2 Way Advanced Remote Start Antenna

The 2 Way Advanced Remote Start antenna sends and receives radio frequency (RF) communications between the keyless entry transmitters and the remote control door lock receiver (RCDLR). The keyless entry antenna also receives RF signals from the tire pressure monitoring (TPM) sensors located at each wheel and sends this information to the RCDLR.

A coax antenna lead connects the antenna to the RCDLR. When a transmitter button is pressed, the RF signal sent by the transmitter is received by the antenna and the communications are inputted to the RCDLR. The RCDLR also sends information to the transmitters via the antenna.
