7. Reinsert the emergency key until it locks
into place.
NOTE:
The key fob battery should only be replaced by
qualified technicians. If the battery requires
replacement, see an authorized dealer.
Programming And Requesting Additional
Key Fobs
Programming the key fob may be performed by
an authorized dealer.
NOTE:
Once a key fob is programmed to a vehicle, it
cannot be re-purposed and reprogrammed to
another vehicle.
Only key fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a key fob is
programmed to a vehicle, it cannot be
programmed to any other vehicle.
Duplication of key fobs may be performed at an
authorized dealer. This procedure consists of
programming a blank key fob to the vehicle
electronics. A blank key fob is one that has
never been programmed.
NOTE:
When having the Sentry Key Immobilizer
system serviced, bring all vehicle keys with
you to an authorized dealer.
Keys must be ordered to the correct key cut
to match the vehicle locks.
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 cannot reprogram a key
fob obtained from another vehicle.
WARNING!
The integrated key fob contains a coin cell
battery. Do not ingest the battery; there is a
chemical burn hazard. If the coin cell
battery is swallowed, it can cause severe
internal burns in just two hours and can
lead to death.
If you think a battery may have been swal-
lowed or placed inside any part of the body,
seek immediate medical attention.
Keep new and used batteries away from
children. If the battery compartment does
not close securely, stop using the product
and keep it away from children.
WARNING!
Always remove the key fobs from the
vehicle and lock all doors when leaving the
vehicle unattended.
Always remember to place the Keyless
Enter-N-Go Ignition in the OFF position.
