It isn't to say that transponder keys are infallible, because although they provide an additional layer of security, it does not mean that a criminal cannot use their skill set to break into the vehicle. It simply means that it takes much more time and effort to do so which is why this security feature is a huge benefit for anyone who cares about the security of their vehicles.
The way in which transponder keys function is quite simple. The microchip that is inside the head of the transponder key is programmed with a unique digital serial code that is a match for the immobilizer inside your vehicle. The immobilizer system checks the serial number once you insert the key in the ignition. If it is in fact the same, the engine will start and if not it does, the car won't start.

Certain keys have a transponder inside the key head, whereas others do not. If your key has a chip the bow cover (the plastic part at the top of the key) will be more thick than on a non-chip key. It is also possible to tell whether your key has a chip by looking at the ignition. If it has a push-to start button instead of a key hole, it's most likely one with chip.
The next step is to decide the method of programming to be employed. Some transponder key can be programmed with on-board diagnostics while others require a special key programming device. The key programming device has to be compatible with the particular transponder or circuit board key being used, and must also work at the same frequency as the vehicle's onboard computer.
