Transponder Chips

Transponder chips are likely to be found in cars manufactured within the past 20 years. It's a tiny plastic thing on the back of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.

The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is received by a specific antenna that is attached to the barrel of ignition. This allows the car's computer system to determine if the transponder chip inside the key is the correct one for the car you have.

This is what stops from modifying or hot-wiring the ignition system of your vehicle to turn it on. The chip inside the car key ensures that the owner is the person who is the owner of the vehicle. This will help reduce car theft.

Transponder keys appear like regular keys made of metal but have a plastic cap. The chip itself is housed inside the plastic portion of the key, and there are a few different cuts that can be found on the keys: a standard cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.

A circuit within the induction coil emits a signal when the transponder is placed in the ignition barrel. The signal will then get taken up by the chip and cause it to transmit a signal back to the car. If the onboard car computer detects this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to begin.

If the vehicle does not recognize the transponder signal as the proper one, it will stop the engine from running and will alert you by flashing its lights and sounding an alarm. This function is designed to discourage people from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and determined criminal could still be able to bypass this system by using a device that can detect the signal.

You can see that the transponder is a good option. All car owners must take this into consideration when they want to safeguard their investment and minimize theft risk.

Key Fobs

In addition to locking and unlocking doors, starting the car from a distance or making chirping sounds to help find 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 just a single press. These extra features can make it difficult for you to locate your car keys.

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

There are many ways to program a key fob depending on the make and model. Certain models allow you to do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a new key fob or an additional one.

When you press the button on your key fob, the microchip inside transmits an informational code to the car's receiver it is linked to. The receiver compared the information with the 'allowed signals' that are stored in the key fob, and then opens or locks the car's doors. If the information doesn't match, a chirping sound is heard and the car isn't allowed to operate.

After the car has been connected to a specific fob, it can only receive signals from that device. Other fobs will not work with the car, even if they appear like. This ensures the security of the computer system that runs the car and prevents the use of unauthorized key fobs to gain control over it.

The majority of newer dealerships will only work with vehicles that have original fobs, or genuine replacements supplied by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security knowledge that can only be found in the dealer's service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems -- can be programmed by the consumer without the need for a dealership.
