They have diagnostic software that enables them to communicate with computers and also provide a bidirectional interface for working with the immobilizer system.

Transponder Chips

Transponder chips can be found in cars manufactured within the last 20 years. It's a tiny piece of plastic 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.

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then absorbed by a special antenna that is attached to the barrel of ignition. The computer system in the vehicle can then verify that the key's transponder chip is the correct one for your car.

This prevents the vehicle from being started by either hot-wiring or by tampering. The chip inside the key also confirms that you are the legal owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

Transponder keys look like normal keys but have a plastic cap. The chip is contained in the plastic portion of the key, and there are a few different types of cuts on these keys: a standard cut, a 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 the ignition barrel. The signal will then get received by the chip and cause it to transmit a signal back to the car. If the car's computer recognizes this signal as being 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 key programming signal as the right one, it will keep the engine from starting and will alert you by flashing its lights and sounding a siren. This feature is intended to deter people from trying to tamper with the vehicle, however it isn't a foolproof 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 number of benefits to having a transponder key. All car owners must take this into consideration when they want to safeguard their investment and minimize the risk of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car from a distance or making sound chirps to help locate the car in a parking lot Key fobs today can also turn on the heated steering wheel or open all windows with a single button click. These extra features can make it difficult to locate your car keys.

Key fobs use radio frequencies to communicate with one another and with the car. These frequencies are transmitted via a small antenna that is located within the middle of the key. The transmission is encrypted, which helps to keep others from stealing and re-transmitting the signal.

You can program a keyfob in a variety of ways depending on the model and brand of your vehicle. Certain models allow you to do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order to program a new key fob or additional one.

When you press the button on a key fob, the microchip sends a signal to the receiver inside the car that it is paired. The receiver compared this information with the 'allowed' signals on the fob and either opens or locks the door. If the information does not match the fob's information, the car won't be allowed to drive.

Once the car is linked with a specific fob it will only receive signals from the device that is associated with it. Other fobs won't work with the car key cut and programed, despite the fact that they appear similar. This safeguards the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control of it.

The majority of newer dealerships will only deal with cars with original fobs, or genuine replacements sold by the manufacturer. This is because the only place with the experience to design an appropriate replacement fob is the service department of a dealer. Some aftermarket fobs, usually ones for older models with less sophisticated systems can be programmed with out the need for a dealer.
