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 Radio Frequency (RF) receiver
to prevent unauthorized vehicle operation.
Therefore, only key fobs that are programmed
to the vehicle can be used to start and operate
the vehicle. The system will shut the engine off
in two seconds if an incorrect key fob is used to
start the engine.
After placing the ignition in 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.
