A transceiver is configured to: pair with a mobile device; and transmit a predetermined signal from an antenna to the mobile device. A zone module is configured to: receive a signal from the mobile device in response to the predetermined signal; and based on the signal, select a zone within which the mobile device is present from a group consisting of: a first zone that is defined by a first radius from the antenna; a second zone that excludes the first zone and that is defined by a second radius from the antenna, where the second radius is greater than the first radius; and a third zone that is radially outward of the second zone and that excludes the first and second zones.

Systems and methods for determining device location for passive entry and vehicle startup

An access system for a vehicle includes 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; compare the access code to an authorization code; and 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.
