Transponder Keys
Transponder keys (also known as chip keys) include an electronic microchip embedded in the plastic head of your car key. When you insert the key into the ignition cylinder, it transmits a signal the computer system of your car via an antenna ring on the lock of the ignition cylinder. The chip in your car receives this signal and responds by generating an identification code. This proves that the key you're using is the correct one for your car. The car will not start without this response.
This is a relatively new form of anti-theft tech, but it has proven effective in stopping theft. Transponder chips are found in most modern cars.
The key that has the chip is typically thicker than a conventional flat metal key, and it will emit an electrical signal that is stronger when inserted into the cylinder. You can test the chip by wrapping the plastic part of your key in a few layers of tin foil before trying to start the engine. If it fails, the key probably has a transponder in it.
Most transponder keys also have batteries that supply the power required to operate the chip. However, this battery can be damaged over time, causing the chip to stop functioning. This can cause your key to not longer be able to activate the immobilizer or turn the ignition. If you own a transponder key, it is important to get the battery replaced as soon as possible.
Transponder chips are not as simple to duplicate as a simple mechanical key, which is why a new replacement can be expensive. It is recommended to visit the local locksmith instead of visiting the car dealership for this service. Local locksmiths have more tools and know-how to program a transponder key correctly for your car.
Certain transponder keys can be programmed on-board, but this process is generally more complex and requires a greater level of understanding of your specific vehicle's security system. You can try to do this yourself if you have the right equipment, however this is not recommended and could result in a corruption of the information on your car's chip.

They are more secure because the car must be within the range of a sensor in order to start the engine. This kind of key is also more difficult to duplicate, as it is laser cut on both sides. These keys are also known as "flip keys" or "transponder key". Some car brands have a similar cylindrical design, referred to as a Tibbe Key which is more difficult to duplicate.

Key Fobs
Since their introduction in the year 1990 Key fobs have become a standard feature of automobiles. These small devices do much more than just unlock doors and start a car and are also important theft deterrents. Key fobs connect with vehicles and perform different functions by using radio signals. When the button is pressed on the key fob it transmits a signal containing an unique code to a receiver located close to the locking system of the vehicle. The receiver reads this code and executes the requested action such as unlocking doors or launching the car. Some key fobs also control other functions, such as activating the car's panic alarm system, or disarming and arming the security system.
The radio frequency (RF) signals used by key fobs are akin to those utilized by cell phones. When the key fob is within the range of a receiver it transmits a small burst of energy that energizes copper coils that are located on both sides of the device. These coils convert energy from the radio into electricity, which powers the microcomputer inside the fob. The computer transmits a digitalized version of the unique ID number of your car which is later verified by the receiver.
A lot of newer cars are equipped with remote starter systems that allow the user to push a button on the fob to turn on the engine. In some instances, you'll have to insert an actual key into the ignition lock to start your vehicle. The majority of newer fobs come with a small key made of metal that is designed to function in the event that the RF system fails.
