Transponder Chips
Transponder chips are likely be found in vehicles manufactured in the last 20 years. It's a small plastic piece inside the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is then taken up by an antenna that is attached to the ignition barrel. The computer system of the vehicle will then confirm that the key's transponder chip is the correct one for your car.
This is what prevents hot-wiring or tampering with the ignition system of your vehicle to turn it on. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This helps to prevent car theft.
Transponder keys look like regular keys made of metal but have a plastic cap. The chip itself is housed in the plastic portion of the key and there are different cuts that can be found on the keys: a standard cut laser cut (also called a sidewinder key) or Ford Tibbe key.
The circuit in the induction coil emits an electrical signal when the transponder is put into an ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the onboard car computer recognizes this signal as the right one, it will shut down the vehicle's immobilizer and allow the engine to start.
If the car isn't able to recognize the transponder as being the proper signal, it will not start the engine and alert you with flashing lights and an alarm. This system is designed to deter individuals from tampering with the vehicle. However it isn't an absolute security measure. A skilled and committed thief could still be able to bypass this system by using a special device to take over the signal.
As you can see, there are quite a few advantages to getting a transponder key. Every car owner should consider this 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 turn on the car remotely, emit chirping sounds to aid in finding the car, or turn on the heated steering wheel. These extra features can make it difficult to find your car keys.
Key fobs use radio frequencies to communicate with one another and with the car. The frequencies are transmitted through a small antenna located inside the middle of the key. This signal is encrypted to block other key fobs from stealing or stealing the signal.
There are several ways to program a key fob, based on your vehicle's model and make. Some cars allow you to do this yourself. However, the majority of newer models require you to visit a professional locksmith or dealer to program a new key fob or additional one.
When you press a key fob's button, the microchip inside transmits an informational code to the car's receiver that it is paired with. The receiver compared the information with the 'allowed signals' stored in the key fob and then locks or opens the car's doors. If the data doesn't match, a chirping sound is heard and the car isn't permitted to function.
After the car has been paired with a specific fob, it can only receive signals from the device. Other fobs will not work with the car, even though they look identical. This protects the integrity of the vehicle's computer system, and also to stop 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 that are offered by the manufacturer. It is because the only place that has the experience to design an appropriate replacement fob is the service department of a dealer. Some aftermarket fobs, usually those from older models that have less sophisticated systems can be programmed without the need for a dealership.
