Keyless Entry Keypad

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.

Locking the Doors with the Keyless Entry Keypad 

It is not necessary to enter the factory set or personal code prior to locking all doors. To lock all doors, press the 7/8 and 9/0 buttons at the same time for approximately 0.5 second. The locking function is disabled when the driver door is open.

Unlocking the Doors with the Keyless Entry Keypad 

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.

If the 2-stage unlock is enabled, enter the factory set code or a personal code (driver door unlocks) and then touch the 3/4 button within 5 seconds to unlock all doors. This feature can be changed to a 1-stage unlock using the message center settings.

Anti-Scan Feature 

To provide added security, the keypad is disabled for 1 minute after 36 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 valid programmed RKE transmitter, a passive entry feature is used, or the ignition is turned on.

Factory Keycode Retrieval 

The factory keycode for the keyless entry keypad can be retrieved from a label on the BCM, a wallet card in the Owner's Literature, using a diagnostic scan tool, or by using 2 valid programmed keys.

To retrieve the factory keycode using 2 valid programmed keys, carry out the following steps within 10 seconds:

• Place the first valid programmed key into the ignition lock cylinder or backup starting location and turn the ignition on.
• Turn the ignition off and remove the first valid programmed key.
• Place the second valid programmed key into the ignition lock cylinder or backup location and turn the ignition on.

The factory keycode displays momentarily in the message center.
