How to Program a Car Key

How do you program the key

Before the turn of the 21st century the majority of cars utilized basic key systems. Keys themselves were metal and had grooves that were connected to the internal parts of 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 called transponder keys or chip keys and are designed to make it harder for thieves to open the vehicle.

The key chips contain unique serial codes that transmits 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 start. If not, it won't start at all. This is one of the primary reasons why you should always keep a spare key for your car, especially if you have transponder-based systems.

The chip absorbs the energy and then transmits a radio frequency signal that contains an identification code. This code matches the unique digital serial numbers of the computer system of the car. This is to prevent any attempts by anyone else to start the car since only right keys can be used.

This technology is thought to be more secure than a traditional car key since it makes it harder for thieves to "hot wire" the vehicle and start it.
