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. Please read and
understand the entire procedure before you begin.
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.
