Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the last 20 years. This is a little piece of plastic inside the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
When it is activated by an electromagnetic field, the chip emits a low level signal. The signal is absorbed by a special antenna that is attached to the ignition barrel. The computer system in the vehicle will then confirm that the chip in the key's transponder is the right one for your vehicle.
This prevents the vehicle from being started by hot-wiring, or by tampering. The chip in the key also verifies that you are the legitimate owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys resemble normal keys but they have a plastic cap. The chip itself is housed within the plastic part of the key and there are a few different kinds of cuts available on these keys: a standard cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
A circuit within the induction coil will emit a signal when the transponder is inserted into ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer inside the car detects the signal as valid it will turn off the vehicle immobilizer so that the engine can start.
If the car doesn't recognize the transponder as a valid signal, it will not start the engine and will alert you with flashing lights and an alarm. This is designed to deter people from trying to tamper with the vehicle, however it's not a 100% security measure. A skilled and determined thief may still be able to get around this system using a device that can take over the signal.
As you can see, there are quite a few advantages to getting a transponder key. This is something that all car owners should consider if they are looking to safeguard their investment and decrease the chance of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start your car from a distance, make chirping sounds to aid in finding a car or turn on the heated steering wheel. Many of these extra features might seem useful, but they can also make it difficult for you to keep the keys to your car.
Key fobs communicate with each with the car via radio frequencies that are transmitted via an antenna in the middle of the key. This communication is encrypted to block other key fobs from stealing or modifying the signal.
There are several ways to program a key fob depending on your vehicle's model and make. Certain models allow you to do this by yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order for them program a replacement key fob, or an alternative one.
When you press a key fob's button the microchip inside sends an informational code to the car's radio that it is linked to. The receiver compares the information with the 'allowed signals' that are stored on the key fob and then it opens or closes the car's doors. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to operate.
Once the car has been paired with a specific fob, it will only accept signals from that device. In turn, other fobs won't be able to work with the vehicle, even though they appear similar. This protects the integrity of the car's computer system, and also to stop unauthorized key fobs from gaining control of the vehicle.
The majority of newer dealerships will only accept vehicles that have original fobs or genuine replacements supplied by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security skills that is only available in the dealer service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems -- can be programmed by consumers without the need of a dealership.
