Keyless Entry Keypad
The keyless entry keypad is integrated into the front door window molding. The BCM sends voltage signals on 3 separate circuits to the keyless entry keypad. When an individual keyless entry keypad button is touched, an individual or combination of the input circuits is routed to ground. Based on these inputs, the BCM determines which button was touched. When a valid code is received, the BCM locks/unlocks the doors.
When a button is touched, the buttons illuminate and turn off after 5 seconds have elapsed since the last button press. The keyless entry keypad also illuminates any time the illuminated entry feature is active.
The keyless entry keypad can be used for the following:
- Unlock the driver door
- Unlock all the doors
- Lock all the doors (except when the driver door is open)
- Program/erase up to 5 user codes
To provide added security, the Anti-Scan feature disables the keyless entry keypad for 1 minute after 36 button presses without a valid entry code being entered. The keyless entry 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. The Anti-Scan feature turns off after 1 minute of keyless entry keypad inactivity, the unlock button is pressed on a RKE transmitter, a passive entry feature is used, or the ignition is turned on.
To lock all doors, touch and hold 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. It is not necessary to enter the factory set or personal code prior to locking all doors.
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-stage unlock so that all of the doors unlock when a valid code is entered. Refer to: Staged Unlock Programming .
The factory keycode for the keyless entry keypad can be retrieved from a label on the BCM, using a diagnostic scan tool, or by using 2 programmed keys. To retrieve the factory keycode using 2 programmed keys:
- Place the first programmed key into the ignition lock cylinder or backup slot and turn the ignition on.
- Turn the ignition off and remove the first programmed key.
- Place the second programmed key into the ignition lock cylinder or backup slot and turn the ignition on. The factory keycode displays momentarily in the message center.
