Alarm System Transponder: Description and Operation
Description
DESCRIPTION
Each ignition key (2) used in the Sentry Key Remote Entry System (SKREES) has a transponder chip included on the circuit board (4) beneath the cover
(1) of the integral Remote Keyless Entry (RKE) transmitter (3). In addition to having to be cut to match the mechanical coding of the ignition lock
cylinder and programmed for operation of the RKE system, each new Sentry Key has a unique transponder identification code that is permanently
programmed into it by the manufacturer, and which must be programmed into the Sentry Key REmote Entry Module (SKREEM), sometimes referred to
as the Wireless Control Module (WCM), to be recognized by the SKREES as a valid key.
The Sentry Key transponder cannot be adjusted or repaired. If faulty or damaged, the entire key and RKE transmitter unit must be replaced.
