Transponder Chips
Transponder chips are likely be found in cars manufactured within the last 20 years. This is a little plastic thing inside the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is positioned around the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to confirm that the transponder chip that is in the key is the right one for your specific vehicle.
This prevents the vehicle from being started by either hot-wiring or by manipulating. The chip in the car key ensures that the owner is the one who owns the vehicle. This can help to reduce the possibility of theft from your vehicle.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip is housed in the plastic portion of the key and there are different cuts that can be found on these keys: a regular standard cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
The circuit in the induction coil will emit signals when the transponder is put into ignition barrel. The signal will be taken up by the chip and cause it to transmit a signal back to the car. If the computer inside the car is able to recognize the signal as valid it will turn off the car immobilizer, allowing the engine to start.
If the vehicle does not recognize the transponder signal as being the proper one, it will prevent the engine from starting and will alert you by flashing its lights and sounding a siren. This function is designed to discourage those who would attempt to alter the vehicle. However it isn't a foolproof measure of security. A skilled and committed thief might be able escape this security system by using a device that can intercept the signal.
As you can see there are quite a number of benefits to having transponder keys. All car owners should take this into consideration if they wish to protect their investment and minimize the chance of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start your car remotely, emit chirping sounds to help locate the car or turn on the heated steering wheel. These extra features can make it difficult for you to find your car keys.
Key fobs communicate with one other and the car using radio frequencies which are transmitted by an antenna in the center of the key. The transmission is encrypted, which helps prevent others from intercepting and retransmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the model and make of your vehicle. Certain cars let you do this 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 press the button on a key fob the microchip sends signals to the receiver in the vehicle with which it is paired. The receiver compared the information with the 'allowed signals' that are stored in the key fob and then it opens or closes the car's door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't allowed to function.
After the car has been associated with a particular fob, it can only receive signals from the device. Other fobs will not work with the car, even if they appear similar. This helps to protect the integrity of the car's computer system and prevent unauthorized key fobs from gaining control over 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 because the process of creating the replacement fob is a process that requires technological and security skills that can only be found in the dealer service department. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by consumers without the need of dealers.
