Transponder chips are likely to be found in vehicles manufactured within the last 20 years. It's the small plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your car.
When it is activated by an electro-magnetic field the chip emits a low level signal. This signal then gets amplified by the specific antenna that is positioned around the ignition barrel of your car. This allows the vehicle's computer system to confirm that the transponder chip inside the key is the right one for the car you have.
This stops the vehicle from being started by hot-wiring or tampering. The chip in the car key confirms that the owner is the one who is the owner of the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular keys and have an outer layer of plastic. The chip is contained in the plastic portion of the key, and there are a few different types of cuts on these keys: a standard cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.
A circuit within the induction coil will emit signals when the transponder is inserted into the ignition barrel. The signal will then get absorbed by the chip, causing it to send a signal back to the car. If the onboard car computer recognizes this signal as the correct one, it will disable the vehicle's immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and will alert you with flashing lights and a siren. This feature is intended to discourage people from attempting to tamper with the vehicle, however it is not a foolproof security measure. A skilled and determined criminal might be able get around this system using a device that can detect the signal.
It is evident that the transponder is an excellent option. All car owners must take this into consideration if they wish to protect their investment and decrease theft risk.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making sound chirps to help locate the car in a parking lot, today's key fobs can also activate the heated steering wheel or open all windows with a single press. These additional features can make it difficult for you to find your car keys.
Key fobs use radio frequencies to communicate with each other and the car. The frequencies are transmitted through a small antenna located inside the middle of the key. This communication is encrypted to block other key fobs from stealing or modifying the signal.
You can program a keyfob in different ways based on the make and model of your vehicle. Some cars allow you to do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order to program a new key fob or an additional one.
When you press a key fob's button, the microchip inside transmits an informational code to the car's receiver it is linked to. The receiver compared the information with the 'allowed signals' stored in the key fob, and then locks or opens the car's door. If the data doesn't match, a chirping sound is heard and the car isn't allowed to function.
Once the car has been associated with a particular fob, it will only accept signals from the device. As a result, other fobs won't be able to work with the vehicle even if they appear similar. This safeguards the integrity of the computer system in the vehicle and stops unauthorised key fobs from taking control of it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security skills that is only available in the dealer service department. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems -- can be programmed by the consumer without the need of an authorized dealer.
