Why Get Your Car Key Programmed? Many people need their car keys programmed. If you have children who press the button too often or you've lost your keys then the remotes need reprogramming. Some auto locksmiths and dealerships have the tools needed to perform this task. They can also clone keys that are already in use, if that's possible. Transponder Keys A transponder key is a different term used to describe an electronic car key. It is sometimes referred to as chip keys or smart key. Transponder keys contain a microchip which can store and transmit data. This helps to ensure that your car is not stolen. The microchip transmits an unique identification code every time the key in the ignition is turned. When the ID code matches in your car's computers the immobilizer will be disabled and your engine will begin to operate. This is a more advanced security measure when compared to a non-transponder keys, which do have a chip, and is not compatible with the anti-theft systems of the majority of modern automobiles. Transponder chips were developed to decrease the number of car thefts. They have proven to be a huge success and the number of car thefts has decreased substantially since their introduction. When the key is put into an ignition an antenna that is small, called an inductive coil that is located on the car key's transponder will be powered up. The transponder then sends out a radio frequency signal containing a unique “password”. This is transmitted to the anti-theft system of your vehicle. If the password is correct, the car will disable its immobilizer and allow you to start the engine. If the password is not correct the immobilizer stays in effect and the engine will not start. This is a great way to prevent car thieves because even the case that a duplicate key could be made, the thief won't be able to fool your vehicle into starting.

Enhanced Security Transponder keys add an additional layer of security not always available with traditional key fobs.
