As time passed and technology improved as it did, car manufacturers began blending physical and electronic protocols to protect against theft. These key systems are known as transponder keys or chip keys, and are designed to make it harder for thieves to get into the vehicle.
The key chips have an unique serial number which transmits a signal to the receiver in your car. The signal is compared to an identifier in the computer of the car when it is received. If the codes are identical the car will begin to start. If the codes don't match, then your vehicle won't start at all. This is one of the main reasons to keep a spare key for your car, especially when you use transponder-based systems.

This will prevent any an unauthorized attempt to start the car, since only the right key will be able to perform the task.
This technology is believed to be more secure than traditional keys for cars because it makes it much harder for a thief to "hot wire" the vehicle and start it.
