key for the ignition, driver’s
door lock, and tailgate.
When a new vehicle is delivered, the dealer provides
the owner with a pair of identical keys and a key
code number.The key code number tells your dealer or a quali ed
locksmith how to make extra keys. Keep this number in
a safe place. If you lose your keys, you will be able
to have new ones made easily using this number.
Your dealer should also have this number.

door hinges, latches and locks (including glove box
and console doors), hood latch assembly, secondary
