Transponder Chips

Transponder chips are likely to be found in cars manufactured in the last 20 years. It's the small plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.

When activated by an electro-magnetic field the chip emits a low level signal. This signal is then absorbed by a special antenna attached to the ignition barrel. This allows the computer in your vehicle system to confirm that the transponder chip that is in the key is the right one for your specific vehicle.

This is what stops doing hot-wiring or altering the ignition system of the vehicle to turn it on. The chip in the key also proves that you are the legitimate owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.

Transponder keys that are regular in shape like regular keys and have an outer layer of plastic. The chip is inside the plastic part of these keys. There are several different cuts: a standard cut, laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the computer onboard the car is able to recognize the signal as being correct it will turn off the vehicle immobilizer to allow the engine start.

If the vehicle does not recognize the transponder signal as the proper one, it will prevent the engine from starting and will notify you by flashing its lights and sounding a siren. This function is designed to discourage individuals from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and skilled criminal can still get around this system by using a specific device that blocks the signal.

Key Fobs

Key fobs today can be more than just a way to lock and unlock doors.

A lot of these additional features may appear convenient, but they can also make it difficult for you to keep track of your car keys.

Key fobs make use of radio frequencies to communicate with one another and the car. These frequencies are transmitted through a small antenna located in the middle of the key. This communication is encrypted, which helps prevent others from intercepting and replicating the signal.

There are a few different ways to program a key fob, based on the make and model. Some cars allow you to do this yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order to program a new key fob, or an alternative one.

When you press the button on your key fob it transmits an informational code to the car's receiver it is linked to. The receiver compares this information with the 'allowed' signals stored on the fob and either opens or locks the door. If the information does not match the signals, the car will not be allowed to run.

After the car has been associated with a particular fob, it will only accept signals from the device. This means that other fobs will not work with the vehicle, even though they have the same appearance. This protects the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.

Most newer car dealerships will only deal with cars that have original fobs or genuine replacements supplied by the manufacturer. The reason for this is that the only place with the expertise to prepare a replacement fob is in the service department of the dealer. Certain aftermarket fobs, typically those from older models that have less advanced systems, can be programmed without the need for a dealership.
