The VATS Key Reader from Kaba Ilco enables you to identify the GM patented PASS automotive security system keys. The reader displays the correct resistor value, allowing you to quickly select the proper key for duplication. More than 200 model years of popular vehicles require VATS keys, including Buick, Cadillac, Chevrolet, Oldsmobile and Pontiac. Keys can be duplicated on a standard key machine, and the reader included in the VATS Kit displays the correct resistor value, allowing the key to be cut properly the first time. The complete kit contains one each of 15 single-sided keys; one each of 14 double-sided keys, along with a reader, foam organizer and carrying case.
