Transponder Chips
If your car was manufactured in the last 20 years, chances are it contains a transponder chip within 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 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 car. The computer system in the vehicle will then confirm that the chip in the key's transponder is the correct one for your car.
This stops the vehicle from being started through hot-wiring or tampering. The chip in the key also confirms that you are the legal owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys appear like regular metal keys but they have caps made of plastic. The chip itself is housed within the plastic part of the key and there are different cuts that can be found on the keys: a cut laser cut (also called a sidewinder key) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal will be absorbed by the chip, causing it to send a signal back to the car. If the computer in the car is able to recognize the signal as valid, it will disable vehicle immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as being the correct one, it will stop the engine from starting and will alert you by flashing its lights and sounding siren. This is designed to deter people from trying to hack into the vehicle, but it's not a 100% security measure. A determined and skilled thief could still bypass this system using a special device that detects the signal.
As you can see, there are quite a number of benefits to having a transponder key. Every car owner must take this into consideration in order to safeguard their investment and minimize the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making sound chirps to help locate a car in a parking lot Key fobs today can also turn on a heated steering wheel or open all windows with a single button push. A lot of these features might seem useful but they could make it more difficult to keep the keys to your car.
Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are transmitted through a small antenna located in the middle of the key. The signal is encrypted to stop others from stealing or modifying the signal.
Keyfobs can be programmed in various ways based on the make and model of your car. You may be able to do it yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or an additional fob.
When you press the button on a key fob, the microchip sends an indication to the receiver inside the car that it is paired. The receiver then compares the data with the 'allowed signals' stored in the key fob and then opens or locks the car's doors. If the information doesn't match an chirping sound is heard and the car isn't permitted to function.
Once the car is paired with a specific fob it will only receive signals from that device. Other fobs won't work with the car, even if they look like. This is to safeguard the integrity of the car's computer system and prevent unauthorised key fobs from taking control of the vehicle.
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 due to the fact that preparing an appropriate replacement fob requires technical and security skills that is only available in the dealer's service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by consumers without the need of dealers.
