How to Program a Key The majority of modern keys for vehicles need to be programmed before they will function.

The chip transmits a burst of energy back to the ignition lock, which it uses to determine if the key is correct to turn the car on. The car won't start with a key that isn't transponder-compatible, if it's been configured to only accept certain kinds of chips. This can prevent car theft since only the owner of the car can start the vehicle with a stolen key. There are ways to program keys without the transponder that was originally used. You will need to first purchase an uncut key that contains the appropriate chip for your car model. They are available at the majority of hardware and auto stores.
