How do you program a key
Before the turn of the 21st century the majority of cars utilized basic key systems. Keys were made of metal and incorporated grooves to match the internal components in the ignition cylinder. As technology improved, more and more automobile manufacturers began to combine physical and electronic protocols in order to prevent theft. These key systems are referred to as transponder keys or chip keys, and they're designed to make it difficult for thieves to open the vehicle.
The key chips inside the keys have a unique serial number that transmits a signal to the receiver inside your car. The signal is compared to the car's computer when it is received. If the codes match, then your car will begin to start. If the codes aren't compatible, your car won't even start. This is why you should keep an extra car key, especially if your system is transponder-based.
If you're looking to learn how to program keys, you'll need certain equipment. You'll need an uncut key that matches the car's model and make. You can buy them at an auto locksmith or a locksmith dealership, but it's essential to purchase the correct keys. If you attempt to use a key from an alternative model, it will not work.
Start the process by inserting the new key in the ignition and turning it "on". You'll need to keep the new key in this position for about 10 minutes and 30 seconds. When the time has passed you can take out the key and see if the security light on your dashboard went out. If not then you'll have to repeat the process for a third time.

The system is also able to detect stolen or lost cards and disable them. The most recent models also permit remote management and configuration, and are cloud-based.
Modern cars are equipped with keyless entry systems. To make this work the car emits radio signals which are picked up by a particular key fob. The signals are compared with the code that is stored in the car's computer, and if all is well the car will be able to unlock. If the signals do not match and the car does not start. If your key fob isn't already programmed, it is possible to follow a series of steps to program it.

When the key is inserted into the ignition lock barrel and then turned into the ON position the antenna ring emits an electromagnetic energy blast through the transponder chip. The chip absorbs the energy and then transmits a radiofrequency signal that includes an identification code. This code is in line with the unique digital serial numbers of the computer system of the car. This helps prevent unauthorised attempts to start the car, as only the correct key will be able to perform the task.
This technology is believed to be more secure than traditional keys for cars because it makes it much difficult for thieves to "hot wire" an automobile and get it started. It's not foolproof and thieves have discovered ways of tricking and defeating the system. So even cars with transponder key are not immune to theft.
