A vehicle includes an external keypad, having a touchpad. The keypad may be configured to identify an access code according to user input to the touchpad, the access code including one of (i) a numerical value indicating a count of simultaneously pressed keys of the touchpad, and (ii) a swipe pattern including a press, slide, and release from the touchpad; and send the access code to a controller to facilitate access to a vehicle unlock user interface. The controller may direct the keypad to display the vehicle unlock user interface on the keypad when the access code matches a predefined access code stored to the controller. The keypad may display a background logo when the keypad is available to receive user input and may display a vehicle unlock user interface on the touchpad when the access code is validated.
