The Xpresskit CHWFR Wafer for Chrysler Smart Key Interface is an ignition interface for use with the 2008/2009 Chrysler Dodge and Jeep vehicles with the new style key and ignition barrel. This design utilizes a patent pending concept that does not require the installer to solder wires and installation only takes about 30 minutes. It is the first and only solution that maintains the integrity of the vehicle and does not void the vehicles warranty.
