Transponder Chips
Transponder chips can be found in vehicles manufactured within the last 20 years. It's a tiny plastic piece inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is fitted around the barrel that controls your ignition in your car. 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 being started through hot-wiring, or by tampering. The chip inside the key also proves that you are the legitimate owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is contained within the plastic part of the keys. There are a variety of cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe.
A circuit within the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the computer inside the car recognizes the signal as being correct, it will disable vehicle immobilizer, allowing 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 siren. This is designed to deter people from trying to tamper with the vehicle, but it is not a foolproof security measure. A skilled and determined criminal may still be able to escape this security system by using a special device to intercept the signal.
As you can see there are quite number of benefits to having a transponder key. All car owners must take this into consideration when they want to safeguard their investment and decrease the risk of theft.
Key Fobs
Key fobs today be more than just a way to lock and unlock doors. They can also start your car from a distance, make chirping sounds to help locate a car, or turn on the heated steering wheel. These extra features could make it difficult to find your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies which are transmitted through an antenna that is located in the middle of the key. The signal is encrypted to stop others from intercepting or replicating the signal.
You can program a keyfob in various ways based on the model and make of your car. You may be able to do it yourself, but the majority of newer cars require that you visit a locksmith shop or a professional 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 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's doors. If the information doesn't match, a chirping sound is heard and the car isn't permitted to operate.
Once the car is paired with a specific fob it will only accept signals from that device. This means that other fobs won't be able to work with the vehicle even if they look the same. This helps to protect the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
The majority of newer dealerships will only deal with cars with original fobs or genuine replacements offered by the manufacturer. It is because the only place with the expertise to prepare an appropriate replacement fob is the service department of the dealer. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by consumers without the need of dealers.
