However, as time progressed and technology improved and improved, automobile manufacturers began blending physical and electronic protocols to protect against theft. These key systems are called transponder keys or chip keys and are designed to make it harder for thieves to open the vehicle.

The key chips have a unique serial code that transmits a message to the receiver inside your car. The signal is compared to an identifier in the computer of the car when it is received. If the codes match, your car will start. If the codes don’t match, your car won’t even start.

This prevents an unauthorized attempt to start the car since only the right key will be able to perform the task.

This technology is thought to be more secure than the traditional car key since it makes it more difficult for a criminal to “hot wire” the vehicle and start it.
