A remote keyless entry fob is best described as

• A. Receiver
• B. Antenna
• C. Transmitter
• D. Keypad

Answer: (C)

The remote keyless entry fob is best described as a transmitter. When you press a button on the fob, it generates and sends a coded radio signal to the vehicle. The car has a receiver that captures this signal, validates the code, and then performs the requested action (like locking or unlocking the doors). The fob itself isn’t primarily a receiver, and while it may have an antenna to carry the signal, its main function is to transmit. It also isn’t a keypad—the fob’s primary role is sending signals, not providing a manual input surface.
