Transponder Chips

Transponder chips are likely be found in cars that were manufactured in the last 20 years. It's a tiny plastic piece on the back of your key that contains an RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.

When it is activated by an electromagnetic field, the chip emits a low-frequency signal. This signal is then taken up by the antenna that is fitted around the barrel that controls your ignition in your car. This allows the computer in your vehicle system to confirm that the transponder chip that is in the key is the correct one for the car you have.

This prevents the vehicle from being started through either hot-wiring or by tampering. The chip in the car key confirms that the owner is the person who is the owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.

Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is housed inside the plastic portion of the key, and there are different kinds of cuts available on these keys: a cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out a signal. The signal is received by the chip which then transmits a signal to the vehicle. If the computer on the car detects this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to begin.

If the car key programer does not recognize the transponder signal as being the correct one, it will keep the engine from running and will alert you by flashing its lights and sounding siren. This feature is designed to discourage people from attempting to alter the vehicle, but it's not a 100% security measure. A skilled and determined criminal might be able get around this system using a device that can intercept the signal.

As you can see there are quite few advantages to getting a transponder key. All car owners should consider this when they want to safeguard their investment and decrease theft risk.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely, or making chirping sounds to help find the car in a parking lot keys of today can also switch on a heated steering wheel, or open all windows with just a single press. These additional features could make it difficult to find your car keys.

Key fobs utilize radio frequencies to connect with one another and the car. These frequencies are sent through a small antenna located within the middle of the key. The signal is encrypted to prevent others from stealing or modifying the signal.

You can program a keyfob in different ways based on the model and make of your vehicle. It is possible to do this yourself, however most modern automobiles require a locksmith shop or a professional to program a replacement or an additional fob.

When you hit the button on a key fob it transmits a code to the car's receiver it is linked to. The receiver compares this information to the 'allowed' signals on the fob and either opens or closes the door. If the data does not match the fob's information, the car won't be allowed to operate.

Once the car is linked with a specific fob it will only receive signals from the device that is associated with it. In turn, other fobs will not work with the vehicle, even though they have the same appearance. This protects the integrity of the computer system of the car and prevents unauthorized key fobs gaining control over it.

The majority of newer dealers will only work on a car with original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place with the knowledge to create a replacement fob is in a dealer's service department. Certain aftermarket fobs, typically those for older models with less advanced systems, can be programmed without the need for a dealer.
