Security Threats

Passive Entry Passive Start (PEPS) system vehicles have several Low Frequency (LF) antenna transmitters that cover specific zones inside and outside of the vehicle. The LF antennas send beacon signals. If the smart key is within range (1 meter) of an antenna the 'sleeping' smart key picks up the LF signal. This signal wakes the smart key and triggers the processing of the received message. The smart key replies to the vehicle using a separate Radio Frequency (RF) channel. The RF channel frequency is:

• 433 MHz in Europe and Rest of World (ROW) markets.
• 315 MHz in North American Specification (NAS) and Japan markets.
