The master key is used for the ignition, as well as all door locks a d storage compartments. W e n a new vehicle is delivered, the deder removes the plugs from the keys, and gives them to the first owner. However, if the ignition key does not have a plug, there may be a bar-coded key tag instead. Each plug has a code on it that tells your dealer or a qualified locksmith how to make extra keys. Keep the plugs in a safe place. If you lose your keys, you'll be able to have new ones made easily using these plugs or the tag. If your ignition keys don't have plugs, go to your dealer for the correct key code if you need a new ignition key. The vdetkey is used for the ignition and the two side doors only. It will not open the trunk or glove box. This is a theft-deterrent feature. The vdet key should always be used when valetpuking your vehicle. 2-3
