Automatic disarming

Switching the ignition to the 3 (ON) position with a coded key disarms
the vehicle.

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

A maximum of eight keys can be coded to your vehicle. Only
SecuriLock keys can be used. To program a coded key yourself, you
will need two previously programmed coded keys (keys that already
operate your vehicle's engine) and the new unprogrammed key(s) readily
accessible for timely implementation of each step in the procedure.
If two previously programmed coded keys are not available, you must
bring your vehicle to your dealership to have the spare coded key(s)
programmed.
Please read and understand the entire procedure before you begin.
