Transponder Chips

Transponder chips can be found in cars that were manufactured in the last 20 years. This is the little plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.

When activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then taken up by the antenna that is fitted around the barrel that controls your ignition in your vehicle. The computer system in the vehicle will then confirm that the transponder chip of the key is the right one for your car.

This stops the vehicle from starting by hot-wiring or tampering. The chip in the car key ensures that the owner is the person who owns the vehicle. This helps to prevent car theft.

Transponder keys resemble regular keys made of metal but they have caps made of plastic. The chip itself is housed within the plastic part of the key, and there are a few different types of cuts on the keys: a cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.

A circuit within the induction coil emits a signal when the transponder is placed in the an ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to start.

If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine and will alert you with flashing lights and a siren. This system is designed to deter individuals from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and determined thief could still evade this system with a specially designed device that detects the signal.

Key Fobs

These additional features can make it difficult for you to locate your car keys.

Key fobs use radio frequencies to communicate with each other and with the car. These frequencies are sent through a small antenna located within the middle of the key. The signal is encrypted to stop others from stealing or modifying the signal.

There are many ways to program a key fob based on the vehicle's model and make. Certain cars let you do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a new key fob or an additional one.

When you press the button on a key fob, the microchip sends an indication to the receiver in the vehicle that it is paired. The receiver compared the information with the permitted signals stored on the key fob and then it opens or closes the car's doors. If the information isn't in line an chirping sound is heard and the car isn't able to function.

After the car has been connected to a specific fob, it will only accept signals from the device. Other fobs will not work with the car, despite the fact that they look like. This protects the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control of the vehicle.

Most newer car dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. The reason for this is that the only place with the expertise to prepare an appropriate replacement fob is the service department of a dealer. Some fobs from the aftermarket, especially those from older models with less sophisticated systems, can be programmed without the need for a dealership.
