Keyless Entry Keypad: Notes

The BCM sends voltage signals on 3 separate circuits to the keyless entry keypad. When an individual keypad button is pressed, an individual or combination of the input circuits is routed to ground. Based on these inputs, the BCM determines which button was pressed. When a valid code is received, the BCM locks/unlocks the doors.

When a keypad button is pressed, the buttons illuminate. The keypad illumination turns off after 5 seconds have elapsed since the last button press. The keypad also illuminates any time the illuminated entry feature is active.

The keyless entry keypad can be used to:

• unlock the driver door.
• unlock all the doors (and the tailgate).
• lock all the doors (and the tailgate).
• program/erase up to 5 user codes.
