Tips

The working principle of the Porsche smart key is as follows:

The smart key can be divided into two parts: the entry system and the starting system. However, most keyless entry systems include a start function, and only a few models have entry functions. The smart entry system uses state-of-the-art RFID (Radio Frequency Identification) technology. RFID radio frequency identification is a non-contact automatic identification technology that automatically identifies target objects and obtains relevant data through radio frequency signals.

When the owner approaches the vehicle a certain distance, the door locks will automatically open and release the anti-theft function; when the owner leaves the vehicle, the door locks will automatically lock and enter the anti-theft state. However, in order to prevent the car owner from entering the car when the smart card is damaged or out of power, the keyhole is still retained on the door handle.
