Transponder Chips
If your car was built within the last 20 years, it is likely that it contains a transponder chip within of it. This is a little plastic piece in the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When it is activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then taken up by an antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the correct one for your particular car.
This is what prevents from modifying or hot-wiring the vehicle's ignition system to turn it on. The chip inside the key also proves that you are the legal owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular keys, but with a plastic top. The chip is contained within the plastic part of the keys. There are a variety of cuts: a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will be taken up by the chip, causing it to transmit a signal back to the car. If the computer onboard the car recognizes the signal as valid, it will disable vehicle immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as the right one, it will prevent the engine from starting and will alert you by flashing its lights and sounding an alarm. This feature is intended to discourage people from attempting to alter the vehicle, but it isn't a foolproof security measure. A determined and skilled thief can still get around this system by using a specific device that intercepts the signal.
You can see that a transponder is a great option. Every car owner must take this into consideration in order to safeguard their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making sound chirps to help locate a car in a parking lot Key fobs today can also switch on a heated steering wheel or roll down all of the windows with a single button click. These extra features could make it difficult to locate your car keys.
Key fobs communicate with one other and the car using radio frequencies that are transmitted by an antenna that is located in the middle of the key. The transmission is encrypted, which helps keep others from stealing and re-transmitting the signal.

Keyfobs can be programmed in different ways based on the make and model of your car. Some cars allow you to do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a new key fob, or an alternative one.
When you press a key fob's button the microchip inside sends an informational code to the car's receiver it is paired with. The receiver then compares this information with the 'allowed' signals inside the fob, and either locks or opens the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't permitted to operate.
When a car is connected with a specific fob, it will only accept signals from that device. As a result, other fobs won't work with the vehicle even though they have the same appearance. This ensures the security of the computer system of the car and prevents unauthorized key fobs gaining control of it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements supplied by the manufacturer. The reason for this is that the only place that has the knowledge to create a replacement fob is in the service department of a dealer. However, some aftermarket fobs -- usually those for older models with less sophisticated systems -- can be programmed by customers without the need of dealers.
