GMC 2005 Canyon Owner's Manual page 85

When a new vehicle is delivered, the dealer provides
the owner with a pair of identical keys and a key
code number.
There is one double-sided
key for the ignition, driver's
door lock, and tailgate.
The key code number tells your dealer or a qualified
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.
Notice: If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
If you ever do get locked out of your vehicle call the
GM Roadside Assistance Center. See Roadside
Assistance Program on page 7-6.
If your vehicle is equipped with the OnStar system with
an active subscription and you lock your keys inside
the vehicle, OnStar may be able to send a command to
unlock your vehicle. See OnStar
for more information.
