Lost your only car key? You don't need the original to get a replacement. A locksmith can cut and program a new key by using the vehicle's lock cylinder or, for modern cars, by accessing the car's onboard computer system. It takes a bit more work, but a skilled technician can create a fully functional key that starts and unlocks your car, often right on the spot.
