You may need to re-program your remote if you have children who press the button too often or if you've lost your keys. Some dealerships and auto locksmiths have special equipment for this. They can also clone your existing key if it's possible. Transponder Keys A transponder key is another term used to describe an electronic car key, also often referred to as chip keys or smart key. Transponder keys contain microchips that store and send information, which can help keep your car from being stolen. The microchip transmits an unique identification code each time the key is inserted into the ignition. Once the ID code matches the code in your car's computer, the immobilizer will be turned off and your engine will start. This is a more sophisticated security method than non-transponder keys, which do not contain an embedded chip and are not compatible with the majority of modern anti-theft systems for cars. Transponder chips are being introduced to reduce car thefts. They have been an enormous success. When the key is put into an ignition, a small antenna called an inductive coil located on the transponder of your car key will turn on. The transponder then sends out the radio frequency signal which contains a unique "password". This is sent to the anti-theft system in your vehicle. If the password is correct, your car will shut down its immobilizer and allow you to start the engine. If the password is wrong, the immobilizer remains active and the engine will not start. This is a great way to prevent car thieves because even if a duplicate key can be created, the criminal won't have the code to fool your car into starting. The only downside to transponder keys is that it's not compatible with mechanical keys that are not transponder. They work by physically adjusting lock mechanisms on doors or the ignition cylinder.
