SENTRY KEY
The Sentry Key Immobilizer System prevents unauthorized
operation of the vehicle by disabling the engine.
The system will shut the engine off after 2 seconds of
running if an invalid key is used to start the vehicle. This
system utilizes ignition keys which have an electronic
chip (transponder) embedded into them. Only keys that
have been programmed to the vehicle can be used to start
and operate the vehicle.
The Sentry Key Immobilizer System does not need to be
armed or activated. Operation of the system is automatic
regardless of whether or not the vehicle is locked or
unlocked. During normal operation, the Theft Alarm/
Immobilizer Light will come on for three (3) seconds
immediately after the ignition switch is turned on for a
bulb check. Afterwards, if the bulb remains on, this
indicates a problem with the electronics.
If the bulb begins to flash after the bulb check, this
indicates that an invalid key has been used to start the
vehicle. Both of these conditions will result in the engine
being shut off after two (2) seconds of running.
Keep in mind that a key which has not been programmed
is also considered an invalid key even if it is cut to fit the
ignition lock cylinder for that vehicle.
If the Theft Alarm/Immobilizer Light comes on during
normal vehicle operation (vehicle has been running for
longer than 10 seconds), a fault has been detected in the
electronics and the vehicle should be serviced as soon as
possible.
