Keyless Entry Keypad
The keyless entry keypads are touch-sensitive capacitive sensors integrated into the driver door upper moulding. When a finger touches the keypad, it changes the capacitance of the sensor in the area of the finger touch. The keypad determines which area is touched and communicates the number/button touched to the BCM. The keypad only works when touched with a finger. The keyless entry keypad may not work when gloves are worn. The gloves act as an insulator and do not allow the finger to change the sensor capacitance.
The keyless entry keypad touch sensor is integrated into the front door upper window mouldings and cannot be replaced separately.
