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 an RFID microchip inside the head of the key. This chip is used to relay a signal to your vehicle's immobilizer in the ignition's start-up procedure. This stops hot-wiring of the vehicle and makes it extremely difficult to take your vehicle.
This is not to say that transponder keys are secure, because although they provide an extra layer of security, it does not mean that criminals can no longer employ their skills to gain entry into a vehicle. It just means that it takes longer and more effort to accomplish this which is why this security feature is a huge benefit for anyone who cares about the safety of their vehicles.
Transponder keys are easy to use. The microchip inside the head of the transponder key is programmed to hold an individual serial number that corresponds with the immobilizer in your vehicle. When you put the key in the ignition the immobilizer will recognize the serial number and confirm it. If it matches the serial number, the engine will begin and if it doesn't the car will not start.
There are many different kinds of transponder chips that are able to be programmed. The type of chip your vehicle is using will determine the type of key you own. Professional locksmiths and search engines can help you find the right transponder to match your vehicle.
In general, transponder keys are more expensive to replace than non-transponder keys as they are more expensive due to the cost of the microchip. The dealership for your vehicle will be the most costly option for getting a replacement key because they have the highest overhead costs, but you can also seek out an expert locksmith to obtain your new key.
