Transponder Chips
Transponder chips are likely be found in vehicles manufactured within the last 20 years. It's a small plastic piece in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
When activated by an electro-magnetic field the chip emits a low level signal. The signal is taken up by an antenna attached to the ignition barrel. The computer system of the vehicle is then able to verify that the key's transponder chip is the correct one for your car.
This stops the vehicle from starting by hot-wiring or altering the key. The chip in the key also proves that you are the legitimate owner of the vehicle. This can help to reduce car theft.
Transponder keys that are regular in shape like regular metal keys with a plastic top. The chip is located inside the plastic portion of the keys. There are a variety of cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
A circuit inside the induction coil will emit a signal when the transponder is placed in the the ignition barrel. The signal will then get received by the chip and cause it to send a signal back to the car. If the computer on the car recognizes this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine, and will alert you with flashing lights and siren. This is designed to discourage people from trying to tamper with the vehicle, however it isn't a foolproof security measure. A skilled and determined thief could still be able to escape this security system by using a special device to intercept the signal.
You can see that the transponder is an excellent option. This is something that all car owners should consider if are looking to safeguard their investment and reduce the chance of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely or making sound chirps to help locate a car in a parking lot, today's key fobs can also turn on the heated steering wheel or roll down all windows with a single click. These extra features could make it difficult to find your car keys.
Key fobs use radio frequencies to connect with one another and with the car. These frequencies are transmitted via a small antenna that is located within the middle of the key. The communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.
There are a few different ways to program a key fob based on the model and make. It is possible to do this yourself, however most modern vehicles require an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on your key fob the microchip inside sends an encoded code to the car's receiver that it is paired with. The receiver compares the information with the 'allowed signals' that are stored in the key fob and then it opens or closes the car door. If the data doesn't match, a chirping sound is heard and the car isn't allowed to operate.
Once the car has been paired with a specific fob, it can only receive signals from the device. In turn, other fobs won't work with the vehicle even though they appear similar. This protects the integrity of the computer system of the car and blocks unauthorised key fobs from taking control over it.
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. This is because the process of creating a replacement fob requires technological and security expertise that can only be found in the dealer service department. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by the consumer without the need for a dealership.
