What is a transponder key?

A transponder car key is a key that has an anti-theft security feature included. This is achieved by incorporating an RFID microchip in the plastic head portion of the key. This chip will relay a signal to the immobilizer system of your car when the ignition is turned on. This prevents hot-wiring of the car and makes it extremely difficult to steal your vehicle.

However, this does not mean that transponder keys are infallible, because even though they add an extra layer of security, it does not mean that a criminal cannot use their skill set to gain entry into the vehicle. It simply means that it takes them longer and more effort to do it, which is why this security feature is a huge benefit for anyone who cares about the security of their vehicle.

The way the transponder key functions is very simple. The microchip in the plastic head of the transponder key is programmed with an individual serial number that is a match for the immobilizer in your vehicle. The immobilizer system will verify the serial number when you insert the key in the ignition. If it matches the number, the engine will start and if not it does, the car won't begin.

There are several types of transponder chip that can be programmed, and the type of chip your vehicle is using will determine which type of key you own. Professional locksmiths and search engines can help you find the correct transponder for your vehicle.

In general, transponder keys are more expensive to replace than non-transponder keys because they are more expensive due to the cost of the microchip. The dealership for your vehicle is the most expensive option for getting a replacement key since they have the highest overhead costs, but you can also contact an expert locksmith to obtain your new key.

Another important thing to be aware of is that you can only program the transponder key only if it has not been cut already. You can do it yourself if purchase a transponder from one of the stores that offer these services. However, you'll need a special tool to accomplish this job.
