As technology improved, more and more automobile makers began to mix electronic and physical protocols in order to prevent theft. Key systems like these also known as transponder keys or chips keys, are designed to make it harder for thieves to open a vehicle.
The key chips come with unique serial codes that sends a message to the receiver in your car. The signal is compared to a code in the computer of the car when it is received. If the codes are similar then your car will start. If not, it will not start at all. This is why it is important to keep an extra car key especially if your system is transponder-based.

The system can also detect lost or stolen cards and then deactivate them. In addition, the newest models are cloud-based and permit remote management and configuration.
Modern automobiles are equipped with keyless entry systems. To make this work the car emits radio signals that are picked up by a particular key fob. The signals are compared with the code that is stored in the car's computer and if everything is in order, the car will unlock. If the signals do not match, the car will not start. There are several ways to program your new key fob, if it's not programmed yet.

The antenna ring transmits electromagnetic energy to the transponder whenever the key is placed into the barrel of the ignition lock. This energy is absorbed by the chip and it transmits the radio frequency signal, which includes an identification code that matches with the unique serial number in the car's computer system. This stops unauthorized attempts to begin the car as only the proper keys will be able to do so.
The technology is believed to be more secure than traditional car keys because it makes it harder for a thief to "hot wire" an automobile and get it started.

The key system was designed in a way to avoid hot-wiring which is using a key from an other vehicle to start your car's engine. This means that you'll need at least two working key fobs for your vehicle to ensure that the process works. This is just one of the reasons why it's best to have at least one spare key on hand.
Key fobs are equipped with electronic chips that transmit radio signals with the car's receiver. The car's computer then compares the key's code with the one stored in its database. If the codes are the same the car will be able to start. If the codes do not match the car won't start or will remain dead. Most electronic keys can be programmed and replaced by an experienced locksmith or auto dealer with the appropriate equipment.
If you can find an inexpensive car key programmer online or at an auto parts store, the process should be fairly straightforward.
