Transponder Key

Each ignition key used in the SKIS has an integral transponder chip. Ignition keys with this feature can be readily identified by a Gray rubber cap molded onto the head of the key, while conventional ignition keys have a Black molded rubber cap, where it is molded within a plastic mount into the head of the metal key. In addition to being cut to match the mechanical coding of the ignition lock cylinder, each new sentry key has a unique transponder identification code permanently programmed into it by the manufacturer, The sentry key transponder cannot be adjusted or repaired. If faulty or damaged, the entire key must be replaced.
