The Sigma S Series is designed to work independently as a full remote control system linked to the vehicle’s central door locking, or to interface with the manufacturer’s pre-installed remote locking system. All models are manufactured to the highest European certification standards, including Thatcham approval for the appropriate insurance-approved systems.
