digits around the unchanged real PIN, and keep the complete entry within 20 digits. Do not add masking digits to a one-time passcode. If the entry fails, verify the credential type and PIN before trying again, because repeated guesses can trigger wrong-try protection.
For model-specific setup or a credential problem, check the Lockin FAQ or the Lockin user-manual library. Never share an active PIN in a public support comment.
