If you damage your key fob, locksmiths and electronic key fob services can help you get a less expensive replacement and can be programmed. According to Schlissel, a new smart key can set you back anywhere from a few hundred dollars to as much as $2000 for some high-end automobiles.
If you buy a new car, you'll most likely have to have the key fob and the vehicle programmed at the dealership, says Miles Johnson, Hyundai Motor America's Senior Manager, Quality, Service, and Technology Public Relations.
