Yes—if your Lockin model includes a mechanical key cylinder, you can use its physical key even when the Lockin Smart App is unavailable. For the current Lockin Veno series, the official FAQ says the lock includes two mechanical keys for physical unlocking. The key is a local, at-the-door backup; it does not depend on signing in to the app or reaching your Wi‑Fi network.
That answer has one important boundary: the key must match the lock, the key cylinder must be accessible, and the door hardware must be operating normally. Keep the key somewhere an authorized adult can reach without relying on the app.
What still works when the app is unavailable?
The app and the physical lock do different jobs. The Lockin Smart App is used for setup, access management, settings, activity information, firmware updates, and remote control on supported models. A physical key operates the mechanical cylinder at the door.
| Situation | Physical key | App-based action | Practical next step |
|---|---|---|---|
| Your phone is unavailable or the app will not open | Yes, if you have the matching key | Unavailable | Use the key at the lock |
| Wi‑Fi or internet is down | Yes | Remote control may be unavailable | Use the key or another already enrolled local method |
| The lock battery is depleted | Yes, according to the Veno FAQ | Electronic methods need power | Use the key, or temporarily power the exterior Type-C port |
| The key is missing or does not turn | Not until the key or cylinder issue is resolved | May still work if the lock and connection are available | Do not force the key; contact Lockin support or a qualified locksmith |
The exact local methods vary by model. For example, the Veno Pro product page lists palm-vein recognition, fingerprint, PIN code, mechanical key, and app control. Veno Solar Palm lists palm vein, PIN, app control, mechanical key, and voice control. Smart-home controls and app features can have separate network or controller requirements, so they should not be treated as a replacement for a physical-key plan.
How to use the physical key on a Lockin Veno
The keyhole is concealed, so it may not be visible during normal use. Use the steps for your model below.
Veno Pro, Veno Plus, and the video Veno series
- Find the doorbell button on the exterior assembly.
- Open the doorbell cover to reveal the mechanical keyhole.
- Insert one of the supplied mechanical keys.
- Turn the key to unlock the door.
Lockin’s FAQ identifies the mechanical keyhole as being inside the exterior doorbell button and recommends keeping the two supplied keys in a secure place. It suggests storing one as an emergency backup in a car, provided that location is safe and appropriate for your household.
Veno Solar Palm
- Press the solar-panel release button on the side of the front assembly.
- Lift the panel and pull it outward to expose the hidden compartment.
- Insert the physical key into the mechanical cylinder.
- Turn the key to unlock the door.
Veno Solar Face uses the same concealed-key idea, but always confirm the instructions for the exact model and revision in the current Lockin user manual.
App outage versus dead battery: do not confuse them
An unavailable app does not automatically mean the lock has no power. If the lock still has power, its enrolled local methods—such as a PIN, palm-vein profile, or fingerprint where supported—may remain available even if remote app access is not.
A dead battery is different. The Veno-series FAQ gives two emergency options: use the backup mechanical key, or connect a temporary power source to the exterior Type-C port. A power bank and suitable cable can restore enough power for an electronic entry attempt, but the key remains the simplest direct backup when you have it.
For Veno Solar models, solar assistance is still battery charging support, not a guarantee that the battery can never run down. Placement, usable light, weather, usage, and battery state affect charging. Keep the physical key available even if you chose a solar-assisted model.
What to check before you need the backup key
Make the backup plan part of installation rather than waiting for an outage.
- Confirm that your exact Lockin model has a mechanical key cylinder and locate it while the door is open.
- Test the supplied key gently before relying on it. If it does not insert or turn smoothly, stop and check alignment or the manual.
- Give the key to an authorized person, but do not leave it beside the door or in an obvious outdoor hiding place.
- If you live with family members, decide who can access the spare and where it is stored.
- Keep a power bank and the appropriate Type-C cable available if your model supports exterior emergency power.
- Check the current Lockin user manual library and Lockin FAQ for model-specific instructions.
If you are choosing a Lockin model, compare the access and power plan—not just the app features. The Veno Pro page lists mechanical-key access alongside biometric, PIN, and app methods. The Veno Solar Palm page shows the concealed key cylinder and lists USB-C emergency power. Confirm door fit and the exact model before purchase.
Can the app disable the physical key?
No app setting should be assumed to revoke a mechanical key. Digital passwords, fingerprints, and palm-vein entries can be managed in the Lockin Smart App on supported Veno models, but a physical key is a separate mechanical access path. If a key is lost, treat it as a physical-security issue: contact Lockin support or a qualified locksmith about the appropriate remedy. See the related guide, Can the Lockin App Disable a Lost Mechanical Key?, for that separate question.
Bottom line
Yes, a compatible Lockin Veno smart lock can still be opened with its physical key when the app is unavailable. The key is independent of app login and remote connectivity, and the Veno FAQ also lists it as an option when the battery is depleted. Locate and test the key during setup, store it securely for authorized access, and use the current model manual when the cylinder is concealed or the lock does not respond normally.
