Our code lock offers the function of setting a temporary access code, which is ideal for people needing one-time or periodic access to your home or office.

In the mobile application, you can easily generate a temporary code that will be valid for a specific period. Simply select the type of code (recurring or one-time), enter a six-digit code or generate it randomly, name the code, and set its activation and expiration dates.

For example, if you expect a service technician, you can generate a one-time access code valid only for the duration of their visit. After generating the code, you can share it via SMS, email, or copy and send it in your preferred way. Thanks to this feature, guests can easily and securely gain access without the need to provide permanent codes.

The Spreest code lock is distinguished by its water resistance, making it an ideal solution for both indoor and outdoor applications.
