As programming car key passed and technology advanced as it did, automobile manufacturers began blending electronic and physical protocols to prevent theft. These key systems are referred to as transponder keys or chip keys and they're designed to make it difficult for thieves to open the vehicle.

The key chips in the keys have a unique serial number that sends a signal to the receiver in your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are similar the car will begin to begin to start. If the codes don't match, then your car won't even start.

The majority of modern cars are equipped with an entry system that is keyless. The system works by sending radio signals which are detected by the keyfob. The signals are compared with the code stored in the car's computer, and if all is in order the car will start to unlock. The car won't start if the signals are not the same. There are a variety of ways to program your new key fob if it's not already programmed.

The chip absorbs this energy and then transmits a radio frequency signal that includes an identification code. This code is in line with the unique serial numbers of the car's computers. This helps prevent unauthorised attempts to start the car, as only the correct key can perform the task.

The technology is believed to be more secure than conventional car keys because it makes it more difficult for thieves to "hot wire" the vehicle and start it.
