Connected locking for modern RV platforms
Central control, app access and vehicle fleets: STS develops locking systems that become part of the vehicle electronics – starting with central locking for storage and garage hatches.
The hatch should lock when the vehicle locks
RV owners expect the same comfort they know from their car. Every hatch that needs its own key is a hatch that can be forgotten. Smart access closes that gap – and gives manufacturers a modern, integrated feature for their platforms.
Central control
Hatch locks integrated into the vehicle central locking system.
App access
Connected access concepts for owners and rental customers.
Vehicle fleets
Access management for rental and fleet operators.
M1 security
Electromechanical locking that meets the M1 standard.
