Transponder Chips
Transponder chips are likely be found in cars manufactured within the past 20 years. It's the small plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. 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 chip in the key's transponder is the correct one for your car.
This is what stops doing hot-wiring or altering the ignition system of the vehicle to get it started. The chip inside the key ensures that the owner is the person who owns the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular keys, but with a plastic top. The chip is located inside the plastic portion of these keys. There are several different cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the car's computer recognizes this signal as being the correct one, it will shut down the immobilizer on the vehicle and allow the engine to begin.
If the vehicle does not recognize the transponder signal as the proper one, it will keep the engine from running and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage people from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and determined criminal could still be able to bypass this system by using a special device to take over the signal.
You can see that the transponder is an excellent option. This is something that all car owners should consider if they want to safeguard their investment and minimize the risk of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also turn on the vehicle remotely, make chirping noises to help locate the car or switch on the heated steering wheel. Many of these extra features might seem useful but they could make it harder for you to keep track of your car keys.
Key fobs use radio frequencies to communicate with one another and the car. These frequencies are transmitted via a small antenna that is located in the middle of the key. This communication is encrypted, which helps to prevent others from intercepting and replicating the signal.
You can program a keyfob in a variety of ways depending on the model and brand of your vehicle. Some cars allow you to do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order for them program a replacement key fob or an additional one.
When you press the button on your key fob, the microchip inside transmits a code to the car's radio that it is linked to. The receiver compares this information with the 'allowed' signals inside the fob, and either opens or locks the door. If the information isn't in line an chirping sound is heard and the car isn't allowed to function.
After the car has been paired with a specific fob, it can only receive signals from the device. As a result, other fobs won't be able to work with the vehicle even if they appear similar. This protects the integrity of the computer system in the car and prevents unauthorised key fobs from taking control of it.
Most newer car dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. The reason for this is that the only place that has the knowledge to create the replacement fob is the service department of a dealer. Certain aftermarket fobs, typically ones for older models with less advanced systems can be programmed without the need for a dealer.
