RFID Smart Start Stop Button System

Operating voltage: DC 12V only (not compatible with 24V systems). Standby current: 8mA — supports up to one month of continuous standby. Button display: blue LED indicator (off during anti-theft mode; flashes when exiting anti-theft state). Dimensions, weight and material: compact black ABS housing; precise measurements not specified in source, but designed for universal fit in A0-class cars, caravans and aftermarket installations. Core functionality includes RFID-based keyless engine start/stop via push button, automatic engine immobilisation 15 seconds after ignition-off, remote-free anti-theft activation/deactivation using an ID sensor card near the induction coil, brake-light-triggered alarm (15-second flash on illegal brake application), and dual-stage brake light output (4 flashes then steady-on when brake pedal is pressed). The system integrates seamlessly with existing vehicle wiring — no original key required for operation once installed. Designed for three main use cases: (A) vehicles without factory remote or anti-theft (e.g., basic caravans or entry-level A0 cars), adding full keyless start/stop, silent lock anti-theft, brake flash and brake alarm; (B) vehicles already fitted with basic anti-theft (e.g., mechanical locks, PLC alarms), where this system adds hidden layer protection and intelligent control; (C) vehicles equipped with PKE smart entry — enhances intelligence and user experience while retaining all core functions.
