Unauthorized door unlocking via replayed rolling codes
Published Jan 3, 2023 · Updated Apr 10, 2025
Authentication bypass in the Renault ZOE 2021 remote keyless system allows physically proximate attackers to unlock vehicle doors. The receiver accepts previously captured 433.92 MHz door-open transmissions because each request draws from the same rolling-code set rather than rejecting a reused code. An attacker must be close enough to capture and retransmit the key-fob signal; the published evidence establishes unauthorized door unlocking, not vehicle startup.
