A dongle module to be installed in a vehicle is discussed. The dongle module has memory buffers and processors. The dongle module also has a first transceiver that couples the on-board diagnostic (OBD) port of the vehicle to communicate with a fault and diagnostic module of the vehicle. A second transceiver uses wireless communications to communicate with one or more client devices. An RF transmitter transmits RF signals to Remote Keyless Entry (RKE) module of the vehicle. A mapping module either include a first map calculating chip to calculate map coordinates of the vehicle, or periodically receive map coordinates from a client device. A security module is configured either to receive, or to implement an algorithm to determine, a rolling security key of the RKE module of the vehicle. The security module also receives commands to be transmitted by the RF transmitter to the RKE module to be executed.
