Each of these systems involves the adoption of appropriately sized locks and handles with additional content, such as soft close or automatic opening/closing.

Handles, in particular, must be designed with both styling and ergonomic and functional requirements in mind, with the result that there are particularly varied shapes on the luxury sports car market.

Since this is a security system, various reliability and regulatory requirements come into play in the design and development stages, and these will be manned up to type-approval impacts. Each lock assembly must also be equipped with mechanical emergency releases, operable by bowden or linkages combined with key pawls (in the case of external handles, of course).
