The keyless entry system is a vehicle entry device. The keyless entry system is used in conjunction with the door locks to unlock the vehicle. Keyless entry will lock / unlock the doors / liftgate, operate the power liftgate (if equipped), or release the liftglass when a corresponding button on the keyless entry transmitter is pressed. This is accomplished by the transmitter sending a radio frequency to the remote control door lock receiver (RCDLR). The RCDLR interprets the signal and activates the requested function via a serial data message to the body control module (BCM). A low transmitter or vehicle battery or radio frequency (RF) interference from aftermarket devices, such as 2-way radios, power inverters, computers, etc., may cause a system malfunction. High RF traffic areas may also cause interference that could lead to a malfunction. Keyless entry allows you to operate the following components:

  • The door and liftgate locks
  • The power liftgate (if equipped)
  • The liftglass
  • Remote vehicle starting (if equipped)
  • The illuminated entry lamps

The keyless entry system has the following components:

  • The keyless entry transmitters
  • The keyless entry antenna (located in the vehicle glass)
  • The BCM
  • The RCDLR
