They come with diagnostic software that enables them to communicate with the computer as well as bidirectional interfaces to work with the immobilizer system.

Transponder Chips
Transponder chips are likely to be found in cars that were manufactured in the last 20 years. This is a little plastic thing in the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is positioned around the ignition barrel of your car. The computer system in the vehicle will then confirm that the chip in the key's transponder is the right one for your vehicle.
This is what prevents doing hot-wiring or altering the ignition system of the vehicle to start it. The chip in the key also verifies that you are the legal owner of the vehicle. This can help to reduce car theft.
Transponder keys appear like regular metal keys but they have caps made of plastic. The chip is housed within the plastic part of the key and there are different types of cuts on the keys: a standard cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal will then get received by the chip, causing it to transmit a signal back to the car. If the computer inside the car detects the signal as correct it will turn off the car immobilizer to allow the engine start.
If the car doesn't recognize the transponder as the correct signal, it will not start the engine and warn you with flashing lights and a siren. This feature is intended to discourage people from trying to hack into the vehicle, but it's not a 100% security measure. A skilled and determined criminal might be able escape this security system by using a special device to take over the signal.
As you can see there are quite few advantages to getting transponder keys. This is something that all car owners should consider if they want to safeguard their investment and decrease the chance of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start the car remotely, emit chirping sounds to help locate a car or turn on the heated steering wheel. Many of these extra features may appear convenient but they could make it difficult for you to keep the keys to your car.
Key fobs communicate with each with the car via radio frequencies that are transmitted by an antenna that is located in the middle of the key. This communication is encrypted, which helps to keep others from stealing and retransmitting the signal.
There are a few different ways to program a key fob, based on the vehicle's model and make. Certain cars let you do this yourself. However, most newer models require you to visit a professional locksmith or dealer to program a replacement key fob or additional one.
When you press a key fob's button the microchip inside sends a code to the car's receiver that it is paired with. The receiver compares the information with the 'allowed signals' stored on the key fob and then locks or opens the car's doors. If the information doesn't match an chirping sound is heard and the car isn't allowed to function.
Once the car is associated with a particular fob, it will only accept signals from the device. In turn, other fobs won't work with the vehicle, even though they have the same appearance. This protects the integrity of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control over it.
Most newer car dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is because the only place with the experience to design the replacement fob is the service department of a dealer. Some aftermarket fobs, usually ones for older models with less sophisticated systems can be programmed without the need for a dealership.
