GMC 2007 Savana Van Owner's Manual page 103

When a new vehicle is delivered, the dealer
provides the owner with a pair of identical keys
and a bar-coded tag.
This vehicle has one
double-sided key for the
ignition and door
locks. It will fit with
either side up.
The bar-coded tag has a code on it that tells your
dealer or a qualified locksmith how to make
extra keys. Keep this tag in a safe place. If you
lose your keys, you'll be able to have new
ones made easily using this tag.
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
GM Roadside Assistance Center. See Roadside
Assistance Program on page 424.
