Transponder Keys
Modern vehicles are fitted with transponder keys, also known as microchip keys. This technology is designed to stop car theft since it only allows the owner of the vehicle to begin it. These keys are more expensive than flat keys, but they provide a level of security that is well worth the price.
Transponder keys contain a small microchip that transmits a signal with an identification code that is unique when the key is within the range of an antenna. The receiver located near the ignition switch in your car receives the signal. The receiver and transmitter communicate to determine if the right code is in place. This is known as "hotwiring" and can be avoided by using transponder keys that emits a signal that has different serial numbers each time the key is inserted into the ignition.
The first transponder car keys were invented in the 1980s by General Motors, who developed the VATS system to fight increasing Corvette theft rates. Since then, the majority of major automakers have integrated the technology into their vehicles.
Typically, a transponder keys will appear exactly similar to a standard car key but with a plastic cover that houses the transponder. This kind of key is available in a variety of cuts, including a standard, laser, or sidewinder. Some transponder key have blades, while others are not bladeless.

Keys to VATS
Many GM automobiles come with VATS keys or Vehicle Anti Theft System. They can be a great security measure against theft of cars and function by sending a signal every time the key is turned. The signal is sent to the engine control module, which informs it that a working key is present. The module sets the ignition lock to only accept the correct key.
The signal is transmitted by two very small wires in the key. If the wires break, they can cause your vehicle to not start. You will usually be able to see that the security lamp will remain on or that you have to turn the ignition several times before it gets started.

Another possibility is that the ignition switch has been replaced by an uncompatible switch or using an aftermarket key. This is because keys with different codes may have a resistor that is different from the one being sent to engine control module.
An effective method to test your VATS module is to use an interrogator for VATS. It is a tool that reads the key and can be used by a dealer or locksmith. The tool also comes with an inbuilt VATS code calculator that will determine the resistance value of your key. You can also measure manually the key and determine the value of its resistance. This method is time-consuming because there are fifteen different resistance levels for keys.
There are two types of VATS keys: a 6-cut single side key and a 10 cut double-sided key. The only distinction is that keys with 6-cut edges have a smaller key bow or head than keys that are 10-cut. It is important to remember that the possibility of contamination of the leaf contacts as well as key pellets in the ignition lock cylinder could cause an unresponsive condition. Don't apply liquid lubricants to the key bow, or pellet. The best lubricant for the key cylinder is powdered graphite.
Key Fobs
The majority of people think of the term "key fob" as an electronic device that replaces traditional keys to unlock a vehicle, house or apartment. They utilize short-range radio transmitters/radio frequency identification (RFID) chip and antenna to communicate with a wireless receiver within the device they control. The receiver is able to adjust to the unique coded signal from the key fob, which is in line with the information contained in its RFID tag.
Key fobs are capable of doing more than just locking and unlocking doors. They can also be used for remote control of home automation systems such as Z-Wave.

Keyless Entry
Keyless entry works by using a transmitter which is controlled remotely in the key fob to open or start the vehicle. The transmission is based upon the signals generated by the fob, and is encrypted to prevent unauthorised access. Some keyless systems utilize rolling codes to secure the system that is essential for fleet vehicles.
