Transponder Chips
If your car is made within the past 20 years, then it has a transponder chip inside of it. This is the little plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your car.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is then absorbed by a special antenna that is attached to the barrel of ignition. The computer system of the vehicle can then verify that the key's transponder chip is the right one for your car.
This is the reason why doing hot-wiring or altering the ignition system of your vehicle to turn it on. The chip in the key also confirms that you are the legal owner of the vehicle. This can help to reduce car theft.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip is located inside the plastic part of the keys. There are various cuts such as a standard cut a Laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe.
The circuit in the induction coil will emit a signal when the transponder is inserted into the ignition barrel. The signal will then get absorbed by the chip and cause it to transmit a signal to the car. If the onboard car computer recognizes this signal as the right one, it will shut down the vehicle immobilizer and allow the engine to start.
If the car doesn't recognize the transponder as being the proper signal, it won't start the engine, and will warn you with flashing lights and an alarm. This function is designed to discourage individuals from tampering with the vehicle. However it's not an absolute security measure. A skilled and committed thief could still be able to get around this system employing a device designed to detect the signal.
You can see that a transponder is a great option. All car owners must take this into consideration in order to safeguard their investment and reduce the chance of theft.
Key Fobs
Key fobs today be more than just a way to lock and unlock doors. They can also start the car remotely, emit chirping sounds to help locate cars, or turn on the heated steering wheel. A lot of these additional features may seem convenient however they could make it more difficult to keep the keys to your car.
Key fobs communicate with each other and with the car through radio frequencies which are transmitted via an antenna in the middle of the key. The transmission is encrypted, which helps to keep others from stealing and replicating the signal.
You can program a keyfob in different ways based on the model and make 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 the microchip inside sends a code to the car's radio that it is linked to. The receiver compares this information to the signals that are allowed inside the fob, and either locks or opens the door. If the information isn't in line an chirping sound is heard and the car isn't allowed to operate.
Once the car is paired with a specific fob it will only accept signals from that specific device. As a result, other fobs won't work with the vehicle even if they have the same appearance. This ensures the security of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control of it.
Most dealerships with newer cars will only work with vehicles that have original fobs or genuine replacements sold by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise that is only available in the dealer's service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems -- can be programmed by consumers without the need of dealers.
