Systems amd methods for accessing a vehicle using a single, exterior control

An access system for a vehicle, comprising:

• a first vehicle subsystem configured to control access to an interior compartment of the vehicle;
• an actuator mounted on the vehicle and movable between first and second positions;
• and
• a controller coupled to the actuator and configured to:
• detect a first actuation sequence of the actuator, the first actuation sequence corresponding to an access code;
• during the first actuation sequence of the actuator, provide an audible, visual, or tactile response from the vehicle, by causing activation of a vehicle system that is optionally selected from one or more of an interior chime, a horn, a door lock motor, a mirror motor, a turn indicator, an alarm status indicator, a parking lamp, and a dome lamp;
• compare the access code to an authorization code;
• generate a first control signal configured to cause the first vehicle subsystem to switch between a first state and a second state when the access code corresponds to the authorization code;
• the access system further comprising a display system that is positioned inside of the vehicle but visible from outside of the vehicle, wherein the display system displays at least a portion of the access code during the first actuation sequence;
• and
• wherein the first vehicle subsystem is a door lock subsystem, wherein the first state is a locked vehicle state, and wherein the second state is an unlocked vehicle state.
