Keyless Entry System Description and Operation - Passive

Passive keyless entry allows entry to a locked vehicle without pressing any buttons on the keyless entry transmitter. You must only have the transmitter with you. This passive system is also part of the vehicle starting system. It allows you to start and run the vehicle having only the transmitter as your key. The passive entry and starting system uses low frequency aerials in several different areas on the vehicle to determine the location of the transmitter. When passively opening a locked door or the tailgate, you must have a programmed transmitter with you in your pocket, purse, or briefcase. As a customer opens the door handle or presses the tailgate touch pad, the low frequency aerial sends out a request to the keyless entry transmitter. The transmitter should be in a one metre range of the door or tailgate in order to receive the request. If the request is met, the transmitter will respond, allowing the door to be unlocked and opened. Passive entry allows you to operate the following features:

The keyless entry control module will detect the keyless entry transmitter and when an exterior door handle is pulled and the transmitter is within 1 metre (3 feet) of the door handle, the body control module (BCM) will unlock the doors and send the unlatch enable signal to keyless entry control module. When any exterior door handle is lifted, switched ground signals are sent to the keyless entry control module through the door handle switch signal circuits. Upon receipt of these inputs, the keyless entry control module will check the door lock status of the system as described above. Once the enable criteria have been met, the keyless entry control module will supply power and ground to door catch control circuits and the door will release.
