Transponder Chips

Transponder chips can be found in cars that were manufactured in the last 20 years. This is a little plastic thing in the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.

When it is activated by an electro-magnetic field the chip emits a low level signal. This signal then gets absorbed by the special antenna that is positioned around the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to determine if the transponder chip inside the key is the correct one for your particular cheap car key programming.

This stops the vehicle from starting by either hot-wiring or by altering the key. The chip in the key also proves that you are the legal owner of the vehicle. This helps to reduce the risk of theft from your car.

If the onboard car computer recognizes this signal as the right one, it will shut down the immobilizer on the vehicle and allow the engine to start.

If the car doesn't recognize the transponder as being the proper signal, it will not start the engine and will notify you via flashing lights and a siren. This function is designed to discourage people from tampering with the vehicle. However it's not an unbreakable security measure.

Key Fobs

Key fobs today can offer more than locking 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. These additional features can make it difficult for you to locate your car keys.

Key fobs utilize radio frequencies to communicate with each other and the car. The frequencies are transmitted through a small antenna located within the middle of the key. This communication is encrypted to prevent others from stealing or modifying the signal.

There are many ways to program a key fob based on the vehicle's model and make. Some cars allow you to do it 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 additional one.

When you press the button on your key fob it transmits a code to the car's receiver that it is paired with. The receiver then compares this information with the 'allowed' signals stored inside the fob, and either opens or locks the door. If the information isn't in line an chirping sound is heard and the car isn't able to operate.

Once the car is paired with a particular fob, it will only accept signals from that specific device. As a result, other fobs won't work with the vehicle even if they look the same. This safeguards the integrity of the computer system in the vehicle and stops unauthorised key fobs from taking control of it.

The majority of newer dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security expertise that can only be found in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by the consumer without the need for dealers.
