2. Transponder coil and signal converter

The transponder coil reads the transponder code out of the transponder.

The signal converter obtains the transponder code from the signals sent by the transponder, and then sends this code on to the alarm system control module. With the help of the Porsche System Tester II 9588, the transponder of the key inserted in the ignition can be adapted to one of the four memory locations for transponders. The first time the transponder is adapted, its Secret Key is programmed. The Secret Key of the transponder can no longer be overwritten, i.e. a programmed and adapted transponder is permanently assigned to one vehicle.
