Keyless Entry Keypads

The keyless entry keypads are touch-sensitive capacitive sensors integrated into the front door window 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 over a LIN. 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 passive entry door lock touch sensors are integrated into the front door upper window mouldings and not replaced separately.
