Types of Ignition Key Replacement
The most basic type of car key is the blade style that you insert into an ignition lock cylinder in order to start your vehicle. These keys are commonly used in older vehicles, however the latest models come with transponder chips that need to be programmed into the car to work.
It is common to get these keys replaced at a dealership or an automotive locksmith. They can provide an replacement with your car's VIN number.
Transponder Keys
Transponder chips can be found in cars manufactured in the last 20 years. It's a combination of electronic and mechanical security. It works by sending an encrypted message to the vehicle when you insert the ignition key. The engine control unit compared the code against its internal database to determine if you are the owner of the vehicle who is authorized. If you are, the car will start. The process is completely invisible and takes milliseconds.
You will see a small chip on the front of your key, if you've got transponders. The easiest method to test it is to insert the key into the ignition and then turn it on. If your car responds to the keys, it means that it has been programmed and verified as a valid transponder.
This is because, while traditional keys work with lock tumblers to unlock the vehicle, transponder chips transmit an electronic signal directly to the computer. This helps prevent individuals from hot-wiring vehicles by ensuring that the correct key is used to activate the ignition system.
To reprogram a transponder key it is necessary to follow these simple steps. First, ensure the key is in good working state and put it away. Then, put the blank key in the ignition and turn it to the "on" position. After about 15 minutes, turn off the ignition. After that, you can try to start the car again. If it fails to start, then you will need to repeat the process of turning off and turning on the car.
The process of reprogramming transponder keys is more complicated and costly than making a duplicate of a standard mechanical car key. In addition, you'll require the key professionally cut and a car key programming device is required to extract the code from your ECM and then match it to a new transponder key.
Smart Keys Keys
With smart keys, a motorist can unlock their doors and start the engine by simply pressing a button without needing to insert the key into the ignition. The fob has an electronic transponder that connects to an immobilizer in the car, disarming it so the car can begin.
