Up until the turn of the 21st century, the majority of cars utilized basic key systems. The keys themselves were metal with grooves that corresponded to the internal components of the ignition cylinder. As time passed and technology advanced as it did, automobile manufacturers began to combine electronic and physical protocols to protect against theft. Key systems like these also known as transponder keys or chips keys, are designed to make it harder for thieves to steal the vehicle.

The key chips have unique serial codes that transmits a message to the receiver inside your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes match, then the car will start. If the codes don't match, then your car will not even start. This is why you should keep an extra car key, especially if the system is transponder-based.

You'll require specialized equipment to learn to program keys. You'll also need a blank key for your specific model and make. They can be purchased from an auto dealership or from a locksmith but you must make sure they're the correct ones. If you attempt to use a key that is from another model, then it will not work.

The signals are compared to the code that is stored in the computer of the car and, if all is in order, the car key programing will unlock. The car will not start if the signals are not identical. There are a variety of steps you can take to program your new key fob if it isn't already programmed.

This prevents an unauthorized attempt to start the car because only a valid key will be able to perform the task.

This type of technology is thought to be more secure than the traditional car key, as it makes it harder for thieves to "hot wire" the vehicle to start it.

If the codes match the car starts. If the codes don't match the car won't start or remain dead. Most of these electronic key can be programmed and replaced by an experienced locksmith or auto dealer with the right equipment.
