What is a transponder?

A transponder key is a car key that has an anti-theft security measure integrated into it. This is accomplished by incorporating the radio frequency identification microchip into the plastic head portion of the key. This chip is used for relaying a signal to the vehicle's immobilizer during starting of the ignition. This stops hot-wiring the vehicle and makes it very difficult to steal your vehicle.

This is not to say that transponder keys are infallible as even though they provide an extra layer of security, it does not mean that a criminal cannot use their skill set to gain entry into the vehicle. It just means that it takes them much more time and effort to do so and that's why this security feature is a huge advantage to anyone that cares about the security of their vehicles.

The way in which a transponder key works is very simple. The microchip in the plastic head of the key is programmed with a unique serial number that is connected to the immobilizer system that is in your vehicle. The immobilizer system will verify the serial number when you insert the key in the ignition. If the serial number is in line, then the engine will begin.

There are several different types of transponder chip that can be programmed. The type of chip your vehicle is using will determine the type of key you own. Search engines and professional locksmiths can assist you in finding the right transponder to match your vehicle.

If your key is equipped with a chip, the bow cover (the plastic part that sits on top of the key) will be more thick than on a non-chip key. It is also possible to tell whether your key is equipped with chips by looking at your ignition. If the key has a button to start instead of a hole, it could be a chip.

Certain transponder keys can be programmed using onboard diagnostics, while others require a special key programming device. The device used to program keys must be compatible with the key transponder/circuitboard that is being utilized. It should also function at the same frequency of the computer on board of the vehicle.
