The majority of modern vehicles require a transponder keys to operate. This is a security feature and anti-theft protection.

Do you know whether the unit is programmed to work with another vehicle or if it could be programmed again?
If you are planning to program a new key the first step is to ensure that your vehicle is on and running. Insert the key you'd like to program into the ignition, but don't turn it. There are only a few seconds before the car's system resets commands and exits programming mode. It is important that you be quick and don't delay between each step.

Transponder chips, used to protect cars from theft are a standard feature of modern automobiles. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is inserted. The car is able to detect the signal and begins the engine only if the signal matches the one programmed in the vehicle. The vehicle is also programmed to shut down if it detects an invalid frequency. This makes it difficult for thieves who aren't experienced to wire a vehicle hot and then start it.
A circuit board that has an induction coil that connects the chip to the key. When the key is inserted into the ignition, it creates an electric field around the transponder. This generates a signal that is amplified by the coil which transmits it to the key's identification number. The key's identification code is returned to the car and the engine is started if the identification number matches.
