This is because the key has not yet been programmed into the car's system. This can be expensive. It is recommended to have two keys that are compatible for your modern car so you can program the replacement key if needed.

A keyprogrammer can recode a transponder chip on a new mechanical key or key fob. It can also clone the data of an existing key which allows duplicate keys to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with the computer, and they also have bidirectional interfaces to work with the immobilizer system.

Transponder Chips

Transponder chips are likely be found in vehicles manufactured in the last 20 years. 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 your vehicle.

The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is then amplified by the specific antenna that is positioned around the ignition barrel of your vehicle. The computer system of the vehicle can then verify that the key's transponder chip is the right one for your car.

This is the reason why from modifying or hot-wiring the ignition system of your vehicle to get it started. The chip in the key also verifies that you are the legal owner of the vehicle. This helps to prevent car theft.

Transponder keys appear like regular keys made of metal but have caps made of plastic. The chip is located inside the plastic portion of the keys. There are several different cuts such as a standard cut Laser cut (also known as a sidewinder or Ford Tibbe), and Ford Tibbe.

A circuit within the induction coil emits a signal when the transponder is put into the ignition barrel. The signal will be taken up by the chip, causing it to transmit a signal to the car. If the computer in the car recognizes the signal as correct, it will disable vehicle immobilizer, allowing the engine to start.

If the car does not recognize the transponder signal as being the proper one, it will keep the engine from starting and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage those who would attempt to alter the vehicle. However it isn't an unbreakable security measure. A skilled and determined thief may still be able to bypass this system by using a device that can take over the signal.

As you can see there are quite a number of benefits to having transponder key programming keys. All car owners should consider this if they wish to protect their investment and minimize the chance of theft.

Key Fobs

Key fobs today can do more than just lock and unlock doors. They can also turn on the car remotely, make chirping noises to help locate a car or turn on the heated steering wheel. A lot of these additional features might seem useful however they could make it harder for you to keep track of your car keys.

Key fobs communicate with one other and the car using radio frequencies that are transmitted via an antenna that is located in the center of the key. This communication is encrypted, which helps prevent others from intercepting and re-transmitting the signal.

Keyfobs can be programmed in a variety of ways depending on the make and model of your car. It is possible to do this 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 signals to the receiver in the car with which it is paired. The receiver compared the information with the permitted signals stored in the key fob, and then it opens or closes the car door. If the data doesn't match, a chirping sound is heard and the car isn't allowed to operate.

Once the car is linked with a particular fob, it will only receive signals from that specific device. Other fobs won't work with the car, even if they appear identical. This ensures the security of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control over it.

Most newer car dealers will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. It is because the only place with the experience to design an appropriate replacement fob is the service department of the dealer. Some fobs from the aftermarket, especially those for older models that have less sophisticated systems can be programmed with out the need for a dealer.
