These tools are usually not accessible to the general public and are only used by professionals. This kind of key programming is called EEPROM programming a key. It requires soldering skills, electronic knowledge and a lot time.

Other kinds of programming car keys are much simpler and can be done by anyone who is able to. They can be done by using the onboard diagnosis port, which is accessible by a specific tool for key-fob programming.

Key Programmers

Modern vehicles frequently require a key programming procedure to start the system of the vehicle and allow the vehicle to begin. In a number of cases the key needs to be configured by the dealer or an auto locksmith. The key may not function correctly or will not start the car in any way. This is because the new key has not been programmed to the automobile's system - and this can be quite costly. This is why it's a great idea to have two keys that work for a modern automobile, so you can get the replacement key programmed when required.

A keyprogrammer can reprogram the transponder chip on a new mechanical key or key fob. It can also clone the data from an existing key which allows duplicate keys to be made. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with computers. They also feature a bidirectional user interface to work with an immobilizer system.

Transponder Chips

Transponder chips can be found in cars manufactured within the last 20 years. It's a tiny piece of plastic in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.

When it is activated by an electro-magnetic field, the chip emits a low-level signal. This signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system of the vehicle will then confirm that the chip in the key's transponder is the right one for your car.

This is what prevents hot-wiring or tampering with the vehicle's ignition system to get it started. The chip inside the key verifies that the owner is the person who is the owner of the vehicle. This can reduce car key programer theft.

Regular transponder keys are shaped like regular metal keys with a plastic top. The chip is contained in the plastic portion of the key and there are different kinds of cuts available on these keys: a regular standard cut laser cut (also called a sidewinder), or a Ford Tibbe key.

A circuit within the induction coil will emit signals when the transponder is placed in the the ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer on the car detects this signal as the correct one, it will disable the immobilizer on the vehicle and allow the engine to start.

If the car isn't able to recognize the transponder as a valid signal, it will not start the engine and will notify you via flashing lights and an alarm. This is designed to deter people from trying to hack into the vehicle, but it is not a foolproof security measure. A skilled and committed thief may still be able to get around this system using a special device to detect the signal.

As you can see there are quite a number of advantages to having a transponder key. This is something that all car owners should consider if they want to protect their investment and decrease the chance of theft.

Key Fobs

Key fobs today do more than just lock and unlock doors. They can also start your vehicle remotely, make chirping noises to aid in finding cars, or switch on the heated steering wheel. A lot of these features may seem convenient but they could make it more difficult to keep the keys to your car.

Key fobs use radio frequencies to connect with one another and with the car. The frequencies are transmitted through a small antenna located within the middle of the key. This communication is encrypted, which helps prevent others from intercepting and retransmitting the signal.

There are several ways to program a key fob depending on the vehicle's make and model. Certain cars let you do it yourself. However, most newer models require you to visit a professional locksmith or dealer to program a new key fob or an additional one.

When you press the button on your key fob the microchip inside sends an encoded code to the car's receiver it is linked to. The receiver then compares this information with the signals that are allowed inside the fob, and either opens or locks the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to function.

Once the car is linked with a specific fob it will only accept signals from that device. Other fobs will not work with the car, despite the fact that they look like. This is to safeguard the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control of the vehicle.

The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place that has the expertise to prepare the replacement fob is a dealer's service department. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by consumers without the need of a dealership.
