Transponder Keys
Transponder keys (also known as chip keys) contain an electronic micro-chip embedded within the head of your car key. When you insert the key into the ignition cylinder it sends a signal to the computer system of your car via an antenna ring located on the lock on the ignition cylinder. The chip inside your car is able to receive the signal and responds with an identification code confirming that the key is the right one for the vehicle. Without this confirmation the car will not begin to drive.
This is a relatively recent type of anti-theft technology but it has proven effective in preventing theft. Transponder chips can be found in all modern cars.
The key that has the chip is usually much larger than a standard flat metal key, and it will emit more electrical signals when inserted into the engine. You can test the chip by wrapping a few layers of thin aluminum foil over the plastic part of the key before trying to start the car. If the key doesn't work then it's probably a transponder.
The majority of transponder keys also have a battery to provide power to the chip. The battery could fail and cause the chip to stop functioning. If this happens your key will no longer operate the ignition or turn on the immobilizer in your car. It is crucial to replace the battery as soon as you can if have a transponder.

Switchblade Keys
Car keys of the past are no longer the simple metal objects they once were. Many key fobs now come with additional security measures that prevent unauthorized users from opening or locking your vehicle. Understanding how different types of car keys work helps you make informed decisions about key fob replacements or upgrades.

They are reasonably inexpensive to replace if you lose them, however they are less secure than modern ones.
In the early 1990s, automakers began using transponder key that communicates with a sensor in the ignition of the car. They are a more secure option since they require that the vehicle be within the range of the sensor for the engine to start. This type of key is also difficult to duplicate, as it is laser cut on both sides. These keys are commonly known as "flip key" or "transponder keys." Some car brands also use the same type of key with a cylindrical design that is known as a Tibbe key which is harder to replicate.
Most modern cars have a key fob that combines traditional car keys with a remote control. It appears like an ordinary key, with buttons that open doors, shut windows and to activate alarms. Some keys also have an electronic key that folds into the fob which resembles an actual switchblade. If you lose this kind of key, you'll have to go to the dealership to purchase a new one and have it electronically paired with your car.

Key Fobs
Key fobs have become a standard automobile feature since their introduction in the 1990s. These small devices are more than the ability to open doors and start the car. They also serve as a significant theft deterrent. Key fobs use radio signals to communicate with the vehicle and perform a variety of functions. When a button is pressed on the key fob it transmits a signal that contains a unique code to a receiver near the vehicle's locking system. The receiver interprets the code and then performs the action requested like unlocking the doors or starting the engine. Some key fobs can also be used to 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 similar to the signals used by cell phones. When the key fob is in the range of a receiver it transmits a small burst of energy that energizes copper coils on both sides of the device. The coils convert the energy of the RF into electricity, which powers the microcomputer inside the fob. The computer transmits a digital version of the unique ID number of your car, which is later verified by the receiver.
Many newer cars are equipped with remote starters that allow the user to press the button on a fob to start the engine. In some cases, however, you'll still require a key to insert into the ignition lock to turn on your vehicle. The majority of modern fobs come with small, metal keys that is designed to work in the event that the RF system fails.

This can be corrected by spraying dry oil-based lubricant into the cylinder (TeflonTM silicon, graphite or TeflonTM). Spray the lubricant in the cylinder, and then turn the key several times in both directions. The lock should be clear of any debris and be able to rotate with the key.
