SENTRY KEY REMOTE ENTRY
MODULE
DESCRIPTION
The Sentry Key Remote Entry Module (SKREEM)
(Fig. 2) performs the functions of the Sentry Key
Immobilizer Module (SKIM) and the Remote Keyless
Entry (RKE) module.
SENTRY KEY IMMOBILIZER
The
Sentry
Key
Immobilizer
System
(SKIS)
authenticates an electronically coded Transponder
Key placed into the ignition and sends a valid/invalid
key message to the Engine Control Module (ECM)
based upon the results. The “VALID/INVALID KEY”
message communication is performed using a rolling
code algorithm. A “VALID KEY” message must be
sent to the ECM within two seconds of ignition ON
to free the engine from immobilization. This Control-
ler Area Network (CAN) data bus message is sent to
the ECM after first going through the SKREEM. The
SKREEM is located behind the instrument cluster
and has a separately mounted antenna ring mounted
around the ignition cylinder (Fig. 3) which picks up
the transponder key signal.
