How do you program the key
Up until the turn of the 21st century the majority of cars utilized basic key systems. Keys were made from metal and had grooves to match the internal components in the ignition cylinder. However, as time progressed and technology improved, more and more automobile manufacturers began to combine physical and electronic protocols to protect against theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it harder for thieves to get into the vehicle.
The key chips come with an unique serial number that sends a message to the receiver inside your car. When the signal is received it is compared to a code stored in the car's computer. If the codes are identical, your car will begin. If not, it will not start at all. This is one of the main reasons to keep a spare key in your vehicle, especially if you have a transponder-based system.

The signals are then compared against the correct code stored in the car's system, and if everything is in order the car will start to unlock. If the signals do not match then the car won't start. There are a variety of steps you can follow to program your new key fob if it's not programmed yet.

The chip absorbs the energy and then sends a radio frequency signal that contains an identification code. The code is matched to the unique digital serial numbers of the computer system of the car. This will prevent any unauthorised attempts to start the car, since only the right key will be able to perform the task.
This type of technology is thought to be more secure than the traditional car key since it makes it difficult for a thief "hot wire" the vehicle and then start it.
