Why Get Your Car Key Programmed? Many people need their car keys programmed. If you have children who press the button too many times or you've lost your keys then the remotes need reprogramming. Some auto locksmiths and dealerships have the equipment needed to complete this task. They can also copy an existing key, if that's possible. Transponder Keys A transponder key is another term used to describe an electronic car key, also often referred to as a chip key or a smart key. Transponder keys are equipped with an embedded microchip that can store and transmit information. This helps protect your vehicle from theft. The microchip transmits a unique identification code each when the key is turned in the ignition. When the ID code matches that in the car's computer the immobilizer is removed and the engine will begin to run. This is a more advanced security option than non-transponder keys, which do not contain an embedded chip and are not compatible with all modern anti-theft systems for cars. Transponder chips were created to cut down on car thefts. They have proven to be a huge success and the number of car thefts has decreased significantly since their introduction. When the key is inserted into the ignition, a small antenna called an inductive coil on the transponder of your car key will power up. The transponder will transmit the radio frequency signal along with a unique “password” to your vehicle's anti-theft system. If the password is correct the car will turn off the immobilizer, which allows you to start your vehicle. If the password isn't correct, the immobilizer will remain in place and the car will not start. This is an excellent way to prevent car theft since even if the key can be duplicated, thieves will not have access to the proper code to trick your car into getting started. The only drawback to a transponder key is that it isn't compatible with mechanical non-transponder keys.
