Transponder Chips
If your car was manufactured within the past 20 years, then it has a transponder inside of it. It's the tiny plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your car.
When it is activated by an electro-magnetic field, the chip emits a low level signal. This signal is then taken up by the antenna that is fitted around the ignition barrel of your vehicle. This allows the car's computer system to determine if the transponder chip inside the key is the right one for your particular car.
This prevents the vehicle from starting by either hot-wiring or by altering the key. The chip in the key also proves that you are the legal owner of the vehicle. This will help reduce car theft.
Transponder keys appear like normal keys, but with caps made of plastic. The chip is contained within the plastic part of these keys. There are a variety of cuts: a standard cut, laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.
The circuit in the induction coil emits signals when the transponder is placed in the the ignition barrel. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the car's computer detects this signal as the correct one, it will shut down the vehicle's immobilizer and allow the engine to begin.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine and notify you via flashing lights and siren. This feature is designed to deter people from trying to hack into the vehicle, however it's not a 100% security measure. A skilled and determined criminal could still be able to bypass this system by employing a device designed to take over the signal.
As you can see, there are quite a number of advantages to having a transponder key. This is something that all vehicle owners should consider if want to protect their investment and decrease the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start your vehicle from a distance, make chirping sounds to aid in finding the car or switch on the heated steering wheel. A lot of these features might seem useful but they could make it harder for you to keep track of your car keys.
Key fobs communicate with one other and the car using radio frequencies which are transmitted by an antenna that is located in the center of the key. This communication is encrypted, which helps keep others from stealing and replicating the signal.
You can program a keyfob in various ways based on the model and make of your car. Some cars allow you to do this by yourself. However, most newer 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 inside the car with which it is linked. The receiver then compares the data with the permitted signals stored in the key fob, and then locks or opens the car's door. If the data doesn't match, a chirping sound is heard and the car isn't able to operate.
Once the car is paired with a particular fob, it will only receive signals from that device. Other fobs won't work with the car, despite the fact that they appear like. This is to safeguard the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements supplied 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's service department. Certain aftermarket fobs, typically ones for older models that have less sophisticated systems, can be programmed without the need for a dealer.
