SECURILOCKYPASSIVE ANTI-THEFT SYSTEM
The SecuriLockypassive anti-theft system provides
an advanced level of vehicle theft protection. Your
vehicle's engine can only be started with the two
special SecuriLockyelectronically coded keys
provided with your vehicle. Each time you start your
vehicle, the SecuriLockykey is read by the
SecuriLockypassive anti-theft system. If the
SecuriLockykey identification code matches the
code stored in the SecuriLockyanti-theft system,
the vehicle's engine is allowed to start. If the
SecuriLockykey identification code does not match
the code stored in the system or if a SecuriLocky
key is not detected (vehicle theft situation), the
vehicle's engine will not operate.
The SecuriLockypassive anti-theft system is not
compatible with aftermarket remote start systems.
Use of these systems may result in vehicle starting
problems and a loss of security protection. Large
metallic objects or devices such as the Mobil
Speedpassyon the same key ring as your
SecuriLockykey may cause vehicle starting
problems. These objects and devices cannot damage
the SecuriLockykey, but can cause a momentary
problem if they are too close to the key when
starting the engine. If a problem occurs. turn
ignition off and restart the engine with all other
objects on the key ring held away from the
SecuriLockyignition key.
Spare SecuriLockykeys can be purchased from
your dealership and programmed to your
SecuriLockypassive anti-theft system. Refer to
Programming spare SecuriLockykeysfor more
information.
If one or both of your SecuriLockykeys are lost or
stolen and you want to ensure the lost or stolen key
will not operate your vehicle, bring your vehicle and
all available SecuriLockykeys to your dealership for
reinitialization.

Theft indicator
The theft indicator on the instrument cluster will
operate as follows:
²When the ignition is OFF, the theft indicator will
flash briefly every 2 seconds to indicate the
SecuriLockysystem is protecting your vehicle.
²
When the ignition is turned to RUN or START, the
theft indicator will light for 3 seconds and then go
out. If the theft indicator stays on for an extended
period of time or flashes rapidly, have the system
serviced by your dealership or a qualified technician.
Programming spare SecuriLockYkeys
Spare SecuriLockykeys can be purchased from
your dealership and programmed to your
SecuriLockypassive anti-theft system (up to a total
of 8 keys). Your dealership can program your new
SecuriLockykey(s) to your vehicle or you can do it
yourself using the following simple procedure. To
program a new SecuriLockykey yourself, you will
need two previously programmed SecuriLockykeys
(keys that already operate your vehicle's engine). If
two previously programmed SecuriLockykeys are
not available (one or both of your original keys were
lost or stolen), you must bring your vehicle to your
dealership to have the spare SecuriLockykey(s)
programmed.
Procedure to program spare SecuriLockYkeys
to your vehicle
New SecuriLockykeys must have the correct
mechanical key cut for your vehicle.
Conventional (non-SecuriLocky) keyscannotbe
programmed to your vehicle.
You will need to have two previously programmed
SecuriLockykeys and the new unprogrammed
SecuriLockykey readily accessible for the
procedure. Please read and understand the entire
procedure before you begin.
