Getting a new transponder key programmed for your car usually means a trip to the dealership or a locksmith, but some newer vehicles let you do it yourself with the right gear. The key contains a tiny chip that sends a unique code to the car's computer, and if they don't match up, the engine won't start. It's a quick process when you have the right equipment, but losing your only programmed key can be a hassle.
