What is the transponder key?
A transponder car key comes with a security feature to prevent theft built in. This is done by integrating a radio frequency identification microchip in the plastic head section of the key. This chip is used to transmit a signal to the immobilizer system of your vehicle during the initial ignition process. This chip stops hot-wiring, making it difficult to take an automobile.
This is not to say that transponder keys are infallible as although they provide an extra layer of security it does not mean that a criminal can no longer use their skill set to gain entry into vehicles. It takes a lot of time and effort for them to accomplish this and that's why it is a great security option for anyone who is concerned about their vehicle's safety.
Transponder keys are simple to use. The microchip that is inside the plastic head of the transponder key is programmed to hold an unique serial number that is linked to the immobilizer on your vehicle. The immobilizer system checks the serial number once you put the key in the ignition. If it is in fact the same the serial number, the engine will begin and if it doesn't, the car will not begin.
There are supplemental resources of transponder chips that can be programmed. The type of chip that your vehicle uses will determine the type of key you own. You can find the right transponder chip for your car through the search engine, or going to a professional locksmith and asking them what kind of key you have.
Transponder keys are more expensive to replace because of the microchip. The dealership that you use for your vehicle will be the most costly alternative for a replacement key due to the most expensive overhead costs, however you can also contact an expert locksmith to obtain your new key.
You can only program the transponder if haven't already cut it. You can try to do it yourself by purchasing a transponder chip from one of the many stores that provide these services, but you will need to have a special tool to complete this task.

You can also tell if your keys have chips by examining your ignition. If the key has a button to start instead of a hole then it probably has a chip.
