Keyless Entry Keypad
The RFA module sends voltage signals on 3 separate circuits to the keyless entry keypad. When an individual keypad button is touched, an individual or combination of the input circuits is routed to ground. Based on these inputs, the RFA module determines which button was touched and locks/unlocks the door (s) or opens the luggage compartment lid.
When a keypad button is touched, the buttons illuminate to provide better visibility. The keypad also illuminates any time the illuminated entry feature is active. If the lock all doors command is entered or 5 seconds have elapsed since the last button press, the keypad illumination turns off.
The keyless entry keypad can be used to:
- unlock the driver door.
- unlock all the doors.
- lock all the doors.
- program/erase the customer key code.
Vehicles equipped with a keypad are programmed with a 5-digit entry code. This code is provided to the customer through a wallet card in the Owner's Literature. In addition, this code is available through a scan tool and is printed on the BCM label. When entering codes, each digit must be entered within 5 seconds of the previous button press.
Locking the Doors with the Keyless Entry Keypad System
It is not necessary to enter the factory set or personal code prior to locking all doors. To lock all doors, touch and hold the 7/8 and 9/0 buttons at the same time for approximately 2 seconds.
Unlocking the Doors with the Keyless Entry Keypad System
To unlock the driver door, enter either the factory set code or a personal code (each digit must be pressed within 5 seconds of the prior digit). The illuminated entry feature activates unless disabled.
To unlock all doors, enter the factory set code or a personal code (driver door unlocks) and then touch the 3/4 button within 5 seconds. This feature can be changed to a 1-step unlock so that all of the doors unlock when a valid code is entered. REFER to Stepped Unlock Programming .
Anti-Scan Feature
To provide added security, the keypad is disabled for 1 minute after 35 button presses without a valid entry code being entered. The keypad flashes during this 1 minute mode with all functionality disabled except for 7/8 and 9/0 still being allowed to lock the vehicle.
Anti-scan turns off after 1 minute of keypad inactivity, the unlock button is pressed on a RKE transmitter, or the ignition is switched to RUN.
Keyless Entry Keypad Memory Seat Feature
The keypad provides a memory seat, mirror, and adjustable pedal recall feature. The feature is associated with the personal entry codes and positions the driver seat, exterior mirrors, and adjustable pedals to the memory 1 or memory 2. REFER to Keyless Entry Keypad Code Programming and Remote Memory Activation for programming the keypad code to a memory setting.
Factory Keycode Retrieval
The factory keycode for the keyless entry keypad can be retrieved from a label on the BCM or using a diagnostic scan tool.
