Methods and systems for detection of removable vehicle seats may be used to indicate presence or absence of a child in the vehicle. In some examples, an alarm system includes a radio frequency (RF) transceiver and a removable seat magnetic coupling. Various actions are triggered when the parent (e.g., guardian) goes beyond a predefined range while the removable seat is within the vehicle, such as sounding an alarm on a mobile electronic device. 1a magnet attached to a removable object;a magnetic sensor attached to a base, the magnetic sensor configured to generate a magnetic proximity signal representative of a magnetic proximity between the removable object and the base, the removable object configured to be removably attached to the base;a radio frequency (RF) circuit, the RF circuit configured to communicate with a mobile electronic device and to generate an RF proximity indication, the RF proximity indication representative of a device distance between the RF circuit and the mobile electronic device; and receive the magnetic proximity signal from the magnetic sensor;', 'determine, based on the magnetic proximity signal, that the removable object is attached to the base;', 'receive the RF proximity indication from the RF circuit;', 'determine, based on the RF proximity indication, that the device distance exceeds a maximum device distance threshold; and', 'generate an abandonment alert, the alert indicating that the removable object is attached to the base and that the device distance exceeds the maximum device distance threshold., 'a device processor electrically coupled to the magnetic sensor and to the RF circuit, the device processor specifically programmed to. A removable object proximity detection system, the system comprising: This application is a continuation of U.S. patent application Ser. No. 15/381,461, filed Dec. 16, 2016, which is a continuation of U.S. patent application Ser. No. 14/790,953, filed Jul. 2, 2015, now U.S. Pat. No. 9,550,454, both of ...
