The cars require a transponder chip-integrated key to be programmed by a professional locksmith, car dealer or mechanic for proper operation.

Professional locksmiths can carry out various types of programming for keys to cars. Certain types are extremely complex and require sophisticated tools. These tools are not generally available to the public and are used only by professionals. This type of programming for car keys is known as EEPROM Programming and requires soldering, electronic skills and a significant amount of time.

Other types of programming for car keys are much simpler and can be performed by anyone who is able to.

Key Programmers

The key may not work correctly or will not start the vehicle in any way. This is because the new key hasn't been programmed to the automobile's system. This can be quite expensive. This is why it's a great idea to have two keys that work for a modern car and to have the replacement key programmed when necessary.

A keyprogrammer is a device that recodes the transponder chip into a new mechanical or key fob key. It can also clone the data of an existing key and allow duplicate keys to be created. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that enables them to communicate with the computer and also provide bidirectional interfaces to work with the immobilizer system.

There are a myriad of types of keyprogrammers available on the market. They come in all shapes, sizes and colors. Some keyprogrammers are cheap while others could cost thousands of dollars.

Transponder Chips

Transponder chips are likely to be found in vehicles manufactured within the last 20 years. It's a tiny plastic thing on the back of your key which contains an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.

When it is activated by an electro-magnetic field the chip emits a low level signal. The signal is received by a specific antenna attached to the ignition barrel. The computer system in the vehicle is then able to verify that the key's transponder chip is the right one for your car.

This is what prevents from modifying or hot-wiring the ignition system of your vehicle to start it. The chip in the key also verifies that you are the genuine owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

Transponder keys appear like regular metal keys but have caps made of plastic. The chip is contained inside the plastic portion of the key and there are different types of cuts on the keys: a standard cut and program car keys, a laser cut and program Car key (also called a sidewinder) or Ford Tibbe key.

A circuit within the induction coil emits a signal when the transponder is inserted into an ignition barrel. The signal will then get absorbed by the chip and cause it to transmit a signal to the car. If the computer in the car is able to recognize the signal as being correct it will turn off the vehicle immobilizer so that the engine can start.

If the car isn't able to recognize the transponder as being the proper signal, it won't start the engine and alert you with flashing lights and an alarm. This feature is designed to discourage people from attempting to hack into the vehicle, however it is not a foolproof security measure. A skilled and skilled criminal could still evade this system using a special device that intercepts the signal.

As you can see there are quite a number of benefits to having transponder keys. Every car owner should consider this when they want to safeguard their investment and minimize theft risk.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely, or making chirping sounds to help find a car in a parking lot, today's key fobs can also switch on a heated steering wheel, or roll down all windows with a single button click. These additional features can make it difficult for you to locate your car keys.

Key fobs communicate with each with the car via radio frequencies that are transmitted through an antenna in the center of the key. This signal is encrypted to prevent others from intercepting or replicating the signal.

Keyfobs can be programmed in a variety of ways depending on the model and brand of your vehicle. It is possible to do this yourself, however most modern automobiles require an expert locksmith or dealer to program a replacement or additional fob.

When you press the button on a key fob, the microchip sends signals to the receiver inside the car with which it is paired. The receiver then compares this information to the signals that are allowed inside the fob, and either opens or closes the door. If the data does not match the signals, the car will not be allowed to operate.

Once the car is paired with a specific fob it will only receive signals from that specific device. This means that other fobs won't work with the vehicle even if they appear similar. This ensures the security of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control of it.

Most dealerships with newer cars will only work with cars with original fobs, or genuine replacements sold by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security expertise that can only be found in the dealer's service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems -- can be programmed by customers without the need for a dealership.
