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 Transmitters
The keyless entry transmitters are used to actively lock and unlock the vehicle doors, release the trunk, initiate a remote start event, and to initiate a panic alarm.
The transmitters can also be used passively to enter and start the vehicle. By pulling either of the front exterior door handles, a nearby programmed transmitter is challenged via the door antennas. The transmitter will respond by sending an RF signal to the RCDLR via its external antenna located in the back glass; the RCDLR will then interpret this communication and either allow entry into the vehicle or deny it.
Regardless of whether the transmitter is responding to an active function (button press on the fob) or a passive function (starting the vehicle), the transmitter ALWAYS responds via RF to the RCDLR's external antenna.
