DESCRIPTION
The Sen try Key Remot e En try Module (SKREEM)
(Fig. 2) performs the fun ction s of t he Sent ry Key
Im mobilizer Modu le (SKIM) and the Remote Keyless
Entry (RKE ) module.
SENTRY KEY IMMOBILIZER
The Sentr y Key Immobilizer System (SKIS)
authenticates an electronically coded Transponder
Key pla ced into the ignition a nd sen ds a va lid/in valid
key messa ge to the Engine Con trol Module (ECM)
based upon the result s. The “VALID/INVALID KE Y”
message communication is per formed using a r olling
code algorithm . A “VALID KE Y” message must be
sent to the E CM with in two seconds of ign ition ON
to free t he engine fr om immobiliza tion . This Con trol-
ler Area Net work (CAN) data bus message is sent to
the E CM after first going t hrough the SKREEM. The
SKREEM is located behind th e instrument cluster
and has a separ ately mounted ant enna ring moun ted
around th e ignition cylin der (Fig. 3) wh ich picks up
