These cars require a transponder-chip-integrated key to be programmed by a professional locksmith, mechanic or dealer in order to function properly.

Professional locksmiths are able to perform various kinds of programming for car keys. Some are very complex and may require sophisticated tools. These tools are generally not available to the general public and are used only by professionals. This kind of programming is referred to as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.

Other kinds of programming car keys are much easier and can be accomplished by anyone who is able to.

Keyprogrammers can recode a transponder chip on the new mechanical key or programming keys key fob. It can also clone the data from an existing key and allow duplicate keys to be made.

Transponder Chips

If your car was built in the last 20 years, it is likely that it has a transponder chip inside of it. It's a small piece of plastic on the back of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.

When it is activated by an electro-magnetic field the chip emits a low-frequency signal. This signal is then received by a specific antenna 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 right one for your particular car.

This stops the vehicle from being started through either hot-wiring or by altering the key. The chip in the key also proves that you are the genuine owner of the vehicle. This helps to prevent car theft.

Transponder keys that are regular in shape like regular metal keys 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 (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe.

The circuit in the induction coil emits an electrical signal when the transponder is put into ignition barrel. The signal will then get absorbed by the chip, causing it to transmit a signal back to the car key programming cost. If the computer in the car is able to recognize the signal as being correct it will turn off the car immobilizer so that the engine can start.

If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and will alert you with flashing lights and a siren. This is designed to discourage people from trying to hack into the vehicle, however it isn't a foolproof security measure. A skilled and committed thief may still be able to get around this system using a device that can intercept the signal.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely, or making noises to aid in finding a car in a parking lot, today's key fobs can also turn on a heated steering wheel, or roll down all of the windows with a single button press. These extra features can make it difficult to find your car keys.

Key fobs use radio frequencies to connect with one another and with the car. These frequencies are sent through a small antenna located within the middle of the key. This signal is encrypted to block other key fobs from stealing or stealing the signal.

You can program a keyfob in different ways based on the make and model of your car. Certain models allow you to do this yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order to program a new key fob, or an alternative one.

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

After the car has been associated with a particular fob, it can only receive signals from the device. As a result, other fobs won't be able to work with the vehicle even though they appear similar. This ensures the security of the computer system that runs the vehicle and stops unauthorized key fobs gaining control over it.

Most newer car dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. It is because the only place that has the experience to design a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
