How to program a Key

Up until the turn of the 21st century, most cars used basic key systems. The keys themselves were just metal and featured grooves that matched the internal components of the ignition cylinder. However, as time progressed and technology advanced, more and more automobile manufacturers began to combine electronic and physical protocols to protect against theft. These key systems, also known as transponder keys or chips keys, are designed to make it harder for thieves to start an automobile.

The key chips have unique serial codes that sends a message to the receiver inside your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are similar, your car will begin. If not, it won't start at all. This is one of the main reasons why you should always keep a spare key for your vehicle, particularly in the case of transponder-based systems.

The energy is absorbed by the chip and sends back an audio frequency signal that contains an identification code that corresponds with the unique digital serial number in the car's computer system. This prevents unauthorized attempts to start the car because only a valid key can do so.

The technology is believed to be more secure than a traditional car key because it makes it harder for thieves to "hot wire" the vehicle to start it.
