• 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, have the system
serviced by your dealer.
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 a dealership. 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
• 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 dealer to have the spare key(s)
programmed.
Please read and understand the
entire procedure before you begin.
1. Insert the first previously
programmed coded key into the
ignition.
2. Turn the ignition from the 1
(LOCK) position to the 3 (RUN)
position. Keep the ignition in the 3
(RUN) position for at least three
seconds, but no more than 10
seconds.
