The wife and other family members have done this with several vehicles, They just went to the dealer with the vin, and verification of ownership, picture I.D, and usually something with the vin and owners info on it. Just call the local dealer and ask. Also two of these vehicles had the chip in the key, but didn't mater just to unlock the door, however they would not start the vehicle. What ever you do just don't take a slim Jim and try pushing and pulling in the door to get it unlocked, if you can't get a key get someone that knows what they are doing. The wire thru the door rubber is the best thing next to a Key.
