They are equipped with diagnostic software that allows them to communicate with the computer, and they also have a bidirectional interface for working with the immobilizer system.

Transponder Chips

Transponder chips are likely to be found in cars manufactured within the past 20 years. This is the little plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.

When it is activated by an electromagnetic field the chip emits a low level signal. This signal is then received by a specific antenna attached to the barrel of ignition. The computer system in the vehicle can then verify that the chip in the key's transponder is the right one for your vehicle.

This is what stops doing hot-wiring or altering the vehicle's ignition system to start it. The chip in the car key verifies that the owner is the one who is the owner of the vehicle. This will help reduce car theft.

Transponder keys resemble regular keys made of metal but they have caps made of plastic. The chip is contained in the plastic portion of the key programmer, and there are a few different cuts that can be found on the keys: a cut laser cut (also known as a sidewinder key) or Ford Tibbe key.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer onboard the car detects the signal as correct, it will disable vehicle immobilizer so that the engine can start.

If the car isn't able to recognize the transponder as being the proper signal, it will not start the engine, and will warn you with flashing lights and siren. This is designed to deter people from trying to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and determined thief can still get around this system by using a specific device that detects the signal.

You can see that a transponder is a great option. This is something that all vehicle owners should consider if they want to protect their investment and reduce the risk of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely or making sound chirps to help locate a car in a parking space, today's key fobs can also turn on a heated steering wheel or roll down all of the windows with a single click. A lot of these additional features may appear convenient however they could make it more difficult to keep track of your car keys.

Key fobs use radio frequencies to connect with one another and the car. The frequencies are transmitted via a small antenna that is located inside the middle of the key. The signal is encrypted to stop others from intercepting or replicating the signal.

There are a few different ways to program a key fob based on the vehicle's model and make. Some cars allow you to do this by yourself. However, the majority of newer 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 a key fob, the microchip sends signals to the receiver in the car with which it is paired. The receiver compares the information with the permitted signals stored in the key fob and then locks or opens the car's door. If the information does not match the signals, the car will not be allowed to drive.

When a car is connected with a specific fob it will only accept signals from that device. This means that other fobs won't work with the vehicle even though they have the same appearance. This protects the integrity of the car's computer system and prevent unauthorised key fobs from taking control of the vehicle.

Most newer car dealers will only work on a car with 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. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by customers without the need for an authorized dealer.
