Transponder Chips

Transponder chips are likely be found in cars manufactured in the last 20 years. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.

The chip sends out 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 car's computer system to verify that the transponder chip that is in the key is the correct one for your particular car.

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

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the onboard car computer recognizes this signal as being the correct one, it will shut down the vehicle immobilizer and allow the engine to start.

If the car does not recognize the transponder signal as being the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage individuals from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined thief may still be able to bypass this system by employing a device designed to take over the signal.

Key Fobs

These extra features could make it difficult to locate your car keys.

Key fobs are able to communicate with each other and the car using radio frequencies that are transmitted through an antenna that is located in the center of the key. This communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.

There are a few different ways to program a key fob, based on your vehicle's model and make. Some cars allow you to do this by yourself. However, the majority of newer models require you to visit a professional locksmith or dealer to program a new key fob, or an alternative one.

When you press a key fob's button the microchip inside sends a code to the car's receiver that it is linked to. The receiver compares the information with the 'allowed signals' that are stored on the key fob and then it opens or closes the car's door. If the information isn't in line, a chirping sound is heard and the car isn't able to operate.

Once the car is linked with a particular fob, it will only accept signals from that device. In turn, other fobs won't work with the vehicle even though they look the same. This protects the integrity of the computer system in the car and blocks unauthorised key fobs from taking control of it.

Most newer car dealerships will only work with cars with original fobs or genuine replacements supplied by the manufacturer. The reason for this is that the only place with the experience to design the replacement fob is the service department of a dealer. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by customers without the need of an authorized dealer.
