However, I'm assuming you have an ignition key. Look at the attached pdf file to identify the type of key you have. If it's a master key and it won't open the trunk, then drilling the hole will probably be necessary. If you have a valet key, you should contact your dealer with vin and proof of ownership and let them order you a master key which will also open the trunk. If the locks have been changed, the new key won't work however.
