Abstract
A keypad having a plurality of switches identifies a numerical value according to user input to the plurality of switches. The numerical value may be computed as a total count of the plurality of switches that are swiped across in a consistent direction or may be computed as a total count of the plurality of switches that are simultaneously pressed. The keypad may further send the numerical value to a controller configured to facilitate access to vehicle unlock functionality.
