Disclosed are systems and methods that uses a window as a keypad entry system that functions as a replacement for a keyless entry keypad in a vehicle. The system includes a vehicle window functional as a keypad using piezoelectric transducers that capture resonance from the vehicle window when pressure waves (e.g., generated by voice commands or taps) impact the glass. A transducer controller amplifies the vibrations from the vehicle window user tap or spoken commands and triangulates the signal to localize a position of the origination point of the tap, which may be mapped to a respective numeric or cardinal input value. The system may include a low power mode that receives input while the vehicle is off.
