Transponder Chips

When it is activated by an electro-magnetic field the chip emits a low-frequency signal. This signal is then received by a specific antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to verify that the transponder chip inside the key is the right one for your specific vehicle.
This prevents the vehicle from being started by hot-wiring or manipulating. The chip in the key also confirms that you are the genuine owner of the vehicle. This will help reduce car theft.
Transponder keys appear like regular keys made of metal, but with caps made of plastic. The chip itself is housed within the plastic part of the key, and there are a few different cuts that can be found on the keys: a standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as being the correct one, it will disable the immobilizer on the vehicle and allow the engine to start.
If the car doesn't recognize the transponder as being the proper signal, it will not start the engine and will notify you via flashing lights and a siren. This feature is designed to discourage people from trying to tamper with the vehicle, however it is not a foolproof security measure. A determined and skilled thief can still get around this system using a special device that detects the signal.

Key Fobs

These extra features could make it difficult to find your car keys.
Key fobs utilize radio frequencies to connect with one another and the car. These frequencies are sent through a small antenna located inside the middle of the key. The transmission is encrypted, which helps to stop others from stealing and replicating the signal.
There are several ways to program a key fob, based on the vehicle's make and model. Some cars allow you to do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a replacement key fob or additional one.
When you press the button on a key fob the microchip transmits signals to the receiver in the car with which it is paired. The receiver compares this information with the 'allowed' signals stored inside the fob, and either opens or closes the door. If the data does not match, the car will not be allowed to run.
Once the car is linked with a specific fob, it will only accept signals from the device that is associated with it. This means that 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 prevents the use of unauthorized key fobs to gain control of it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security knowledge which can only be obtained in the dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by consumers without the need for an authorized dealer.
