A keyprogrammer can reprogram the transponder chip of an entirely new mechanical key or key fob. It is also able to copy the data from an existing key which allows duplicate keys to be created. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that enables them to communicate with computers and also provide a bidirectional interface for working with the immobilizer system.

Transponder Chips

Transponder chips are likely to be found in vehicles manufactured within the past 20 years. It's a tiny piece of plastic in the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.

The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then received by a specific antenna that is attached to the ignition barrel. This allows the car's computer system to confirm that the transponder chip inside the key is the correct one for your particular car.

This prevents the vehicle from being started by either hot-wiring or by altering the key. The chip in the key also verifies that you are the legitimate owner of the vehicle. This helps to prevent car theft.

Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is inside the plastic part of the keys. There are several different cuts: a standard cut, Laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer inside the car is able to recognize the signal as being correct it will turn off the car immobilizer, allowing the engine to start.

If the car does not recognize the transponder signal as the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This function is designed to discourage those who would attempt to alter the vehicle. However, it is not a foolproof measure of security. A determined and skilled thief could still evade this system with a specially designed device that detects the signal.

You can see that the transponder is an excellent option. All car owners should consider this if they wish to protect their investment and reduce theft risk.

Key Fobs

Key fobs today offer more than locking and unlock doors. They can also start the car from a distance, make chirping sounds to help locate cars, or turn on the heated steering wheel. These additional features can make it difficult to find your car keys.

Key fobs communicate with each other and with the car through radio frequencies that are transmitted via an antenna that is located in the middle of the key. This communication is encrypted, which helps prevent others from intercepting and replicating the signal.

Keyfobs can be programmed in a variety of ways depending on the make and model of your car. Some cars allow you to do this by yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order to program a replacement key fob or additional one.

When you press the button on a key fob, the microchip transmits an indication to the receiver in the car that it is paired. The receiver compares the information with the 'allowed signals' stored on the key fob and then it opens or closes the car's doors. If the data does not match, the car will not be allowed to drive.

After the car has been associated with a particular fob, it can only receive signals from that device. Other fobs will not work with the car, even though they look similar. This is to safeguard the integrity of the vehicle's computer system and prevent unauthorised key fobs from taking control over the vehicle.

Most newer car dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security expertise that is only available in the dealer service department. Some aftermarket fobs, usually those from older models with less advanced systems, can be programmed without the need for a dealer.
