Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. It's the tiny plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then absorbed by the special antenna that is attached to the barrel that controls your ignition in your car. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the right one for your specific vehicle.
This is what stops from modifying or hot-wiring the ignition system of your vehicle to get it started. The chip inside the key also confirms that you are the legal owner of the vehicle. This can reduce car theft.
Regular transponder keys are designed like regular metal keys with an outer layer of plastic. The chip itself is housed inside the plastic portion of the key, and there are a few different types of cuts on these keys: a cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.
A circuit inside the induction coil will emit a signal when the transponder is placed in the an ignition barrel. The signal will be absorbed by the chip, causing it to send a signal back to the car. If the computer on the car detects this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to start.
If the car does not recognize the transponder signal as being the correct one, it will keep the engine from starting and will notify you by flashing its lights and sounding siren. This function is designed to discourage those who would attempt to alter the vehicle. However it isn't an unbreakable security measure. A determined and skilled thief can still get around this system by using a specific device that blocks the signal.
As you can see there are quite a number of benefits to having transponder keys. This is something that all car owners should consider if they want to safeguard their investment and minimize the chance of theft.

Key fobs are able to communicate with each with the car via radio frequencies that are transmitted via a small antenna located in the middle of the key. The signal is encrypted to block other key fobs from stealing or stealing the signal.
You can program a keyfob in different ways based on the make and model of your car key programmed. Some cars allow you to do this yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order to program a replacement key fob or an additional one.
When you press a key reprogramming fob's button the microchip inside sends a code to the car's receiver it is linked to. The receiver compares this information to the signals that are allowed on the fob and either opens or locks the door. If the data doesn't match an chirping sound is heard and the car isn't able to operate.
Once the car is paired with a specific fob, it will only receive signals from that specific device. Other fobs will not work with the car, despite the fact that they appear identical. This protects the integrity of the car's computer system and to prevent unauthorised key fobs from taking control of the vehicle.
Most newer car dealerships will only deal with cars that have original fobs or genuine replacements supplied by the manufacturer. This is because the only place that has the experience to design a replacement fob is in a dealer's service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
