Transponder Chips
If your car was built in the last 20 years, then it contains a transponder chip within of it. It's a small plastic piece on the back of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is then taken up by the antenna that is positioned around the ignition barrel of your vehicle. This allows the computer in your vehicle system to determine if the transponder chip in 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 in the car key confirms that the owner is the one who is the owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys that are regular in shape like regular keys, but with a plastic top. The chip is located inside the plastic part of these keys. There are several different cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
The circuit in the induction coil will emit a signal when the transponder is placed in the an ignition barrel. The signal will be received by the chip, causing it to transmit a signal back to the car. If the onboard car computer recognizes this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and warn you with flashing lights and siren. This feature is intended to discourage people from trying to alter the vehicle, but it is not a foolproof security measure. A skilled and committed thief may still be able to bypass this system by using a special device to intercept the signal.
It is evident that a transponder is a great option. All car owners should consider this if they wish to protect their investment and decrease theft risk.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also turn on the car remotely, emit chirping sounds to aid in finding cars or turn on the heated steering wheel. These additional features can make it difficult to locate your car keys.
Key fobs communicate with each with the car via radio frequencies which are transmitted by an antenna in the middle of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.
Keyfobs can be programmed in a variety of ways depending on the make and model of your car. Some cars allow you to do this by yourself. However, the majority of newer models require you to visit a professional locksmith or dealer to program a new key fob, or an alternative one.
When you press a key fob's button it transmits an encoded code to the car's radio that it is paired with. The receiver compares this information with the 'allowed' signals inside the fob, and either locks or opens the door. If the data does not match the signals, the car will not be allowed to drive.
Once the car is paired with a specific fob, it will only accept signals from the device. Other fobs will not work with the car, even though they appear identical. This safeguards the integrity of the computer system that runs the vehicle and stops unauthorised key fobs from taking control of it.
Most dealerships with newer cars will only accept cars that have original fobs or genuine replacements supplied by the manufacturer. This is because the only place that has the expertise to prepare the replacement fob is the service department of a dealer. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by the consumer without the need for a dealership.
