Automatic arming
The vehicle is armed immediately after switching the ignition to the
accessory position.
The theft indicator will flash every two seconds when the vehicle is
armed.
Automatic disarming
Switching the ignition to the on position with a coded key disarms the
vehicle.
• The theft indicator will illuminate for three seconds and then go out.
• If the theft indicator stays on for an extended period of time or
flashes rapidly, contact your authorized dealer as soon as possible.
Replacement keys
If your keys are lost or stolen and you don't have an extra coded key,
you will need to have your vehicle towed to an authorized dealer. The
key codes need to be erased from your vehicle and new coded keys will
need to be programmed.
Replacing coded keys can be very costly. Store an extra programmed key
away from the vehicle in a safe place to help prevent any
inconveniences. Please visit an authorized dealer to purchase additional
spare or replacement keys.
Programming spare keys
You can program your own coded keys to your vehicle.
Tips:
• A maximum of eight keys can be coded to your vehicle.
• Only use SecuriLock keys.
• You must have two previously programmed coded keys (keys that
already operate your vehicle's engine) and the new unprogrammed
key(s) readily accessible.
• If two previously programmed coded keys are not available, you must
take your vehicle to your authorized dealer to have the spare key(s)
programmed.
