Lost Keys My father-in-law lost the keys to his 1993 Camaro. Is there a way for him to bypass the security?

These cars have an antitheft system called VAT. The key have 15 different values. This means fifteen different resistant values. For those who still have your keys use an ohm meter and take a reading on that little black thing on the key near the finger grip; write that value down. Then match that value to the correct key numer 1-15; get that key and have it cut; it should work. Also the wires can go bad in the ignition lock and the system won't read the key and will cutout the starter and fuel pump for around 10-15 minutes then reset. To fix this is to either replace the lock and the two wires that go with it. You can  bypass the vats using the correct value resister and finding the two small wires under the dash coming from the steering column unplug it and stick each end of the resistor in the female side of the plug going into the dash area. For those who have lost their keys you will need allot of patance and get all fifteen value keys in resistors; try them one at a time until you get the right one. The wrong one will trigger the security system and you will have to wait 10-15 minutes for each reset before trying again. Then get a new ignition lock and same key number 1-15 according to the resistor value; cut it for the new lock and install. The only other way is to buy a new vats module they program one time only and tear the dash out of the car to get to it.
