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௢ 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 no previously programmed coded keys are
available, you must take your vehicle to your
dealer to have the spare key(s) programmed.
1. Insert a previously
programmed coded key
into the ignition.
2. Turn the ignition
from the 3 (OFF)
position to the 4 (ON)
position. Keep the
ignition in the 4 (ON)
position for at least one second, but no more than
10 seconds.
3. Turn the ignition to the 3 (OFF) position, and
remove the coded key from the ignition.
4. Within ten seconds of removing the previously
programmed coded key, insert the other previously
programmed coded key into the ignition.
