As time went on and technology advanced and improved, automobile manufacturers began to combine physical and electronic protocols to stop theft. These key systems are known as transponder keys or chip keys, and they're designed to make it harder for thieves to start the vehicle.

The key chips inside the keys have a specific serial number, which transmits signals to the receiver in your car. When the signal is received it compares it with an existing code in the car's computer. If the codes are compatible, then the car will start. If the codes aren't compatible, your car will not even start. This is why you should keep an extra car key fob programmer near me especially if the system is transponder-based.

This energy is absorbed into the chip and sends back an audio frequency signal that contains an identification code that corresponds up to the unique serial number in the car's computer system. This prevents unauthorised attempts to start the car as only the correct key can perform the task.

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