1 General operation of the key
The Volvo SPA Tag ID has implemented a HF transmitter. It only works based on a bi-directional com-
munication when Keyless Entry & Start functionality is triggering via a LF Wake Up command issued by
the vehicles antennas and the Tag ID responds in HF. The Volvo Tag ID has no buttons and only is
available at vehicles with Keyless Entry & Start functionality.

available at vehicles with Keyless Entry & Start functionality.
With Keyless Entry or Start both Volvo Tag ID reacts on a LF Wake Up-Signal from the vehicle (initiated
after activating of the sensor of the vehicle, i.e. at sensor at the door handle or the Push Start Button,
which recognizes the wish to lock/ unlock the vehicle or to open the trunk or to start the vehicle) from the
vehicle and after that the Volvo SPA Tag ID responds in HF on the RKE frequency for autorization pur-
poses. When the authorization is successful the vehicle performs the desired action.
