These tools are not generally available to the public and are only used by professionals. This type of programming is known as EEPROM Programming. It requires the ability to solder, electronic skills and a lot of time.

Other kinds of key programming can be performed by anyone. They are accomplished using the onboard diagnosis port, which is accessible by a specific tool for key-fob programming. This method can be done by a locksmith who is trained with the help of an online guide or an owner's manual.

Key Programmers

Modern vehicles require a key-programming process to set up their systems and then start the vehicle. In certain instances, the key will need to be programmed by an auto locksmith or dealer.

This can be quite costly. This is why it's a good idea to always have two keys that work for a modern car and have the replacement key programmed if necessary.

Keyprogrammers are devices that can recode the transponder chip into the form of a new key fob or mechanical key. It is also able to copy the data of an existing key and allow 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 have a bidirectional interface for working with an immobilizer system.

Transponder Chips

If your car is made within the past 20 years, chances are it contains a transponder chip within of it. This is a little plastic piece on the back of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.

The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by an antenna that is attached to the ignition barrel. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the correct one for your vehicle.

This is what stops hot-wiring or tampering with the vehicle's ignition system to turn it on. The chip in the car key verifies that the owner is the person who owns the vehicle. This will help reduce car theft.

Transponder keys resemble regular metal keys but they have a plastic cap. The chip is housed within the plastic part of the key and there are a few different kinds of cuts available on these keys: a regular standard cut laser cut (also called a sidewinder key) or Ford Tibbe key.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal is received 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 vehicle immobilizer, allowing the engine to start.

If the vehicle doesn't recognize the transponder signal as being the correct one, it will keep the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage people from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined criminal may still be able to get around this system using a device that can take over the signal.

It is evident that the transponder is a good option. This is something that all car owners should consider if want to safeguard their investment and minimize the risk of theft.

Key Fobs

Key fobs today can offer more than locking and unlock doors. They can also start the vehicle from a distance, make chirping sounds to help locate cars, or turn on the heated steering wheel. A lot of these additional features may seem convenient but they could make it difficult for you to keep the track of your car keys.

Key fobs make use of radio frequencies to connect with one another and with the car. These frequencies are transmitted by a small antenna inside the middle of the key. The signal is encrypted to block other key fobs from stealing or modifying the signal.

Keyfobs can be programmed in a variety of ways depending on the model and brand of your car. Certain cars let you do it yourself. However, most newer models require you to visit an expert locksmith or dealer in order for them program a replacement key fob or an additional one.

When you press the button on a key fob, the microchip sends signals to the receiver inside the car that it is paired. The receiver compares the information with the 'allowed signals' stored in the key fob and then locks or opens the car's doors. If the information doesn't match an chirping sound is heard and the car isn't able to operate.

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, even though they look identical. This is to safeguard the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.

Most newer car dealerships will only accept cars that have original fobs, or genuine replacements offered by the manufacturer. The reason for this is that the only place with the experience to design a replacement fob is in a dealer's service department. Some fobs from the aftermarket, especially ones for older models that have less advanced systems, can be programmed without the need for a dealer.
