The key that no longer opens for a remote thief
Relay-theft proof — over standard BLE.
Today a thief with a simple relay box opens and starts a keyless car in milliseconds, several metres away, without a trace — now the majority of thefts. The BRANXA smart key tells a real presence from a relayed signal and only delivers the opening verdict in hardware, fail-safe: the door stays locked until presence is genuinely confirmed. All over standard BLE — no costly UWB chip.
- Anti-relay: the most common attack, neutralised
- Anti-cloning / anti-replay: an authorisation can't be replayed
- Opens only on a wired verdict — locked by default
Beyond the car: building access, fleets, sensitive sites and defence.
