Transponder Chips

Transponder chips are likely be found in vehicles manufactured in the last 20 years. It's the small piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your vehicle.

When it is activated by an electromagnetic field, the chip emits a low-level signal. The signal is taken up by an antenna attached to the ignition barrel. This allows the computer in your vehicle system to determine if the transponder chip in the key is the correct one for your particular car.

This prevents the vehicle from being started by hot-wiring, or by manipulating. The chip in the key also proves that you are the legal owner of the vehicle. This helps to prevent car theft.

Regular transponder keys are designed like regular metal keys with a plastic top. The chip is contained within the plastic part of the keys. There are various cuts that are a standard cut, laser cut (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe.

A circuit within the induction coil will emit a signal when the transponder is put into an ignition barrel. The signal will be absorbed by the chip, causing it to transmit a signal back to the car. If the computer onboard the car detects the signal as correct it will turn off the car immobilizer, allowing the engine to start.

If the car doesn't recognize the transponder as a valid signal, it won't start the engine and will alert you with flashing lights and a siren. This is designed to discourage people from trying to alter the vehicle, however it is not a foolproof security measure. A skilled and determined thief may still be able to get around this system employing a device designed to take over the signal.

It is evident that a transponder is a great option. Every car owner should consider this when they want to safeguard their investment and decrease the risk of theft.

Key Fobs

Key fobs today do more than just lock and unlock doors. They can also start the car remotely, make chirping noises to aid in finding the car or turn on the heated steering wheel. Many of these extra features may seem convenient but they could make it difficult for you to keep the track of 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 communication is encrypted, which helps to keep others from stealing and replicating the signal.

Keyfobs can be programmed in a variety of ways depending on the make and model of your car. You may be able to do it yourself, but the majority of newer automobiles require a dealer or professional locksmith to program a replacement or additional fob.

When you hit the button on a key fob the microchip inside sends an informational code to the car's receiver it is paired with. The receiver compares the information with the 'allowed signals' stored on the key fob and then it opens or closes the car door. If the data doesn't match, a chirping sound is heard and the car isn't able to operate.

Once the car key programmed is linked with a specific fob, it will only receive signals from that device. As a result, other fobs won't be able to work with the vehicle even if they appear similar. This safeguards the integrity of the computer system of the car and prevents unauthorised key fobs from taking control over it.

Most newer car dealerships will only accept vehicles that have original fobs or genuine replacements supplied by the manufacturer. This is because preparing a replacement fob requires technological and security knowledge that can only be found in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems can be programmed by customers without the need for an authorized dealer.
