Transponder Chips

If your car was manufactured in the past 20 years, chances are it has a transponder inside of it. This is a little plastic piece on the back of your key which contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.

When it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal is then absorbed by the special antenna that is attached to the barrel that controls your ignition in your car. This allows the car's computer system to verify that the transponder chip that is in the key is the right one for your particular car.

This prevents the vehicle from starting by either hot-wiring or by tampering. The chip in the key also proves that you are the legitimate owner of the vehicle. This can help to reduce car theft.

Regular transponder keys are shaped like regular keys and have a plastic top. The chip is housed within the plastic part of the key, and there are a few different cuts that can be found on the keys: a standard cut, a laser cut (also known as a sidewinder key), or a 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 on the car recognizes this signal as being the right one, it will turn off the vehicle's immobilizer and allow the engine to begin.

If the car does not recognize the transponder signal as the right one, it will keep the engine from starting and will notify you by flashing its lights and sounding an alarm. This function is designed to discourage people from tampering with the vehicle. However, it is not an absolute security measure. A skilled and determined criminal may still be able to get around this system employing a device designed to intercept the signal.

You can see that a transponder is a great option. All car owners must take this into consideration if they wish to protect their investment and reduce theft risk.

Key Fobs

Key fobs today be more than just a way to lock and unlock doors. They can also start your vehicle remotely, emit chirping sounds to help locate a car, or switch on the heated steering wheel. These additional features can make it difficult to find your car keys.

Key fobs communicate with each other and the car using radio frequencies which are transmitted by an antenna that is located in the middle of the key. This signal is encrypted to block other key fobs from intercepting or replicating the signal.

There are a few different ways to program a key fob, based on your vehicle's model and make. Some cars allow you to do this by yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a replacement key fob, or an alternative one.

When you press the button on your key fob, the microchip inside transmits an encoded code to the car's radio that it is paired with. The receiver compared this information to the 'allowed' signals inside the fob, and either opens or closes the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't able to function.

Once the car is paired with a specific fob, it will only accept signals from that device. In turn, other fobs won't be able to work with the vehicle even if they look the same. This is to safeguard the integrity of the reprogram car key's computer system and prevent unauthorized key fobs from gaining control over the vehicle.

Most newer car dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is because the only place that has the experience to design an appropriate replacement fob is a dealer's service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed car keys by the consumer without the need for an authorized dealer.
