Manage you properties using our end-to-end access management systems.

Manage your property from anywhere

Control is now in your hands. With our lockn app, grant access to visitors even when you are away from home. Have multiple SIMSIMs? - our app manages all of them.

Make home access safer and smarter

With SIMSIM, be assured that only the ones you welcome can enter your home. Time-sensitive PIN codes and bluetooth keys let you decide how long you want to allow access for.
