A remote keyless entry (RKE) fob is an electronic

Explanation:
A remote keyless entry fob is designed to send a signal. When you press a button, the fob generates a coded radio frequency signal and transmits it to the vehicle. The car has a receiver that picks up that signal and, if the code matches, carries out the requested action (like unlocking the doors). So the fob’s primary role is as a transmitter, not a receiver, sensor, or amplifier. The other options don’t fit because they describe functions that aren’t what the fob does: it doesn’t primarily receive signals, sense proximity or input, or boost signals.
