Before the turn of the 21st century the majority of cars had basic key systems. The keys themselves were metal with grooves that matched the internal parts of the ignition cylinder. As time went on and technology improved as it did, automobile manufacturers began to combine physical and electronic protocols to prevent theft. Key systems like these also known as transponder keys or chips keys are designed to make it difficult for thieves to start an automobile.

The key chips have an unique serial number that sends a message to the receiver in your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes match, then the car will start. If not, it will not start at all. This is why you should keep an extra car key, particularly if your system is transponder-based.

You'll require specialized equipment to be able to program keys. You'll need to buy an uncut key that matches your car model and make. You can buy them at an auto locksmith or a locksmith dealership, but it's important to buy the right one. If you use a key for another model, it won't work.

To begin the process, insert the new key into the ignition and turn it to the "on" position. You'll need to keep the key in this position for about 10 minutes and 30 seconds. Once the time is up, you can remove the key and check if the security light on your dashboard went out. If it didn't, you'll need to do it again for a third time.

The system can also detect lost or stolen cards and deactivate them. The newest models also allow remote management and configuration and are cloud-based.

Modern automobiles are equipped with keyless entry systems. The system works by sending radio signals which are received by a special keyfob. The signals are compared with the code that is stored in the computer of the car, and if all is in order the car will start to unlock. The car will not start when the signals aren't identical. There are a variety of steps you can take to program your new key fob, if it's not already programmed.

The chip absorbs the energy and then sends a radio frequency signal which contains an identification number. This code is in line with the unique digital serial numbers in the computer of the car. This will prevent any an unauthorized attempt to start the car, because only a valid key can start the car.

The technology is believed to be more secure than traditional keys for cars because it makes it harder for a thief to "hot wire" an automobile and start it. However, it's not foolproof and thieves have found ways to deceive and thwart the system so that even vehicles that have transponder keys aren't protected from theft.

Depending on the make and model of your vehicle depending on the make and model of your car, you might be capable of programming a new transponder key by yourself using a key programmer that's compatible with your specific car. The key programmer comes with a guide that will guide you step-by-step through the process. Once you have the key and key programmer, follow the directions carefully and ensure that the security light on your dashboard is turned ON before turning your engine on.

They will have the tools and equipment needed to cut a blank key, delete the old one from the computer of the car, and program the new key for it to work correctly. This will help you save money and time, and keep your car's safety system operating exactly as it should. It's also a lot safer than trying to do it yourself!

Key fobs are equipped with electronic chips that communicate via radio signals to the car's receiver. The car's computer then compares this key's code to the one stored in its database.
