These tools aren't usually available to the public and are only used by professionals. This type of programming is referred to as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.

Other kinds of key programming can be carried out by anyone. They are typically accomplished by using the diagnostics port on the car, which can be accessed with the key-fob-programming device.

The key may not function properly or not start the car at all. The reason is because the new key has not been programmed into the vehicle's system, and this could be very costly.

A keyprogrammer can reprogram the transponder chip of a new mechanical key or key fob. It is also able to clone information from an existing key, allowing duplicates to be made. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with a computer.

Transponder Chips

Transponder chips can be found in cars that were manufactured in the last 20 years. It's a small plastic piece on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.

When it is activated by an electromagnetic field, the chip emits a low-level signal. The signal is then taken up by an antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to determine if the transponder chip that is in the key is the correct one for your particular car.

This is the reason why doing hot-wiring or altering the ignition system of the vehicle to get it started. The chip inside the mobile key programming ensures that the owner is the person who is the owner of the vehicle. This can help to reduce car theft.

Transponder keys resemble regular keys made of metal but they have a plastic cap. The chip itself is housed in the plastic portion of the key, and there are different cuts that can be found on these keys: a standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal is received by the chip which sends a signal to the vehicle. If the computer in the car detects the signal as correct, it will disable vehicle immobilizer, allowing the engine to start.

If the vehicle doesn't recognize the transponder signal as being the right one, it will prevent the engine from starting and will notify you by flashing its lights and sounding a siren. This system is designed to deter those who would attempt to alter the vehicle. However it isn't a foolproof measure of security. 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 few advantages to getting a transponder key. This is something that all car owners should consider if want to protect their investment and minimize the chance of theft.

Key Fobs

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

Key fobs utilize radio frequencies to communicate with one another and the car. These frequencies are transmitted by a small antenna within the middle of the key. This communication is encrypted to stop others from stealing or modifying the signal.

There are many ways to program a key programming car fob based on the model and make. Certain cars let you do this by yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a replacement key fob, or an alternative one.

When you press the button on a key fob the microchip sends an indication to the receiver inside the car that it is paired. The receiver compares this information with the 'allowed' signals inside the fob, and either opens or closes the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to operate.

Once the car has been paired with a specific fob, it will only accept signals from that device. Other fobs won't work with the car, despite the fact that they look similar. This is to safeguard the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.

The majority of car key programmed dealers who are newer will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise which can only be obtained in the dealer's service department. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by the consumer without the need for dealers.
