We respect your Privacy. We don’t collect or store your credentials. Your e-key is stored encrypted in your smartphone safely, and we don’t have the key. Besides, we don’t collect your audit trail; only you can view the audit trail on your smartphone.

What if I forgot to carry my phone? How to get in my house?

Mechanical key override is available for your locks.

What if I lost my phone? Can I revoke it?

Each phone can be revoked individually.

Do I need to reset the whole system if any member lost his/her phone?

No, just revoke his/her access right.

Will I still be able to enter my house if power outage?

Most locks use batteries . And again, your mechanical key are still usable.

What is the battery life of locks?

It depends on how you use the lock, but typically it will last for more than 1 year on 4x AA alkaline batteries.

What happen if the battery is dead?

Before the battery is dead, there are warning such as LED/beeps. Besides, you can view the battery status from the app. If the battery is dead, and the lock provides emergency charging interface externally, you can gain power by connecting a 9V battery. And again, your mechanical key are still usable.

Will I still be able to unlock if Internet is unavailable?

Yes. The solution doesn’t rely on Internet for unlocking. And you can even perform management through NFC synchronization each time you tap the lock.

What happen if my smartphone battery is completely exhausted?

We need the smartphone on for the Key Butler to communicate with the lock. Since NFC consumes very little power, a quick charge (a few minutes) will be enough to enable Key Butler. Or you can use other methods such as mechanical key to unlock temporarily.

What if I doesn’t have a NFC smartphone?

An electronic lock can have multiple ways to unlock. It almost always has a mechanical key option. And since NFC is using the similar technology as MIFARE card, a card might be a temporary before you get yourself a NFC smartphone. And it might be possible to have password-combination (push-button, or touch-button), or even a fingerprint-sensor on the same lock., if available.

Can the lock support legacy functions such as Card, Touch, or Fingerprint?

Sure. It depends on lock design. Among these, since MiFARE cards are using same technology as NFC, it’s always supported on every NFC lock.
