Transponder Chips
If your car was manufactured within the last 20 years, chances are it contains a transponder chip within of it. It's the small piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
When it is activated by an electro-magnetic field the chip emits a low level signal. The signal is then amplified by the specific antenna that is positioned around the ignition barrel of your car. This allows the vehicle's computer system to determine if the transponder chip inside the key is the right one for your specific vehicle.
This is what prevents hot-wiring or tampering with the ignition system of the vehicle to get it started. The chip in the key also proves that you are the legitimate owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular keys and have a plastic top. The chip is located inside the plastic part of these keys. There are various cuts that are a standard cut, Laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.
A circuit inside the induction coil emits signals when the transponder is inserted into ignition barrel. programming car key will then get received by the chip, causing it to send a signal back to the car. If the computer in the car recognizes the signal as correct, it will disable vehicle immobilizer to allow the engine start.
If the car does not recognize the transponder signal as the correct one, it will prevent the engine from starting and will notify you by flashing its lights and sounding an alarm. This function is designed to discourage people from tampering with the vehicle. However it's not an absolute security measure. A skilled and skilled criminal could still bypass this system by using a specific device that intercepts the signal.
It is evident that the transponder is a good option. This is something that all car owners should think about if they are looking to safeguard their investment and decrease the chance of theft.
Key Fobs
Key fobs today be more than just a way to lock and unlock doors. They can also start your car remotely, emit chirping sounds to help locate the car or turn on the heated steering wheel. Many of these extra features might seem useful however they could make it difficult for you to keep the track of your car keys.
Key fobs utilize radio frequencies to communicate with each other and the car. These frequencies are sent by a small antenna inside the middle of the key. The transmission is encrypted, which helps to stop others from stealing and retransmitting the signal.
Keyfobs can be programmed in various ways based on the model and brand of your car. It is possible to do this yourself, but the majority of newer cars require that you visit a dealer or professional locksmith to program a replacement or a second fob.
When you press a key fob's button it transmits an informational code to the car's receiver it is linked to. The receiver compares this information to the 'allowed' signals in the fob and then either locks or opens the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't allowed to operate.
Once the car is linked with a particular fob, it will only receive signals from that specific device. In turn, other fobs won't work with the vehicle even if they appear similar. This helps to protect the integrity of the car's computer system and prevent unauthorized key fobs from gaining control of the vehicle.
Most dealerships with newer cars will only work with cars that have original fobs, or genuine replacements offered by the manufacturer. The reason for this is that the only place that has the experience to design the replacement fob is the service department of a dealer. Some fobs from the aftermarket, especially ones for older models with less sophisticated systems, can be programmed without the need for a dealer.
