Keys

The majority of modern vehicles require a transponder key in order to operate. This gives security and anti-theft protection.

Do you know whether the unit has been programmed to work with a different vehicle or if it could be reprogrammed?

If you want to program a new key the first step is to ensure that your vehicle is operating. Insert the key you want to program into the ignition, but do not turn it. You will only have a few seconds before the car's system resets the commands and then exits programming mode. Therefore, it is important to move fast and not pause between steps. To avoid this happening, turn off the engine. Change the key from "on" to "off" to test the system. The door locks should cycle, and you'll hear a chime to indicate that the process has been successful.

Transponder chips

Car keys that feature transponder chips need special programming to function. Any hardware store can give you an entirely new car key, but the real challenge lies in making it work with your car. The key has to be programmed to match the exact identification number on your vehicle, or else it won't start.

Transponder chips are a standard feature in modern cars and are designed to guard against car theft. The chip is a microcircuit that transmits a radio frequency signals when the key is put in the ignition. The car is able to detect the signal, and starts the engine only if the signal matches the original that was programmed into the vehicle. The car is also programmed so that it will shut down if it detects an invalid frequency. This makes it difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then start it.

The key and the chip are linked by the circuit board which includes an induction coil. When the key is put in the ignition the magnetic field is created around the transponder. This creates a signal which is taken up by the coil and sent to the key's identification. The ID number of the key is transmitted back to the vehicle and if it is in line with the engine will start.

To accomplish this, you'll need scanners or a computer with an USB port to read the chip and determine its identity.
