Method and system for false lock free autonomous scan in a receiver is disclosed. The method includes identifying a presence of a desired signal to avoid false frequency lock in a Frequency Modulation receiver. The method includes receiving a signal. The method further includes identifying the desired signal, if a first energy is above a first threshold. The method also includes identifying the desired signal, if an Intermediate Frequency count is below a second threshold. The method includes identifying the desired signal, if a second energy of the signal is above a third threshold. The method includes identifying the desired signal, if an absolute difference between a first Received Signal Strength Indication (RSSI) value and a second RSSI value of the signal is below a fourth threshold. The method includes determining a third energy. The method includes identifying the desired signal, if the third energy is below a fifth threshold.
