As technology improved, more and more automobile manufacturers began to combine physical and electronic protocols to avoid theft. These key systems are referred to as transponder keys or chip keys and they're designed to make it difficult for thieves to start the vehicle.
The key chips contain an unique serial number which transmits a signal to the receiver in your car. When the signal is received it is compared to an existing code in the car's computer. If the codes are identical the car will begin to begin to start. If the codes don't match, your car won't even start.

This will prevent any an unauthorized attempt to start the car key programmers, because only a valid key will be able to do so.
The technology is believed to be more secure than traditional keys for cars because it makes it difficult for thieves to "hot wire" a vehicle and get it started.
