They come with diagnostic software that enables them to communicate with computers, and they also have bidirectional interfaces to work with the immobilizer system.

Transponder Chips

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

The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is positioned around the barrel that controls your ignition in your vehicle. This allows the car's computer system to confirm that the transponder chip in the key is the correct one for the car you have.

This prevents the vehicle from being started by either hot-wiring or by tampering. The chip in the car key verifies that the owner is the one who owns the vehicle. This will help reduce car theft.


Transponder keys appear like normal keys but they have a plastic cap. The chip is inside 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.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer in the car recognizes the signal as being correct, it will disable vehicle immobilizer, allowing the engine to start.

If the vehicle doesn't recognize the transponder signal as being the proper one, it will stop the engine from starting and will alert you by flashing its lights and sounding an alarm. This is designed to deter people from trying to tamper with the vehicle, but it's not a 100% security measure. A determined and skilled thief could still evade this system using a special device that detects the signal.

As you can see there are quite few advantages to getting transponder keys. Every car owner must take this into consideration when they want to safeguard 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 the car in a parking lot Key fobs today can also switch on the heated steering wheel or roll down all windows with a single button press. A lot of these additional features might seem useful but they could make it more difficult to keep the keys to your car.

Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted via a small antenna located in the middle of the key. The transmission is encrypted, which helps to prevent others from intercepting and replicating the signal.

There are many ways to program a key fob based on your vehicle's make and model. You may be able to do it yourself, however most modern automobiles require a dealer or professional locksmith to program a replacement or a second fob.

When you press the button on a key fob the microchip transmits an indication to the receiver inside the car with which it is linked. 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, 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 receive signals from the device that is associated with it. In turn, other fobs won't be able to work with the vehicle even though they appear similar. This helps to protect the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.

G28 Car Keys Solutions will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security expertise that can only be found in the dealer's service department. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems -- can be programmed by customers without the need of an authorized dealer.
