The reason for this is that the new key has not been programmed to the automobile's system, and this could be quite expensive. This is why it's a great idea to have two working keys for a modern car and have the replacement key programmed if necessary.

Keyprogrammers can recode the transponder chip on the new mechanical key or key fob. It is also able to copy the data of an existing key to make duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software that enables them to communicate with the computer as well as an interface that works bidirectionally with the immobilizer system.

Transponder Chips

Transponder chips are likely to be found in vehicles manufactured within the last 20 years. It's a tiny piece of plastic inside the head of your key which contains a 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 an antenna attached to the barrel of ignition. This allows the computer in your vehicle system to verify that the transponder key programmer chip that is in the key is the correct one for the car you have.

This is what prevents from modifying or hot-wiring the vehicle's ignition system to get it started. The chip in the key also proves that you are the legitimate owner of the vehicle. This will help reduce car theft.

Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is inside the plastic portion of the keys. There are various cuts: a standard cut, Laser cut and program car key (also known as a sidewinder or Ford Tibbe) and Ford Tibbe.

A circuit inside the induction coil will emit an electrical signal when the transponder is placed in the the ignition barrel. The signal will then get received by the chip, causing it to transmit a signal to the car. If the onboard car computer detects this signal as the correct one, it will disable the vehicle immobilizer and allow the engine to begin.

If the vehicle doesn't recognize the transponder signal as the proper one, it will keep the engine from starting and will notify you by flashing its lights and sounding a siren. This feature is designed to deter people from trying to alter the vehicle, however it isn't a foolproof security measure. A skilled and determined thief may still be able to get around this system using a device that can detect the signal.

You can see that the transponder is a good option. Every car owner should take this into consideration if they wish to protect their investment and decrease the chance of theft.

Key Fobs

Key fobs today can be more than just a way to lock and unlock doors. They can also turn on the car remotely, emit chirping sounds to aid in finding the car or turn on the heated steering wheel. These additional features can make it difficult to locate your car keys.

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

Keyfobs can be programmed in different ways based on the model and brand of your vehicle. Some cars allow you to do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer for them program a replacement key fob or additional one.

When you press a key fob's button, the microchip inside transmits an encoded code to the car's receiver that it is linked to. The receiver compared this information with the 'allowed' signals inside the fob, and either locks or opens the door. If the information doesn't match, the car will not be allowed to run.

Once the car has been associated with a particular fob, it will only accept signals from that device. Other fobs won't work with the car, even if they appear similar. This protects the integrity of the computer system in the car and blocks unauthorized key fobs gaining control of it.

The majority of newer dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security knowledge that is only available in the dealer service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems -- can be programmed by consumers without the need for dealers.
