Transponder Chips

Transponder chips can be found in vehicles manufactured within the past 20 years. This is a little piece of plastic on the back of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.

When it is activated by an electromagnetic field the chip emits a low level signal. This signal then gets amplified by the specific antenna that is attached to the ignition barrel of your car. This allows the car's computer system to confirm that the transponder chip that is in the key is the correct one for the car you have.

This stops the vehicle from being started through hot-wiring, or by altering the key. The chip inside the key ensures that the owner is the person who owns the vehicle. This can help to reduce the possibility of theft from your vehicle.

Regular transponder keys are shaped like regular keys and have a plastic top. The chip is located inside the plastic part of these keys. There are several different cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe.

A circuit inside the induction coil will emit signals when the transponder is inserted into an ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the computer onboard the car recognizes the signal as being correct it will turn off the car immobilizer so that the engine can start.

If the vehicle doesn't recognize the transponder as the correct signal, it won't start the engine, and will notify you via flashing lights and an alarm. This feature is designed to discourage people from attempting to hack into the vehicle, but it is not a foolproof security measure. A skilled and committed thief could still be able to escape this security system by employing a device designed to intercept the signal.

Many of these extra features might seem useful however they could make it more difficult to keep track of your car keys.

Key fobs use radio frequencies to communicate with each other and with the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.

Keyfobs can be programmed in various ways based on the model and make of your car. Some cars allow you to do this by yourself. However, the majority of newer models require you to visit an expert 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 transmits a signal to the receiver in the car key cut and programed with which it is paired. The receiver compared the information with the 'allowed signals' stored in the key fob and then locks or opens the car door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to function.

When a car is connected with a specific fob it will only receive signals from the device that is associated with it. Other fobs will not work with the car, even though they look similar. This is to safeguard the integrity of the vehicle's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle.

The majority of newer dealers will only work on a car with original fobs or Reprogramming car keys genuine replacements supplied by the manufacturer. The reason for this is that the only place with the experience to design a replacement fob is in the service department of the dealer. Some fobs from the aftermarket, especially those for older models with less advanced systems can be programmed with out the need for a dealer.
