Transponder Chips

If your car is made within the last 20 years, chances are it contains a transponder chip within of it. This is the little plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.

When activated by an electro-magnetic field, the chip emits a low-level signal. The signal is received by a specific antenna that is attached to the ignition barrel. This allows the car's computer system to confirm that the transponder chip in the key is the correct one for the car key reprogram you have.

This prevents the vehicle from being started through hot-wiring, or by tampering. The chip inside the key verifies that the owner is the one who owns the vehicle. This can reduce car theft.

Transponder keys look like normal keys, but with a plastic cap. The chip is located inside the plastic portion of these keys. There are several different cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.

The circuit in the induction coil will emit signals when the transponder is inserted into ignition barrel. The signal will then get taken up by the chip and cause it to transmit a signal back to the car. If the computer on the car recognizes this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to begin.

If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and will alert you with flashing lights and an alarm. This feature is designed to discourage those who would attempt to alter the vehicle. However it isn't an absolute security measure. A skilled and determined thief could still bypass this system using a special device that detects the signal.

As you can see, there are quite a few advantages to getting a transponder key. Every car owner must take this into consideration in order to safeguard their investment and reduce the chance of theft.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely, or making sound chirps to help locate a car in a parking lot, today's key fobs can also turn on a heated steering wheel or roll down all windows with a single button push. These additional features can make it difficult for you to find your car keys.

Key fobs communicate with each with the car via radio frequencies which are transmitted by an antenna in the middle of the key. The communication is encrypted, which helps prevent others from intercepting and replicating the signal.

There are a few different ways to program a key fob, based on the model and make. Some cars allow you to do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer 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 with which it is linked. The receiver compared this information to the signals that are allowed inside the fob, and either opens or locks the door. If the information doesn't match an chirping sound is heard and the car isn't allowed to function.

Once the car is paired with a particular fob, it will only receive signals from that device. This means that other fobs won't be able to work with the vehicle, even though they appear similar. This protects the integrity of the car's computer system, and also to stop unauthorized key fobs from gaining control of the vehicle.

The majority of newer dealerships will only deal with vehicles that have original fobs or genuine replacements supplied by the manufacturer. This is because the only place with the knowledge to create a replacement fob is in the service department of the dealer. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems -- can be programmed by the consumer without the need of a dealership.
