Transponder Chips
Transponder chips are likely to be found in vehicles manufactured within the past 20 years. It's the small piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your car.
When activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then absorbed by the special antenna that is fitted around the barrel that controls your ignition in your car. The computer system of the vehicle is then able to verify that the key's transponder chip is the right one for your vehicle.
This prevents the vehicle from being started by hot-wiring or manipulating. The chip in the car key ensures that the owner is the person who owns the vehicle. key programmers will help reduce car theft.
Transponder keys appear like normal keys but they have caps made of plastic. The chip is located inside the plastic part of the keys. There are various cuts: a standard cut, laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
The circuit in the induction coil emits an electrical signal when the transponder is put into an ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the car's computer recognizes this signal as being the right one, it will disable the vehicle immobilizer and allow the engine to start.
If the car isn't able to recognize the transponder as being the proper signal, it will not start the engine and warn you with flashing lights and siren. This feature is designed to discourage people from tampering with the vehicle. However it isn't an absolute security measure. A determined and skilled thief can still get around this system with a specially designed device that blocks the signal.

These extra features can make it difficult to find your car keys.
Key fobs communicate with each other and with the car through radio frequencies that are transmitted through an antenna that is located in the middle of the key. The communication is encrypted, which helps to stop others from stealing and retransmitting the signal.
There are several ways to program a key fob depending on the make and model. Some cars allow you to do this by yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob or additional one.
When you hit the button on a key fob, the microchip inside transmits an informational code to the car's radio that it is paired with. The receiver then compares this information to the 'allowed' signals inside the fob, and either locks or opens the door. If the information doesn't match, the car will not be allowed to run.
Once the car is paired with a specific fob it will only accept signals from that specific device. This means that other fobs will not work with the vehicle even though they look the same. This protects the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. This is because the process of creating a replacement fob requires technological and security skills that can only be found in the dealer service department. Some fobs from the aftermarket, especially those from older models that have less advanced systems can be programmed with out the need for a dealership.
