The car detects the signal and starts the engine only if the signal is in line with the one programmed into the vehicle. The vehicle is also programmed to stop when it detects an incompatible frequency. This makes it more difficult for novice car thefts to wire a vehicle hot and then turn it on.
The chip and the key are connected by the circuit board which includes an induction coil. When the key is placed in the ignition it creates an electromagnetic field around the transponder. This creates a signal that gets taken up by the coil, which sends it to the key's identification number. The ID number of the key is then sent back to the vehicle, and if it matches the engine will begin to run.

You can purchase these tools on the internet or at many locksmiths in the automotive industry. These tools aren't cheap but are essential for programming your car's chip.
