As technology advanced the number of car makers began to combine electronic and physical protocols to avoid theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it more difficult for thieves to open the vehicle.

The key chips that are in the keys have a unique serial number that transmits an electronic signal 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 similar then your car will start. If not, it won't start at all.

The newest models also allow remote management and configuration and are cloud-based.

Modern cars come with keyless entry systems. This system works by emitting radio signals that are picked up using an specialized keyfob.

If your key fob is not already programmed, you may follow a few steps to program it.

The chip absorbs the energy and then transmits a radio frequency signal which contains an identification number. This code is in line with the unique serial numbers of the car's computers. This will prevent any unauthorised attempts to start the car as only the correct key can do so.

The technology is believed to be more secure than a conventional car key because it makes it difficult for a thief "hot wire" the vehicle and then start it. It's not foolproof, and thieves have discovered ways to trick and defeat the system. So even cars with transponder key are not protected from theft.
