Frequently Asked Questions

How does a passive lock work without power?

The passive lock does not require an internal battery or wiring. It receives the necessary power for operation directly from the smart electronic key during contact.

What happens if a smart key is lost?

Lost or stolen keys can be immediately blacklisted and disabled through the management software, ensuring they can no longer be used to open any locks in the system.

Can I track who opened a specific lock?

Yes. Every unlock and lock event is recorded by the smart key. Once the key is synced with the software, you can view detailed logs of who accessed which lock and at what time.

Is the system suitable for outdoor use?

Absolutely. The locks feature an IP64 protection level and the keys are IP67 rated, designed to operate in harsh environments ranging from -40°C to 80°C.

Can one key open different types of locks?

Yes, the system is designed so that a single smart key can be authorized to open various types of locks (padlocks, cabinet locks, etc.), reducing the burden of carrying many physical keys.

Do you provide management software?

We offer both a free standalone version of the management software and a paid web-based version with advanced features and remote authorization capabilities.
