Description and Operation

The Key Card system is a method of vehicle access that utilizes Near Field Communication (NFC) technology to verify the correct key is presented to the vehicle. Upon presentation, the vehicle will either lock or unlock as well as allow vehicle starting within a 2 minute time limit from when the card was first presented. A user would present their Key Card to the K300 Near Field Communication Backup Module, which is typically located behind an applique. For specific K300 location, a user may refer to the Owner's Manual, or the location is depicted on the Key Card itself. When a user presents a Key Card to the specified applique, the K183 UHF Short Range Low Energy Remote Control Access Transceiver will begin authenticating the Key Card via K300 as a pass-through component. If the information sent to the K183 UHF Short Range Low Energy Remote Control Access Transceiver matches the information stored in the K9 Body Control Module, vehicle access and power moding will be allowed. To power mode the vehicle while using Key Card, a user must do so within 2 minutes of tapping the Key Card to the specified applique.

Unlike the Digital Key system that utilizes the user's mobile device, Key Card is a standalone system that only shares the K183 UHF Short Range Low Energy Remote Control Access Transceiver as a control module. A Key Card must be learned to the vehicle prior to being used. This procedure can be accessed through Techline Connect. One card may be learned to more than one vehicle, and one vehicle has the capability of learning up to 8 Key Cards.

The Key Card system uses the following components:

• Key Card
• K183 UHF Short Range Low Energy Remote Control Access Transceiver
• K300 Near Field Communication Backup Module
