Transponder Keys
Transponder keys are typically used in newer cars. They feature an RFID microchip that sends a unique code for the car when keys are inserted into ignition. The idea behind this technology is to prevent theft by making sure that only the correct key can be used to start the car. Contact your local dealer or locksmith to see the demonstration of this new technology.
When the transponder is inserted in the ignition, the key transmits an information to the chip in the engine control unit (ECU) of the vehicle. The ECU is then able to determine whether the code contained in the key matches its digital serial number. If it does, then the ECU will release the immobilizer to allow the engine start. If the code is not in line to the code, then the ECU will deny the signal and prevent the engine from beginning.
The keys are more expensive than the traditional metal keys, but they provide greater security. However car thieves have changed to the changing times and have found ways around this security measure, so the extra cost is not enough to deter them entirely.

This means that as you push the button down it will move down a certain distance until it reaches an obstruction or triggers an internal spring. The switch will send a signal to start the car when the key is put into the ignition.
Intelligent keys contain chips that communicate with the computer system of the vehicle. When you lose your key it will need to be replaced with a new key that is programmed for the vehicle. This requires more advanced key technology, only available through a specialized automotive locksmith. It is more expensive than a typical key replacement at the dealership.
