Transponder Chips

If your car was built within the last 20 years, then it contains a transponder chip within of it. It's a tiny plastic thing inside the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.

The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is fitted around the barrel that controls your ignition in your vehicle. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the right one for your car.

This is the reason why doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip inside the key also confirms that you are the legal owner of the vehicle. This helps to reduce the risk of theft from your car.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer onboard the car detects the signal as valid it will turn off the car immobilizer so that the engine can start.

If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine, and will notify you via flashing lights and an alarm. This function is designed to discourage individuals from tampering with the vehicle. However it's not an absolute security measure. A skilled and determined thief could still be able to get around this system using a special device to detect the signal.

As you can see, there are quite a number of advantages to having transponder keys. All car owners should consider this in order to safeguard their investment and reduce the chance of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car from a distance or making noises to aid in finding a car in a parking space Key fobs today can also turn on the heated steering wheel or roll down all of the windows with a single press. Many of these extra features may seem convenient, but they can also make it difficult for you to keep the keys to your car.

Key fobs make use of radio frequencies to connect with one another and with the car. These frequencies are sent through a small antenna located inside the middle of the key. This communication is encrypted, which helps stop others from stealing and retransmitting the signal.

Keyfobs can be programmed in a variety of ways depending on the model and brand of your vehicle. You can sometimes do this yourself, but most newer vehicles require a locksmith shop or a professional to program a replacement or a second fob.

When you press the button on your key fob the microchip inside sends an encoded code to the car's radio that it is paired with. The receiver then compares this information to the 'allowed' signals stored in the fob and then either locks or opens the door. If the information doesn't match an chirping sound is heard and the car isn't permitted to function.

Once the car is linked with a specific fob it will only receive signals from that device. Other fobs will not work with the reprogram car keys, despite the fact that they appear similar. This ensures the security of the computer system of the vehicle and stops unauthorized key fobs gaining control of it.

The majority of newer 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 knowledge to create a replacement fob is in the service department of a dealer. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems can be programmed by customers without the need of dealers.
