Abstract
A key fob simulator for sending actuation command to a vehicle is discussed. The key fob has memory buffers, processors, and a transceiver that uses wireless communications to communicate with a backend cloud-based system. A RF transmitter of the key fob can transmit RF signals to Remote Keyless Entry (RKE) module of the vehicle. A mapping module includes a map-calculating circuit to calculate map coordinates of the key fob. A security module can receive a rolling security key of the RKE module of the vehicle. The key fob includes buttons that can be pushed by a user of the key fob to generate actuation commands by the security module. Using the RF transmitter, an actuation command and the rolling security key can be sent from security module to the RKE module of the vehicle. The RKE module then executes the actuation command after validating the rolling security key.
