How do you program the key
Up until the turn of the 21st century, the majority of cars had basic key systems. Keys were made from metal and featured grooves that correspond with the internal parts of the ignition cylinder. As time went on and technology improved, more and more automobile manufacturers began to combine physical and electronic protocols to prevent theft. These key systems are also referred to as transponder keys or chips keys, are designed to make it more difficult for thieves to start an automobile.
The key chips have an unique serial number which 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 the car will start. If the codes don't match, your vehicle won't start at all. This is the reason you should keep an extra car key especially if your system is based on transponders.
You'll require specialized equipment to be able to program keys. You'll also need an uncut key for your specific model and make. You can buy them at the locksmith shop or at a car dealership, but it's important to buy the right one. If you use a key from another model, it will not work.

Most modern cars are equipped with a keyless entry system. This system works by emitting radio signals which are detected by a special keyfob. The signals are compared with the code stored in the car's computer and if everything is well the car will be able to unlock. The car will not start if the signals are not identical. If your key fob isn't already programmed, it is possible to follow a series of steps to program it.

The chip absorbs the energy and then transmits a radio frequency signal which contains an identification number. This code matches the unique serial numbers in the car's computers. This stops any attempts by anyone else to start the car, as only correct keys will be able.
It is believed that this technology will be more secure than traditional keys for cars because it makes it much difficult for thieves to "hot wire" the vehicle and get it started.
