It is possible to reprogram your remote in the event that your children press the button too often or if you've lost keys. Some auto locksmiths and dealerships have the equipment needed to perform this task. They can also clone your existing key if it's possible. Transponder Keys A transponder keys is a different term used to describe an electronic car key, often referred to as a chip key or a smart key. Transponder keys contain a microchip that can store and transmit information, which can help prevent your vehicle from being stolen. The microchip sends out a unique identification code every when the key is inserted into the ignition. Once the ID code matches in the car's computer the immobilizer will be removed and the engine will begin to operate. This is a more advanced security measure when compared to a non-transponder key, which does not include a chip and is not compatible with the anti-theft system of most modern cars. Transponder chips are being implemented to help reduce thefts from cars. They have been hugely successful. 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 power up. The transponder will transmit the radio frequency signal along with an unique "password" to the vehicle's anti-theft device. If the password is valid, your car will deactivate the immobilizer and allow you to begin the vehicle. If the password is wrong the immobilizer will remain active and the engine won't begin. This is a great method to deter thieves from taking your car because even if a duplicate key can be made, the thief will not have the code to trick your vehicle into running. The only drawback to transponder keys is that it's not compatible with mechanical non-transponder keys. These kinds of keys for cars function by physically moving lock m
