[QUOTE="FordTechOne, post: 1467381, member: 35543"] Two different methods of operation. Reference my earlier post in this thread: [URL]https://www.fordraptorforum.com/threads/keyfob-boosting-thefts.70381/page-9#post-1465761[/URL] [B]RKE[/B] The Remote Keyless Entry (RKE) feature incorporates the BCM and RTM. The RTM receives the Transmitter Identification Code (TIC) from the RKE, interprets the information, and sends a message to the BCM over a private LIN circuit as well as the CAN. If the BCM determines that the key is a valid programmed key, it carries out the requested command. [B] PATS[/B] When the BCM detects the START/STOP button is pressed, it begins the key initialization sequence by activating the PATS center antenna, the PATS rear antenna and both exterior door handle keyless entry antennas. Each antenna transmits a low frequency signal with an approximate range of 1 m (3 ft). The passive key activates if it is within range of the antennas. When the passive key activates, it sends the PATS identification code to the RTM via a high frequency signal. The RTM interprets the high frequency signal from the passive key and sends the information to the BCM over the LIN. In the case of PATS, the key needs to be activated by the antennas before it transmits the PATS ID code to the RTM. This prevents the key fob from constantly transmitting the PATS data when it is not near the vehicle. This guy tried it with equipment as you describe. He was only able to get access to the vehicle if 2 programmed key fobs were used in sequence, which is not a likely real-world scenario.
