Abstract

A vehicle security system includes a main printed circuit board (PCB) assembly, a radio frequency identification (RFID) assembly, a starter assembly, and an RFID tag. The main PCB assembly may be configured to determine whether an activation sequence of a motor vehicle is correct, whether an RFID tag is in close physical proximity to the RFID reader, and whether the RFID tag is a valid RFID tag. The main PCB assembly may transition the vehicle security system into a disarmed state to allow the starter assembly to start the motor vehicle in response to determining that the RFID tag is valid. The main PCB assembly may deactivate a critical component of the motor vehicle in response to determining that the activation sequence is not correct, that that the RFID tag is not in close physical proximity, or that that the RFID tag is not valid.

Dependent claims

A vehicle security system, comprising:

a main printed circuit board (PCB) assembly;
a radio frequency identification (RFID) reader coupled to the main PCB assembly;
a starter assembly coupled to the main PCB assembly;
and
an RFID tag,
wherein the main PCB assembly is configured to:
determine whether an activation sequence of a motor vehicle is correct;
determine whether an RFID tag is in close physical proximity to the RFID reader and whether the RFID tag is valid in response to determining that the activation sequence of the motor vehicle is correct;
and
transition the vehicle security system into a disarmed state to allow the starter assembly to start the motor vehicle in response to determining that the RFID tag is in close proximity to the RFID reader and valid.
