Transponder Chips

If your car was built in the past 20 years, chances are it contains a transponder chip within of it. It's the small piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.

When it is activated by an electromagnetic field, the chip emits a low-level signal. This signal is then absorbed by the special antenna that is positioned around the barrel that controls your ignition in your car. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the right one for your specific vehicle.

This prevents the vehicle from being started by hot-wiring, or by altering the key. The chip in the car key confirms that the owner is the one who is the owner of the vehicle. This helps to reduce the risk of theft from your car.

Regular transponder keys are shaped like regular keys, but with a plastic top. The chip is contained within the plastic part of the key, and there are a few different types of cuts on these keys: a regular cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will then get absorbed by the chip, causing it to transmit a signal back to the car. If the computer inside the car recognizes the signal as correct, it will disable vehicle immobilizer so that the engine can start.

If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and will warn you with flashing lights and siren. This is designed to discourage people from attempting to alter the vehicle, but it's not a 100% security measure. A skilled and skilled criminal could still bypass this system by using a specific device that blocks the signal.

You can see that the transponder is an excellent option. This is something that all vehicle owners should consider if they want to protect their investment and minimize the chance of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely or making noises to aid in finding a car in a parking lot Key fobs today can also switch on a heated steering wheel or roll down all windows with a single press. Many of these extra features might seem useful however they could make it harder for you to keep the track of your car keys.

Key fobs make use of radio frequencies to communicate with each other and with the car. The frequencies are transmitted by a small antenna inside the middle of the key. This signal is encrypted to block other key fobs from intercepting or replicating the signal.

There are several ways to program a key fob depending on your vehicle's make and model. It is possible to do this yourself, but the majority of newer vehicles require a dealer or professional locksmith to program a replacement or a second fob.

When you press the button on your key fob it transmits an encoded code to the car's receiver that it is paired with. The receiver compares the information with the 'allowed signals' that are stored in the key fob, and then it opens or closes the car's door. If the information doesn't match the fob's information, the car won't be allowed to run.

After the car has been paired with a specific fob, it only accepts signals from that device. In turn, other fobs won't work with the vehicle even if they appear similar. This protects the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control over the vehicle.

Most newer car dealers will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise that is only available in the dealer's service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems can be programmed by the consumer without the need for a dealership.
