Transponder Chips

Transponder chips are likely to be found in vehicles manufactured within the last 20 years. This is a little plastic thing on the back of your key that houses an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.

The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is absorbed by a special antenna attached to the barrel of ignition. The computer system in the vehicle is then able to verify that the transponder chip of the key is the correct one for your car.

This prevents the vehicle from starting by either hot-wiring or by altering the key. The chip in the key also verifies that you are the legitimate owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

Transponder keys look like regular metal keys but they have caps made of plastic. The chip itself is housed inside the plastic portion of the key, and there are a few different types of cuts on these keys: a standard cut laser cut (also known as a sidewinder key) or Ford Tibbe key.

A circuit inside the induction coil emits an electrical signal when the transponder is placed in the ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the onboard car computer recognizes this signal as being the correct one, it will turn off the vehicle immobilizer and allow the engine to start.

If the car doesn't recognize the transponder as a valid signal, it won't start the engine and warn you with flashing lights and siren. This feature is intended to discourage people from trying to alter the vehicle, but it is not a foolproof security measure. A determined and skilled thief could still evade this system with a specially designed device that intercepts the signal.

You can see that the transponder is an excellent option. Every car owner should take this into consideration in order to safeguard their investment and minimize the chance of theft.

Key Fobs

These additional features could make it difficult to locate your car keys.

Key fobs are able to communicate with each other and with the car keys cutting and programming through radio frequencies which are transmitted by an antenna in the center of the key. This communication is encrypted, which helps prevent others from intercepting and re-transmitting the signal.

Keyfobs can be programmed in a variety of ways depending on the model and brand of your vehicle. Certain cars let you do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order to program a replacement key fob or additional one.

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

Once the car has been paired with a specific fob, it will only accept signals from that device. In turn, other fobs will not work with the vehicle even though they look the same. This ensures the security of the computer system of the car and prevents unauthorised key fobs from taking control of it.

The majority of newer dealerships will only accept vehicles that have original fobs or genuine replacements supplied by the manufacturer. This is because the only place with the expertise to prepare the replacement fob is the service department of the dealer. Some aftermarket fobs, usually those from older models with less sophisticated systems can be programmed with out the need for a dealership.
