Transponder Chips
If your car was manufactured in the past 20 years, it is likely that it contains a transponder chip within of it. It's a tiny plastic piece in the head of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
When activated by an electro-magnetic field the chip emits a low-frequency signal. This signal then gets absorbed by the special antenna that is attached to the ignition barrel of your vehicle. The computer system in the vehicle can then verify that the key's transponder chip is the correct one for your car.
This stops the vehicle from being started by hot-wiring, or by manipulating. The chip inside the key confirms that the owner is the one who is the owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
Transponder keys resemble normal keys but they have caps made of plastic. The chip is located inside the plastic part of the keys. There are several different cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal will be absorbed by the chip, causing it to transmit a signal back to the car. If the computer onboard the car is able to recognize the signal as correct, it will disable vehicle immobilizer to allow the engine start.
If the car does not recognize the transponder signal as the proper one, it will stop the engine from starting and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage people from trying to tamper with the vehicle, but it is not a foolproof security measure. A determined and skilled thief could still evade this system with a specially designed device that intercepts the signal.
It is evident that the transponder is a good option. This is something that all vehicle owners should consider if want to safeguard their investment and reduce 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 keys of today can also activate the heated steering wheel or roll down all windows with just a single push. These extra features can make it difficult for you to find your car keys.
Key fobs communicate with each other and the car using radio frequencies that are transmitted via an antenna in the middle of the key. The transmission is encrypted, which helps to prevent others from intercepting and retransmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the make and model of your car. It is possible to do this yourself, but the majority of newer cars require that you visit an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on a key fob the microchip transmits an indication to the receiver in the car with which it is paired. The receiver compares the information with the 'allowed signals' that are stored on the key fob and then locks or opens the car's door. If the information does not match, the car will not be allowed to run.
After the car has been paired with a specific fob, it can only receive signals from the device. In turn, other fobs won't be able to work with the vehicle even if they have the same appearance. This protects the integrity of the computer system in the vehicle and stops unauthorized key fobs gaining control over it.
The majority of newer dealerships will only deal with cars that have original fobs, or genuine replacements supplied by the manufacturer. The reason for this is that the only place with the knowledge to create a replacement fob is in a dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by the consumer without the need of a dealership.
