: Diagnostic tools must request a cryptographic security token directly from official servers.

The vulnerability primarily impacted Renault models manufactured over the last decade that utilize the standard hands-free card system. Vehicles most susceptible to this exploit included: (Generation IV and V) Renault Captur Renault Mégane (Generation IV) Renault Kadjar Renault Zoe (Early to mid-generation EV models)

For years, Renault models (notably the Clio, Captur, and Megane) were susceptible to attacks where a dongle would "spoof" a valid key signal or force the into an auto-programming mode. This allowed unauthorized users to drive away in minutes. The "Patch": Secure Gateway (SGW)
