Lost original key truck in lock mode

You have a couple options. A local automotive locksmith can use the VIN and proof of ownership to cut you new keys that match the old ones and program them in as needed. Pricing varies a lot depending on the key and what needs to be done, local to me the average is about $60.00 for one key, $90.00 for two for a simple key. A dealer can also order you new keys using the same VIN and proof of ownership, however in most cases you need to get the vehicle to them while the locksmith will come to you. For them it can be $100.00 per key plus the tow charge. However it is best to call a few places to see what they charge.
