Transponder Chips

If your car was built in the last 20 years, then it has a transponder inside of it. It's a tiny piece of plastic in the head of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.

The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the correct one for your particular car.

This prevents the vehicle from being started by either hot-wiring or by altering the key. The chip inside the key also proves that you are the legitimate owner of the vehicle. This will help reduce car theft.

Transponder keys look like regular metal keys, but with a plastic cap. The chip is inside the plastic portion of these keys. There are a variety of cuts: a standard cut, 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 placed in the ignition barrel. The signal will be absorbed by the chip and cause it to transmit a signal to the car. If the computer on the car recognizes this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to start.

If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine and alert you with flashing lights and a siren. This feature is designed to discourage people from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and determined thief may still be able to escape this security system by employing a device designed to detect the signal.

It is evident that the transponder is a good option. All car owners should take this into consideration when they want to safeguard their investment and decrease the risk of theft.

Key Fobs

In addition to locking and unlocking doors, starting the car from a distance or making noises to aid in finding a car in a parking space Key fobs today can also switch on a heated steering wheel or open all windows with a single button press. A lot of these features might seem useful however they could make it difficult for you to keep the keys to your car.

Key fobs communicate with each other and the car using radio frequencies that are transmitted by an antenna in the middle of the key. This signal is encrypted to stop others from stealing or modifying the signal.

There are several ways to program a key fob depending on your vehicle's make and model. Certain cars let you do this by yourself. However, most newer models require you to visit an expert locksmith or dealer to program a replacement key fob or additional one.

When you hit the button on a key fob the microchip inside sends a code to the car's receiver it is linked to. The receiver then compares this information to the 'allowed' signals inside the fob, and either opens or closes the door. If the information doesn't match an chirping sound is heard and the car isn't able to operate.

Once the reprogramming car key has been associated with a particular fob, it only accepts signals from that device. Other fobs won't work with the car, even though they appear similar. This safeguards the integrity of the computer system of the car and prevents the use of unauthorized key fobs to gain control of it.

The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. The reason for this is that the only place that has the expertise to prepare an appropriate replacement fob is the service department of the dealer. Certain aftermarket fobs, typically those for older models with less advanced systems, can be programmed without the need for a dealership.
