Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Keyless Entry Antennas
The keyless entry antennas are used to transmit and receive RF communication with the keyless entry transmitters when accessing the vehicles doors or rear compartment.
The antennas are controlled by the remote control door lock receiver (RCDLR). When an exterior door handle switch or exterior rear compartment lid release switch is pressed, the respective antenna sends out a challenge to the transmitter, which begins the passive entry communications.
The keyless entry antenna backup is located in the glove box area. It has a small pocket next to it where the key fob can be inserted if the key fobs battery is dead, weak or the radio frequency (RF) signal is being jammed.
The purpose of the keyless entry antenna backup is to send a low frequency RF challenge to a programmed key fob, inside the interior of the vehicle, when the start button is pressed. The keyless entry antenna backup is controlled by the RCDLR.
