Keyless Entry Keypad: Notes

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).

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.

NOTE: The code displayed on the scan tool is from the RFA module. If it does not match the code on the BCM label, reset the keyless entry keypad code. Refer to REMOTE FUNCTION ACTUATOR (RFA) MODULE KEYLESS ENTRY KEYPAD CODE RESET in KEYLESS ENTRY KEYPAD CODE PROGRAMMING .
