Transponder Chips

If your car was built within the past 20 years, it is likely that it contains a transponder chip within of it. This is a little plastic thing on the back of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then absorbed by a special antenna attached to the ignition barrel. 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 is what stops from modifying or hot-wiring the vehicle's ignition system to get it started. The chip inside the key also proves that you are the legitimate owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip is located inside the plastic part of these keys. There are various cuts that are a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.

A circuit inside the induction coil will emit a signal when the transponder is put into ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer inside the car detects the signal as correct, it will disable vehicle immobilizer to allow the engine start.

If the car does not recognize the transponder signal as the right one, it will prevent the engine from starting and will alert you by flashing its lights and sounding an alarm. This system is designed to deter those who would attempt to alter the vehicle. However it isn't an absolute security measure. A skilled and determined thief can still get around this system with a specially designed device that intercepts the signal.

You can see that the transponder is an excellent option. This is something that all car owners should consider if they are looking to safeguard their investment and reduce the risk of theft.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely or making sound chirps to help locate a car in a parking space, today's key fobs can also switch on a heated steering wheel or roll down all windows with a single push. These additional features could make it difficult to find your car keys programmed.

Key fobs communicate with each other and with the programmable car keys through radio frequencies that are transmitted by a small antenna located in the center of the key. The communication is encrypted, which helps stop others from stealing and replicating the signal.

There are a few different ways to program a key fob depending on the vehicle's model and make. Certain models allow you to do this by yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order for them program a replacement key fob, or an alternative one.

When you hit the button on a key fob the microchip inside sends a code to the car's receiver it is linked to. The receiver then compares the data with the 'allowed signals' that are stored on the key fob and then opens or locks the car's doors. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to operate.

After the car has been connected to a specific fob, it only accepts signals from the device. This means that other fobs will not work with the vehicle even though they look the same. This safeguards the integrity of the computer system that runs the car and prevents unauthorised key fobs from taking control of it.

Most dealerships with newer cars will only deal with cars that have original fobs, or genuine replacements sold by the manufacturer. This is due to the fact that preparing an appropriate replacement fob key programmer requires technical and security expertise which can only be obtained in the dealer service department. Certain aftermarket fobs, typically those for older models that have less sophisticated systems can be programmed with out the need for a dealer.
