Matching Transmitter(s) to
Your Vehicle
Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a transmitter is
lost or stolen, a replacement can be purchased through
your dealer/retailer. All transmitters need to be re-coded
to match the new transmitter. The lost transmitter will
no longer work after the new transmitters are re-coded.
The vehicle can have a maximum of eight transmitters
matched to it. See "Relearn Remote Key" under DIC
Operation and Displays (With DIC Buttons) on page 3-58
or DIC Operation and Displays (Without DIC Buttons)
on page 3-64 for instructions on how to match RKE
transmitters to your vehicle.
