SENTRY KEY
The Sentry Key Immobilizer system prevents unauthorized
vehicle operation by disabling the engine. The system does
not need to be armed or activated. Operation is automatic,
regardless of whether the vehicle is locked or unlocked.
The system uses a key fob, keyless push button ignition
and a RF receiver to prevent unauthorized vehicle opera-
tion. Therefore, only key fobs that are programmed to the
vehicle can be used to start and operate the vehicle. The
system will not allow the engine to crank if an invalid key
fob is used to start and operate the vehicle. The system will
shut the engine off in two seconds if an invalid key fob is
used to start the engine.
After turning the ignition switch to the ON/RUN position,
the vehicle security light will turn on for three seconds for
a bulb check. If the light remains on after the bulb check, it
indicates that there is a problem with the electronics. In
addition, if the light begins to flash after the bulb check, it
indicates that someone used an invalid key fob to start the
engine. Either of these conditions will result in the engine
being shut off after two seconds.
