The keyfob unit includes a BLE system-on-chip (SoC) configured to facilitate communication, perform encryption, and execute control logic operations. The system includes user input buttons configured to trigger commands and perform mode switching between a Passive Keyless Entry (PKE) mode and an Active Keyless Entry (AKE) mode. A nonce generator is configured to generate nonce values and an encryption module implements a rolling nonce-based encryption for preventing replay attacks and ensuring secure communication. The system dynamically adjusts transmission power based on the command type and continuously includes battery percentage in all transmitted messages. [FIG. 1]
