The keys themselves were metal and had grooves that matched the internal components of the ignition cylinder. As technology improved the number of car makers began to combine physical and electronic protocols to avoid theft. These key systems are known as transponder keys or chip keys and are designed to make it harder for thieves to open the vehicle.

The key chips contain a unique serial code that sends a message 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 identical the car will begin to start. If the codes don't match, then your car will not even start.
