BACKGROUND

Vehicle users widely appreciate the ability to enter a vehicle using a keypad. They appreciate the convenience of leaving keys inside the vehicle or the ability to enable guests/children to access to the vehicle without giving them the keys.

Keypads are generally disposed on an exterior surface of the vehicle on the door or door pillar. Various types of button interfaces are currently used, which may be susceptible to weather conditions when configured outside of the vehicle. Other input mechanisms, including microphones, may also be utilized in automotive control systems to provide input for various applications associated with automotive operation. Conventional microphone sensors may also be susceptible to weather conditions when configured outside of a vehicle.

It is with respect to these and other considerations that the disclosure made herein is presented.
